Which of the following describes how biological chemicals provide evidence to support that life changes over time?

A) some animals exhibit similar structures, possibly due to a common ancestor

B) some animals exhibit similar stages of embryonic development

C) some animals exhibit structures that are no longer used for any purpose

D) some animals exhibit similar proteins

The answer would be B. More windy.

Answer:

D. cooler

Explanation:

The answer to this question on Study Island is...

D. cooler

Because water has such a high "specific heat" ... it takes so much heat energy to raise the temperature of a pot or a glass of water by only 1 degree.  There's only one other substance on Earth that stores more heat than water does for such a small change in temperature.  (Liquid ammonia ... 12% more than water.)

That's one reason why, for example, we use water ice to cool our drinks ... it takes SO MUCH heat out of the drink just to melt the ice cube and then to warm up the melted freezing water that comes from it.

That's also why cities near the ocean or a big lake have cooler summers and warmer winters.  In the Summer, the water nearby takes lot of heat away from the city and stores it, without getting full of heat.  In the Winter, the warm water nearby pours out heat to keep the city warm, without running out of the heat that it holds.    

THAT IS A GREAT QUESTION

They are called trade winds.

The winds that blow from 30° latitude to near the equator are the northeast trade winds in the Northern Hemisphere and the southeast trade winds in the Southern Hemisphere, both influenced by the Coriolis effect and converging at the ITCZ.

The winds that blow from 30° latitude almost to the equator in both hemispheres are known as the trade winds. Specifically, these are the northeast trade winds in the Northern Hemisphere and the southeast trade winds in the Southern Hemisphere. Influenced by the Coriolis effect, these winds bend slightly to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The trade winds meet near the equator in a region called the intertropical convergence zone (ITCZ), where their collision can create very wet conditions, such as those found in equatorial rainforests.

Mitosis is a type of cell division in which a cell divides into two daughter cells, each containing equal and identical genetic material as that of the parent cell.

For example, if a cell contains 46 chromosomes (2n), then the two daughter cells would also contain 46 (2n) chromosomes after mitosis.

The mitotic division helps in growth and repair of cells.

In contrast, the meiosis is a cell division in which a parent cell divides to produce four daughter cells, each containing half the chromosomes present in a parent cell.

For example, a cell with 46 (2n) chromosomes divide with the help of meiotic division to produce 4 daughter cells, each containing 23 chromosomes.

The meiotic division usually helps in the production of haploid gametes from diploid parent cells.

Final answer:

Jamie should measure the total area of land or water resources that is needed to provide & transport the food.

Explanation:

When estimating the portion of his ecological footprint that arises from the food he eats, Jamie should measure the total area of land or water resources that is needed to provide & transport the food. The ecological footprint takes into account the land and water resources required for food production and transportation. This measurement helps determine how much impact Jamie's food choices have on the environment.

In estimating his ecological footprint from food, Jamie should measure the total land and water resources needed for production and transport (Option C) to comprehensively assess the environmental impact.

Jamie, in estimating the ecological footprint from the food he consumes, should measure the property related to the environmental impact of the food. Therefore, the most appropriate option is:

C. The total area of land or water resources that is needed to provide and transport the food.

This metric, often referred to as the "land and water footprint," assesses the spatial extent of resources required to produce the food, including agricultural land and water resources. It accounts for the environmental impact associated with food production, considering factors such as deforestation, water use, and habitat disruption.

Options A, B, and D focus on different aspects but are not as comprehensive in capturing the holistic environmental impact of food consumption. While the cost of food (Option A) may reflect economic considerations and the carbon footprint (Option B) addresses greenhouse gas emissions, they do not provide a comprehensive view of the broader ecological consequences. Similarly, measuring the total volume of resources (Option D) is important but may not encapsulate the spatial dimension of environmental impact as effectively as the land and water footprint.

The heart has two sides: the left side and the right side. Each side of the heart is divided into two parts, called the atrium and the ventricle. The atrium is the top part. The ventricle is on the bottom. Please give me the brailiest answer?

:) Hoped this helped!!! Have a good day!!! <3

The human heart is divided into four chambers, comprising two atria and two ventricles, which are separated into two sides by a septum. The correct answer to the question is B. two sides and four chambers.

The human heart is divided into four chambers. On each side of the heart, there is one atrium and one ventricle. The right side consists of the right atrium and right ventricle, mainly responsible for pumping deoxygenated blood to the lungs. Conversely, the left side comprises the left atrium and left ventricle and is tasked with pumping oxygenated blood to the rest of the body. Each atrium acts as a receiving chamber for blood and contracts to push blood into its respective ventricle. The ventricles are the main pumping chambers, forcing blood out of the heart to the lungs or bodily tissues. A septum divides the heart's left and right sides, and one-way valves ensure that blood flows in the correct direction, preventing any backflow. Based on this information, the correct answer to the student's question, "Into how many sections is the human heart divided?", is B. two sides and four chambers.

Answer:

A. Detect, feel, and smell

Explanation:

There are three main types of neurons: the sensory ones; the engines; and the interneurons. Sensory neurons carry information captured from the external environment to the nervous system, through stimulus receptors (whether mechanical or chemical). In this case, we can say that the main role of these neurons is to detect, feel and smell.

Interneurons, the most numerous group of neurons, transmit the signal from sensory neurons to the central nervous system. The motors conduct the response to the stimulus received, from the central nervous system to the stimulated organ or tissue.

The correct option is A. Detect, feel, and smell

Sensory neurons are specialized nerve cells that are responsible for detecting and transmitting sensory information from the environment to the central nervous system (brain and spinal cord).

They allow us to perceive and experience various sensations such as touch, pain, temperature, pressure, taste, and smell.

Sensory neurons are equipped with specialized receptors that detect stimuli from the external environment or internal body conditions and convert them into electrical signals that can be transmitted to the brain for processing and interpretation.

Therefore, option A, "Detect, feel, and smell," best describes the function of sensory neurons.

A nebula made of gas and dust red giant star

Most suitable for studying with radio waves would be a large galaxy made up of billions of stars due to its emission of radiation at radio wavelengths and the ability of radio waves to penetrate interstellar dust and gas.

Among the choices provided in the question, the best option studied using radio waves instead of light waves would be a large galaxy made of billions of stars. This is because radio waves provide a unique perspective into the universe with numerous benefits over studying with visible light.

Radio waves can penetrate interstellar dust and gas, providing an uninhibited view of galaxies and nebulae. This allows us to observe phenomena such as the jets of expelled material in the galaxy Cygnus A, visible only through radio observations. Astrophysical bodies containing a lot of gas and dust - much like a large galaxy - emit more radiation at radio wavelengths. This radiation can be observed without the interference of the Earth's atmosphere or the Galaxy's interstellar dust and gas. The Sun, on the other hand, is not especially bright at many radio wavelengths, making it less useful to study with radio telescopes.

Moreover, observations with radio telescopes can often be done during the day as well.  Radio emission maps reveal different properties of the universe than those visible in light, teaching us about the structure and properties of the universe on scales from our solar system to the universe as a whole.

For photosynthesis to occur, plants need sunlight, water, carbon dioxide and chlorophyll. Through the process of photosynthesis plants convert light energy into chemical energy. They use this energy to make food which they store as sugars.

Plants require sunlight, carbon dioxide, and water to carry out photosynthesis, converting them into glucose and oxygen as a result.

Light: Sunlight, or more specifically, the energy carried by photons in the visible spectrum, is the primary source of energy for photosynthesis. Chlorophyll, a green pigment found in chloroplasts, absorbs light energy and initiates the process.

Carbon Dioxide (CO2): Plants take in carbon dioxide from the atmosphere through tiny pores called stomata, primarily located on the underside of leaves.

Carbon dioxide serves as the source of carbon for the synthesis of glucose.

Water (H2O): Water is absorbed from the soil by plant roots. In the process of photosynthesis, water molecules are split in a process known as photolysis, releasing oxygen as a byproduct.

Chlorophyll: This green pigment found in chloroplasts is crucial for capturing light energy.

Chlorophyll molecules contain magnesium and are responsible for absorbing light, which starts the chemical reactions of photosynthesis.

Enzymes and Other Molecules: Several enzymes and molecules, such as NADP (nicotinamide adenine dinucleotide phosphate) and ATP (adenosine triphosphate), are involved in the various stages of photosynthesis to help convert carbon dioxide and water into glucose.

Chloroplasts: These are specialized organelles found in plant cells where photosynthesis takes place.

They contain chlorophyll and other pigments needed for the process.

Photosynthesis is a complex series of reactions that can be summarized as follows:

6 CO2 + 6 H2O + light energy → C6H12O6 (glucose) + 6 O2.

Question

What do plants need in order to perform photosynthesis?

The environment around the plant would not get nutrients.

Answer:

Disruption in number of plant species around the corn plant and hence the desalinization of ecosystem.

Explanation:

The other plants around the corn plant will be attacked and destroyed severely by the pests. Since corn is pest resistant, it will not be effected by pest attacks but other crops will get damaged.

In this way the biodiversity will reduce as the corn plants could not mate with any other plant species (which die due to pest attack).

hence, the ecosystem will get destabilize.

It was earthy centered in the solar system the church said God put us in the middle of the universe. It took along time for people to realize the stars move in such a way that we couldn't be the center.

Answer:

The correct answer will be option-earth-centered universe.

Explanation:

The ancient philosophers and scientists tried to understand the world so that the surrounding environment could be exploited.

The solar system was one of the systems, the ancient philosophers and astronomers tried to understand. The ancient recorded solar system model was proposed by the Ptolemy which stated that the earth is present in the center of the universe and all the celestial bodies revolve around it. This model is known as the geocentric model of the solar system.

Thus, the option-earth-centered universe is the correct answer.

The complete statement is this: Information that sensed in the right visual field is processed in the LEFT HEMISPHERE OF THE BRAIN.

The eye is an organ of sight that is used to receive physical stimuli in the form of light. The light is then sent as electrical stimuli to the brain for interpretation.

The eyes are constructed in such a way that, the left hemisphere of the brain process visual information from the right eye while the right hemisphere of the brain process information from the left eye. The optic chiasm, which is a complicated crossover of optic nerves fibers located behind the eyes at the bottom of the brain makes this to be possible.

Final answer:

Information sensed in the right visual field is processed in the left visual cortex, facilitated by the optic chiasm's sorting of visual information and maintained by the topographic relationship between the retina and visual cortex.

Explanation:

Information sensed in the right visual field is processed in the left visual cortex of the brain. This relationship is due to the way the visual pathway is organized, which involves the principle of contralateral control; however, nature enhances this system by ensuring that both eyes send information to both hemispheres of the brain. Each eye's input is divided at the optic chiasm, with the right visual field's information projected to the left visual cortex and vice versa. This system ensures that regardless of which eye captures the image, the sensory information will be thoroughly processed by both sides of the brain. Additionally, the visual cortex, located in the occipital lobe, maintains a topographic relationship between the retina and the brain, with superior and inferior visual information also processed accordingly, ensuring a correct representation of the visual field in our conscious perception.

First off, quick definition: molecules = a group of atoms/elements (not just a single element like "O" or "H", so all of these are molecules in this problem and we can instantly rule out answer choice D).

In this problem, your given chemical equation. The reactants (starting materials) are on the left side of the arrow (→). The products (finishing materials) are on the right side of the arrow. Sometimes special reactants (like enzymes i.e catalase) are written over top of the arrow instead of on the left side of the arrow.

Anyways, we can read this reaction like this:

- Start out with 2 molecules of [tex]H_{2}O_{2}[/tex]

- Add Catalase

- End up with 2 molecules of [tex]H_{2}O[/tex] (water) and 1 molecule of [tex]O_{2}[/tex] (oxygen)

Therefore, catalase must helped break down the bigger [tex]H_{2}O_{2}[/tex] molecules into the small "building block" molecules of [tex]H_{2}O[/tex] and [tex]O_{2}[/tex].

***SEE PIC FOR VISUAL...if you want. This always helped me. You can see easier that the bigger molecules are being broken down into multiple smaller ones***

The enzyme catalase is breaking down the molecule H2O2 (hydrogen peroxide) in the reaction.

In the presented chemical reaction, the enzyme catalase is breaking down the molecule H2O2, otherwise known as hydrogen peroxide. Enzymes are proteins serving as biological catalysts promoting chemical reactions inside cells. In this case, the catalase enzyme decomposes hydrogen peroxide (a harmful waste product in cells) into water and oxygen. This prevents the buildup of hydrogen peroxide which could be damaging to cells.

The correct order of the hominid species is:

1. Australopithecus afarensis;

2. Homo habilis;

3. Homo erectus;

4. Homo antecessor;

5. Homo heidelbergensis;

The hominid evolution we can say is a relatively short one from the first hominids to the modern humans, and also quite impressive, in which incredible evolution and development has taken place.

The first hominids are considered to be the australopithecines. It is though that they live in Eastern Africa. From them, we have a diversification of numerous species of hominids. The Homo habilis comes  later in the evolutionary tree, and it is a hominid that is already showing signs of great transformation, both physical and of its brain capacity. After that we have the Homo erectus, which had numerous subspecies, and it is the hominid that first started to use fire and create tools. Further in the evolutionary tree of the hominids we have the Homo antecessor of Western Europe and Homo heidelbergensis of South Africa, which are very close to the final shape of the modern day humans.

Ancestors of modern man listed from oldest to youngest are: Australopithecus afarensis, Homo habilis, Homo erectus, Homo antecessor, and Homo heidelbergensis, with Australopithecus afarensis appearing between 2 and 4 million years ago and being the oldest.

The ancestors of modern man can be listed from oldest to youngest based on the fossil record and scientific understanding of human evolution. Looking at the species provided, we can arrange them in the following order:

1. Australopithecus afarensis

2. Homo habilis

3. Homo erectus

4. Homo antecessor

5. Homo heidelbergensis

Australopithecus afarensis is known to have lived between 2 million and 4 million years ago. The genus Homo appears in the fossil record around 2.5 to 3 million years ago, with Homo habilis considered one of the earliest members, characterized by a larger brain and use of stone tools. Following Homo habilis, Homo erectus emerged around 1.6 million years ago and displayed further evolutionary adaptations such as increased brain size and complex tool use. Homo antecessor and Homo heidelbergensis are more recent but still predate modern humans.

To find the average of many values, add all the values and divide by the number of values.

The values are: 15, 8, 12, 12, 6, 18, 10, 15

There are 8 values.

Add the values: 15 + 8 + 12 + 12 + 6 + 18 + 10 + 15 = 96

Now divide the sum by the number of values:

average = sum/number of values

average = 96/8

average = 12

Answer: A   12

Answer:

A. 12

Explanation:

To find the average, we add all the values and divide them by the number of values which is 8.

so we have, 6+8+10+12+12+15+15+18=96

we divide 96 by 8

96÷8 =12.

We have cells from the hair on our heads to the nails on our toes. Our bodies have about 200 different  types in all. Cells form our muscles and bones. They help us turn food and oxygen into energy. They heal our wounds and keep us well. Cells perform their particular duties with strict protocols and in amazing order. They also communicate and cooperate with the cells around them. However, once their job has done all it can. and they have given their all, they kill themselves to make room for new, healthy cells.  This is how our bodies work to keep healthy and grow.

Bad cells (cancerous) are quickly killed by the immune system. Unfortunately, some of the damaged cells find ways to survive. Normal cells grow, divide and use their cellular machinery according to predefined rules in the cells but cancer cells mislead the body's signals causing the cancer cells to divide and spread.
