The amount of harmful gases like carbon dioxide, sulfur dioxide, nitrogen oxide from bike is less as compared to that of car.

Warm temperate climates are classified as a climate region with distinctive summer and winter seasons. This kind of climate help in maintaining constant body temperature.

Biological diversity (biodiversity) refers to the diversity of life throughout all levels of biological organization, including not only the total number of life forms found in a given region but also the scope of variations among those forms.

Biodiversity encompasses everything from genetic variation within a single simple population to the diversity of ecosystems throughout the world.

Scientists believed the warm climates provide greater biodiversity because there is an abundant amount of rainfall seasonally in the warm climatic region to increase crop productivity which in turn results in greater Biodiversity.

Also, in the warm-climate region, species are exposed to greater genetic diversity, this makes the species to be adapted to various conditions such as resistance to climate change, therefore increasing Biodiversity.

In conclusion, from the above explanation, we now have a clear understanding on how warm climates improve biodiversity.

Potential energy; energy created by the position of an object.

As you observe in the image, both 02 and CO2 enters the plant and both are utilized by the plants as well in the process of respiration and photosynthesis respectively. Look at the reaction:

During Respiration O2 is utilized and CO2 is liberated out by the plant:        

oxygen + glucose -> carbon dioxide + water + heat energy

During Photosynthesis CO2 is utilized and O2 is released:    

carbon dioxide + water+ light energy -> oxygen + glucose

During photosynthesis, plants create their own food (glucose) whereas during respiration, plants consume glucose and convert it into energy which fuels the plants cellular activities.

The Answer Fam Is

Plants require carbon dioxide for photosynthesis and produce oxygen as a byproduct. They then use the oxygen released in cellular respiration, producing carbon dioxide as a byproduct.

Water moves upward through a plant through the xylem tissue. Along with water, xylem also transports dissolved minerals, and some small organic molecules. Three factors that influence the flow of sap through a plant include diffusion, transpiration and capillary action. Water transport occurs in a plant's xylem tissue.

RE: "A."

Plants get energy from the sun (photosynthesis), but the production of Carbon Dioxide does not give any living thing the energy to perform their life processes.

RE: "B."

The Moon's reflective light does not give any living thing the energy to perform their life processes.

RE: "C." [Best answer]

The breakdown of food does give any living thing the energy to perform their life processes.

RE: "D." Plants' roots "fix" Nitrogen gas from the atmosphere, but that does not give any living thing the energy to perform their life processes.

Final answer:

The correct option is C. the oxidation of food through the process of cellular respiration. Living things acquire the energy they need to perform life processes primarily through cellular respiration, where food is oxidized to release energy. This stored energy originates from photosynthesis, where plants convert sunlight into chemical energy.

Explanation:

All living things need energy to perform their life processes. They obtain this energy in various ways. One critical source of energy is the process of cellular respiration, where organisms oxidize food to release energy. This is option C: the oxidation of food through the process of cellular respiration. However, it's important to note that the ultimate origin of much of this energy is the sunlight captured by plants and other autotrophs through photosynthesis. In photosynthesis, light energy is converted into chemical energy, which is stored in carbohydrates. Cellular respiration then breaks down these carbohydrates to power the life processes of both plants and animals.

B. homozygous for the recessive allele.

The only way you have a disease caused by a recessive allele is that both of your copies are recessive.

The answer would be respiratory because that system is used to breath oxygen and exhale carbon

The nervous system is the organ system that is not used to obtain nutrients from food. The process of nutrient acquisition primarily involves the digestive and circulatory systems. The nervous system plays no direct role in the digestion or transportation of nutrients.

The organ system that does not contribute to obtaining nutrients from food is the nervous system. The process of obtaining nutrients from food primarily involves the digestive system, which breaks down the food into essential components like carbohydrates, proteins, and fats that our bodies can use. This includes organs such as the mouth, stomach, and intestines. Additionally, the circulatory system plays a vital role in transporting these nutrients to different parts of the body. The nervous system, on the other hand, is responsible for receiving, transmitting, and interpreting sensory information, playing no direct role in the digestion or transportation of nutrients.

Answer:- Option a  radial symmetry

Explanation:-

Most of the organisms have can either of the two types of symmetry:-

1. Bilateral symmetry- A body is said to have a bilateral symmetry when it can be divided into 2 equal halves on either side of a single  plane.

For e.g if you cut the letter M from middle vertically then you have two equal halves.

2. Radial symmetry - A body is said to be radially symmetrical if  it can be divided into similar halves in any plane. This means that the organism has its body parts arranged around a central main axis.

The cnidarians whether in polyp or medusa from exhibit radial symmetry because if you cut them in any plane you will get equal halves.

Answer:

Humans are more closely related to chimpanzees than carp.

Explanation:

The trade winds in the tropical zones are persistent, east-to-west winds influenced by the subtropical highs and the Coriolis effect. They converge at the Intertropical Convergence Zone (ITCZ), leading to wet conditions and the potential for tropical storms, and also contribute to oceanic upwelling. Additionally, outside of the tropical zones, westerly wind patterns known as the westerlies occur between latitudes 30° to 60°.

The zones near the equator where winds move predominantly from east to west are influenced by the trade winds. These trade winds are a component of the Earth's atmospheric circulation system and are moderate but persistent throughout the year. They mainly occur over the oceans and are particularly relevant in the tropical zones, pushing air towards the equator from the northeast in the northern hemisphere and from the southeast in the southern hemisphere.

Trade winds are steered by the subtropical highs and the Coriolis effect, which causes them to bend slightly to the right in the northern hemisphere and to the left in the southern hemisphere. When these winds converge near the equator, they form the Intertropical Convergence Zone (ITCZ), characterized by calm and wet conditions, which can give rise to tropical storms. These persistent east-to-west winds also facilitate oceanic upwelling and the transport of cold water across the Pacific Ocean.

Lastly, on the poleward side of the subtropical highs, the airflow contributes to the creation of westerly wind patterns, known as the westerlies, between the latitudes of 30° and 60° both in the northern and southern hemispheres. These dynamic air movements and their resulting climates play a crucial role in weather patterns around the globe, especially in the tropics and subtropics.

Answer:

These crops can fix nitrogen into usable nitrates.  

Explanation:

There are certain crops which are called cover crops, specifically legumes like peas, vetch,clover and winter field beans . Farmers grow these crops during winter before the growth of actual target crops like cabbage etc which are thirsty for Nitrogen.

What is special about these cover crops is their ability to fix nitrogen into the soil from the atmosphere. There are various ways through which these leguminous crops can fix nitrogen into the soil:

This phenomenon confers the leguminous crops with an ability to fix  nitrogen in the soil that can be used by the nitrogen requiring crops like cabbage when grown next season in same soil.

Hope it help!

Nitrogen fixation is the process by which nitrogen present in the earth,s atmosphere is converted into ammonia or to the interconnected nitrogenous compounds. Nitrogen fixation is important to life because fixed inorganic compounds are essential for the biosynthesis of the nitrogen containing compounds.

Some plants such as legumes have collaborating relationship with the diazotrophic bacteria which fix atmospheric nitrogen into ammonia. These bacteria contain nitrogenase enzyme whici is responsible for biological nitrogen fixation. The reaction for the nitrogen fixation is as follows

[tex]N_{2} +8H^{+} +8e^{-} -->2NH_{3} +H_{2}[/tex]

The majority of the plants which show symbiotic relationship with the diazotrophic bacteria are legume plants which belongs to Fabacae family.

Since most of the legume plants are grown during the winter season these plants fix nitrogen into suitable nitrates.

Therefore the answer is these crops can fix nitrogen into usable nitrates as most of the legume plants are grown during winter.

The protein component of the cell membrane function to actively transport molecules into the cell.

All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.

A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant microenvironment within the cell, and also that membranes serve a variety of purposes. One is to move compounds out of the cell that is harmful as well as nutrients into the cell. Another is that there will be proteins on the cell's membrane, which is its plasma membrane, that communicate with other cells.

These proteins may be lipid proteins, which include both a protein and a fatty acid, or they may be glycoproteins, which contain both a protein and a sugar moiety. Additionally, those proteins that adhere out of the cell membrane enable cell-to-cell communication.

Additionally, a cell's membrane offers some structural support. Additionally, various cell kinds have distinct types of plasma membranes, and the lipid component of the plasma membrane generally contains a lot of cholesterol. This is distinct from a few other membranes found inside the cell.

There are several plants and microorganisms, such as algae and bacteria that have various defense systems. They really have a cell wall surrounding them, which is stronger and more sturdy than a plasma membrane.

Therefore, proteins are the components involved in active transport.

Answer:

The Epidermis

Explanation:

The epidermis is composed of keratinized, stratified squamous epithelium. It is made of four or five layers of epithelial cells, depending on its location in the body.

The silent crickets survived because they weren't located by the Ormia ochracea flies. When these silent crickets reproduced, the 'silent' trait was passed on to the offspring. Over time, the cricket population rebounded, but with crickets that were silent due to this evolved defense mechanism against the lethal parasites.

The best explanation for the revival of the silent cricket population relates to evolutionary adaptation and behavioral changes brought on due to parasite infestation. The silent male crickets likely survived the parasite infestation because, not producing any sound, they were not detected and targeted by the Ormia ochracea flies whose maggot offspring are deadly for the crickets. Essentially, the flies were unable to locate the silent crickets.

These silent males reproduced with available females, passing on the 'silent' trait. Over time, the cricket population rebounded, but these new generation of crickets had evolved to be silent as a defense mechanism against the fly parasites. This demonstrates a clear case of natural selection, where the trait providing a survival advantage in a given environment increases in frequency within a population over successive generations.

Adaptation through natural selection led to the rebound of the cricket population in 2003. Silent crickets, less noticeable to the deadly flies, survived better and passed on more of their genes, resulting in a predominantly 'silent' cricket population.

The best explanation for the rebound of the cricket population by 2003 is the concept of adaptation due to natural selection. Cognizant of the dire threat presented by the maggots released by flies, some of the crickets likely underwent mutation that silenced their chirps, which renders them less noticeable to the flies. These silent crickets could survive better, reproduce more, and pass on more of their genes, including potentially the gene causing silence, to the next generation. This process of natural selection would eventually lead to a predominantly 'silent' cricket population. Elaboration The rebound in the cricket population aligns with how species adapt to predation pressures. If a species is strongly preyed upon, individuals with traits that make them less likely to be killed by predators will pass on their genes more frequently, leading to a population change.

Final answer:

Isaac Newton made monumental contributions to physics, including formulating the laws of motion and the law of gravity, inventing calculus, and improving the theories of light and color, which remain foundational in physical science.

Explanation:

Isaac Newton's Contributions to Science

Sir Isaac Newton (1642-1727) was a pivotal figure in the history of science, making groundbreaking contributions across several fields. His most renowned work, the Philosophiae Naturalis Principia Mathematica, laid the foundation for classical mechanics through his laws of motion and the universal law of gravity. Besides these achievements, Newton invented calculus, which is fundamental to advanced mathematics and engineering, and greatly advanced the theories of light and color, impacting the field of optics.

Newton's laws of motion established a formulaic way to predict the movement of objects both on Earth and in space, marking a significant transformation from the Renaissance to the modern era of thought about the physical universe. This was a move away from the theologically-intertwined science of the past towards a model based on empirical evidence and mathematical precision. Through his work, Newton distilled the Scientific Revolution's findings, building upon the legacies of predecessors like Galileo and Kepler, to provide a comprehensive framework that remains influential in physics today.

Newton's methods and theories emphasized the importance of basing scientific inquiry on observation and experimentation rather than on established authority or solely philosophical reasoning. This approach was integral to the advancement of the Scientific Revolution, setting the stage for the modern scientific method.

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. hope this helps  and plz friend me  im jake  and im 13

The process through which the water is released from the plant to the environment is called as transpiration. The water from the root is passed on to the leaf surface through xylem by capillary action of water.

The water exhibits capillary action due to properties such as surface tension, cohesion, and adhesion. With the help of adhesion property, the water molecules binds with the xylem wall molecules, due to cohesion, the water molecules bind with one another and facilitates continuous as well as easy movement from root to the leaf through stem.

They will be able to tell how long you've been exposed to something poisonous because they will be able to see the changes that the poison has made to the blood stream, and the way it affects it.

Hope this helps!! (:

Final answer:

Hair samples are the most informative for determining how long someone has been exposed to a poison because they encapsulate a chronological record of exposure, unlike blood or muscle tissue which reflect recent exposures.

Explanation:

When it comes to understanding how long someone has been exposed to a poison, hair samples can provide valuable information. As hair grows, substances such as toxins can be deposited in the hair shaft, providing a chronological record of exposure. This is why hair analysis is often used in forensic toxicology when assessing long-term low-level exposure to toxins such as heavy metals, including arsenic, mercury, and lead. Blood and muscle tissues do not provide as clear a historical record of exposure because they are more reflective of recent exposures rather than a long-term timeline.

The right answer is : A Organisms that are heterozygous can pass on only the dominant allele.

Cystic fibrosis is a genetic disorder affecting the glandular epithelia of many organs. It is the most common lethal genetic disease with autosomal recessive inheritance in Europoid type populations, whereas it is very rare in African and Asian populations.

For a heterozygous subject, he has a recessive allele (the mutated allele) and a dominant allele (normal). In this subject the disease is not expressed as it is recessive compared to the normal allele, therefore, only the dominant allele will be expressed in subjects heterozygote for cystic fibrosis.
