The answer is B! Photosynthesis Inputs/Reactants are: Water, Sunlight, and Carbon Dioxide. Output/Products are: Oxygen and Glucose (sugar)

Answer:

B. Oxygen Gas and Molecules Of Sugar

Explanation:

Photosynthesis is the process through which plants make their own food.

Special structures called chloroplasts—located inside plant cells—help plants capture light energy from the Sun. The plants then use the energy to build molecules of sugar from carbon dioxide gas and water. Oxygen gas is a waste product of photosynthesis. Plants releases this waste oxygen into the air.

It aould be A. By breaking down food molecules and building new molecules. The food we eat contains kilocalories , which give us energy. If we eat plants, or producers, then we get more kilocalories than if we eat a primary, secondary, or tertiary consumer.

Final answer:

The subunits of DNA, known as nucleotides, consist of a pentose sugar, a phosphate group, and a nitrogenous base. There are four bases: adenine, thymine, guanine, and cytosine, which are responsible for storing and transmitting genetic information to synthesize proteins.

Explanation:

Subunits of DNA and Their Functions

The subunits of DNA are called nucleotides. Each nucleotide is made up of three parts: a pentose sugar called deoxyribose, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine (A), thymine (T), guanine (G), and cytosine (C). The sequence of these bases forms the genetic code, which carries instructions for making proteins. DNA's structure facilitates its replication and the encoding of genetic information, while its packaging into chromosomes allows for the organization and distribution of genetic material during cell division.

Function of DNA Nucleotides

The sequence of the four bases along the DNA helix determines the genetic instructions for building proteins, which are vital for the structure, function, and regulation of the body's tissues and organs. Despite all human cells containing the same DNA, they can look and function differently due to the differential expression of genes and the complex process of gene regulation.

Carrying capacity of an ecosystem is the defined as the largest population that it can sustain indefinitely with the available resources. Biologists also refer to carrying capacity as the “maximum load”. Carrying capacity has factors it depends on. These are the many abiotic and biotic factors in the ecosystem and some are more obvious than others.  The most obvious being, the availability of the basic needs of organisms which make up the different ecosystems. Some of these are food, water and shelter in which dictate how many individuals the ecosystem can sustain.

Uhhhh C I think. Mitochondrion is used to make ATP which is energy so I think it is energy production

Answer: The correct answer would be option C.

Explanation:

Mitochondrion, also known as energy house of the cell, is a cell organelle mainly involved in the production of cellular energy, that is, ATP.

It is a double membrane-bound cell organelle which contains majority of enzymes involved in cellular respiration including ATP synthase.

All the metabolic processes involved in cellular respiration apart from glycolysis take place in mitochondria only. For example, Krebs cycle, oxidative phosphorylation, electron transport chain, chemiosmosis, et cetera.

Thus, if a cell contains numerous mitochondria then, the main function of the cell would be energy production.

Carbon and nitrogen are examples of nutrients. Unlike energy, matter is recycled in ecosystems. ... Decomposers release nutrients when they break down dead organisms.

How Matter Moves Through Ecosystems

Living things need nonliving matter as well as energy. What do you think matter is used for? It's used to build bodies. It's also needed to carry out the processes of life. Any nonliving matter that living things need is called a nutrient. Carbon and nitrogen are examples of nutrients. Unlike energy, matter is recycled in ecosystems.

Decomposers release nutrients when they break down dead organisms.

The nutrients are taken up by plants through their roots.

The nutrients pass to primary consumers when they eat the plants.

The nutrients pass to higher level consumers when they eat lower level consumers.

When living things die, the cycle repeats.Summary

Nutrients are crucial to the growth of organisms.

Decomposers break down dead organisms into nutrients and gases so that they can be used by other organisms.

Nutrients can enter or exit an ecosystem at any point and can cycle around the planet.

WHY? to conserve what we have, for matter being recycled helps the ecosystem and its good for our planet!

The answer is b global warming

Answer: B) global warming

Explanation:

The burning of the fossil fuels liberates carbon dioxide and other harmful gases into the atmosphere. These gases are capable of causing greenhouse effect. As, these gases are diatomic these are capable of absorbing the light energy from sun causing the global temperature warm. The heat liberated from the terrestrial land and some energy from sun are reflected back to the space so as to prevent the earth from accumulation of excess heat energy. These gases being trapping the sunlight energy nullify the heat reflection process. Hence, increasing the global heat causing global warming.

I think C sorry if I am wrong

Answer:

C) The ecosystem will be able to support more organisms at higher trophic levels.

Explanation:

In ecology, primary productivity is understood as the efficiency of converting energy to organic substances from the reaction of autotrophic organisms by solar or chemical energy. That is, this productivity is related to the action of plants in photosynthesizing solar energy creating organic substances that will be absorbed by consumers along the food chain. The increase of this primary productivity results in the increase of plants and consequently in the increase of primary, secondary and tertiary consumers. From this we can state that the long-term effect of increasing the primary productivity of a terrestrial ecosystem results in an ecosystem's greater capacity to support more organisms at higher trophic levels.

Thank you.

Answer:

The correct answer is option B) It can make antibodies immediately.

Explanation:

The secondary immune response occurs when the same antigen is exposed to the person more than one time. The immune system immediately starts making antibodies to attack the antigen. By the second time, memory cells are established and start making antibodies immediately. The lag phase is shorter as compared to the primary immune response. Memory cells are cells responding cells for secondary immune response.

Drilling oil wells reduces deforestation. The oil extraction process results in the release of toxic drilling by-products into local rivers, while broken pipelines and leakage result in persistent oil spillage. In addition, the construction of roads to access remote oil sites also signifies take trees out of the way.

Deforestation reduces the habitat for millions of species. Eighty percent of Earth’s land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes.  It also affects climate change. Forest soils are moist, but without protection from sun-blocking tree cover, they quickly dry out. Trees also help perpetuate the water cycle by returning water vapor to the atmosphere. Without trees to fill these roles, many former forest lands can quickly become barren deserts. hope it helped.

The advancement in oil drilling that has substantially reduced the environmental impact of drilling is directional drilling.

The advancement in oil drilling that has substantially reduced the environmental impact of drilling is known as directional drilling.

Directional drilling is a technique where the drill bit is steered to reach the desired oil reservoir by deviating from the vertical. It allows for drilling multiple wells from a single location, reducing the number of surface disturbances, and minimizing the footprint of the drilling operation. This technique also reduces the need for additional access roads and infrastructure, minimizing the impact on the environment.

Another advantage of directional drilling is that it allows access to oil reserves that are located beneath sensitive environments, such as national parks or protected areas. Instead of having to drill directly underneath these valuable habitats, directional drilling can reach the oil reservoir from a distance, avoiding any potential harm to the environment.

the correct asnwer is e

Answer:

B. Normal fault

Explanation:

The image shows a normal fault which happens when the hanging wall moves downward from the footwall, and this type of faults occur when two blocks of rock are pulled away from eachother, and in that case on of the walls becomes the hanger, which means that it goes downwards from the normal or other wall, and that becomes the footwall.

Without seeing an image, it’s impossible to identify the fault type. The available options are Normal Fault (hanging wall drops due to tension), Reverse Fault (hanging wall rises due to compression), Lateral Fault (plates slide horizontally), or Thrust Fault (a type of Reverse Fault with a nearly horizontal angle).

Without being able to see an image of the actual fault, I'm unable to provide a definite answer as to whether it's a Lateral Fault, Normal Fault, Reverse Fault, or Thrust Fault. However, I can explain the difference between them. A Normal Fault occurs when the hanging wall drops down relative to the footwall, generally due to tension in the Earth's crust. A reverse fault is the opposite, when the hanging wall is shoved up relative to the footwall, due to compression in the Earth's crust. A lateral fault is when two tectonic plates slide past each other horizontally, while a thrust fault is a type of reverse fault where the angle of the fault plane is near horizontal.

2. from the Sun to the surface of the Earth, where it is absorbed or reflected

Explanation:

The solar radiations come from the Sun and enter the atmosphere to hit the ground of the earth. Part of the solar radiations is absorbed by the atmosphere and other materials present on the surface of the earth. The earth surface also absorbs part of the solar radiations.

However, the surface of the earth reflects some radiations back to space at night. Hence, solar radiations are released from Sun after which they hit the surface of the earth where they are absorbed or reflected.

oxygen reacts with glucose in respiration

Glucose reacts with oxygen to form carbon dioxide and water, releasing energy during cellular respiration. The correct answer to what reacts with glucose is A. oxygen.

Carbohydrates react with oxygen in order to complete the reaction where glucose is converted into carbon dioxide and water during cellular respiration. By definition, carbohydrates contain carbon, hydrogen, and oxygen. This means that glucose, a carbohydrate with the formula C6H12O6, already has oxygen within its molecule. When glucose reacts with additional oxygen molecules, the process results in the formation of carbon dioxide (CO2) and water (H2O), releasing energy that cells can use.

The chemical equation for the reaction is:

C6H12O6 + 6 O2 → 6 CO2 + 6 H2O

This shows that each molecule of glucose requires six molecules of oxygen to complete the reaction. Therefore, the correct answer to the question is A. oxygen

A chordate is any member of the phylum Chordata which includes three sub-phyla; Vertebrata (vertebrates), Urochordata (tunicates) and Cephalochordata (lancelets). Chordates usually have a notochord (a stiff dorsal supporting rod) at some stage of their development. In vertebrates, this develops into spine. They also have pharyngeal slits and a tail.

Examples of chordates are vertebrates such as humans, pandas and alligators.

Vertebrata is the biggest group within the chordates. Members of this sub-phylum are characterized by their vertebral column which is made up of several bony vertebrae joined together as a backbone .

Answer: A chordate is an organism in the phylum Chordata (which includes the vertebrates). Every chordate possesses 5 defining characteristics at some point in its life. These include a notochord, a dorsal nerve chord, an endostyle or a thyroid, pharyngeal slits, and a postanal tail. The largest group of chordates are the vertebrates.
