alveoli
ExplanationDuring gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
The exchange of gases takes place in the alveoli.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
Additional information :- Alveoli are microscopic air sacs. They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.Atmospheric air contains little CO2, but blood flowing in pulmonary capillaries has a higher concentration of CO2.CO2 diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Can someone explain what polymers, monomers, and isomers are to me? What is the difference between isomers and polymers? Thanks, I'm studying for a test in about a week :)
Answer:
A monomer is a single unit of a substance (eg. Amino acid). A polymer is a chain of monomers (eg protein). An isomer is a molecule of an element with the same chemical formula but a different chemical structure (sucrose and maltose).

How does a forest fire impact a population of birds that nest in the trees.
Answer:
If a forest fire occurs it will impact a population of birds that nest in those trees because their habitat will be burnt down. This will provoke the birds to find a new habitat which can be hard if the entire forest is burnt down. Additionally resources such as food will be burned down as well.
a signal molecule which can bind to an enzyme and shut down its activity by altering the shape of the enzyme.
Answer:
Enzyme inhibitor
Explanation:
An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. By binding to enzymes' active sites, inhibitors reduce the compatibility of substrate and enzyme and this leads to the inhibition of Enzyme-Substrate complexes' formation, preventing the catalysis of reactions and decreasing the amount of product produced by a reaction.

how does carbon move through the system when there is light
Answer:
Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them.
Explanation:
The sun takes an integral role in the photosynthesis stage of the Carbon Cycle. Photosynthesis refers to the process by which plants take in carbon dioxide and water (the products of respiration), and convert it to oxygen, powered by the energy of the sun.
the sequence of events that produces another generation of organisms.
The sequence of events which produces another generation of organisms is called as the Life cycle.
What is Life cycle?Life cycle is defined as the series of changes which members of a species undergo from the beginning of a given developmental stage to the beginning of the same developmental stage in a subsequent generation.
In many simple organisms including bacteria and various protists, the life cycle is completed within a single generation where an organism begins by fragmentation of an existing individual and the new organism grows to maturity which then splits into two new individuals, so the life cycle is complete.
Thus, the sequence of events which produces another generation of organisms is called as the Life cycle.

They eat plants and other organisms which contain carbon and deposit carbon
into the soil when they die.
С
They remove carbon from the atmosphere during respiration and replace it with
oxygen that is used in photosynthesis.
D
They remove carbon from the soil during respiration and exchange it with
oxygen that evaporates into the atmosphere.
Answer:
B
Explanation:
B
They eat plants and other organisms which contain carbon and deposit carbon
into the soil when they die.
The correct option is B. They eat plants and other organisms which contain carbon and deposit carbon into the soil when they die.
What is carbon cycle?Carbon is the foundation of all life on Earth, required to form complex molecules like proteins and DNA. This element is also found in our atmosphere in the form of carbon dioxide (CO2).
Carbon helps to regulate the Earth’s temperature, makes all life possible, is a key ingredient in the food that sustains us, and provides a major source of the energy to fuel our global economy.

He placed biotic factors in first but needs to add some abiotic factors, two abiotic factors could he add Sunlight and Water.
What are abiotic factors in an ecosystem?An ecosystem is a place where biotic factors (that have a life) and abiotic factors (that have no life) converge, for the balance of the ecosystem both are necessary.
For example, in an ecosystem, animals and plants are the biotic factors, and among them, there are relationships such as animals that feed on other animals or others that feed on plants. But this life would not be possible if there were no factors such as water, sun, soil, oxygen, among others. So, the correct answer is C.
Thus, option "B and F" is correct.
