Answer:
Lungs.
Explanation:
Lungs are the organs that are responsible for gaseous exchange in humans. The lungs absorb oxygen from the air that is required for the process of respiration while on the other hand, carbon dioxide is transferred from the cells to the lungs through blood because carbondioxide gas is a waste material that is produced during respiration so it can be removed from the body with the help of lungs..
Answer:
Try answer B that should be correct
Explanation:
Answer:
Diffusion is the process of small molecules moving from a high concentrated area to a lower concentrated area. For example, in a crowded train station, when a train arrives, people move from the high concentrated area, which is the platform, and move onto the lower concentrated area, which is the trian.
Explanation:
The process of diffusion does not cost any energy, as it happens naturally, and would cost energy to go against it, like trying to go from the train into the platform costs more energy than just going with the crowd into the train. And only small molecules can do this without using energy. Large molecules, like starch, can't do this without using energy.(ATP) hopefully, this helped you, and it would mean a lot to me if you could give me brainliest!
Activation energy is required to start a chemical reaction. Activation energy is the energy needed to allow the reactant to react. Activation energy is measured in Joules (J).
Answer:
Explanation: Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
