Answer:
A population is a group of organisms of the same species, in the same place
A species is a group of organisms that are genetically similar
Explanation:
I like to remember it with humans.
Humans (homo sapiens) are a species. We are all genetically similar and can share genetic material by reproduction.
In a city, a lot of humans are together and that is a population of humans

Phagocytosis is a process where cells can engulf bacteria or food.
<h3>What is phagocytosis?</h3>
Phagocytosis is a process in which cells such as macrophages surround and engulf some type of substance that the body wants to eliminate. Phagocytosis is a type of <em>endocytoses</em>. It is a process that the immune system uses to eliminate pathogens or cellular debris, finishing the material being digested by the cell, seen in processes such as infection.
We also see it in <em>apoptosis</em>, where the macrophages are going to ingest the remains of the apoptotic cell for the elimination of their cellular remains.
Therefore, we can confirm that phagocytosis is a process where cells can engulf bacteria or food.

Answer:
The correct option is A. The oxygen atoms diffuse through the atmosphere and are inhaled by animals.
Explanation:
Photosynthesis can be described as a process in which plants use the light from sun to convert carbon dioxide and water into glucose. Oxygen is made as a by-product of this reaction. This oxygen is released into the atmosphere by the plants through the mechanism of diffusion.
The oxygen released into the atmosphere is taken up by animals. Animals utilize this oxygen for the process of respiration.
The process of respiration and photosynthesis are opposite to each other.
Explanation:
the process of making food with the help of Sunlight, water and mineral, carbon dioxide etc. is called photosynthesis.
