Systematics is the study of the units of biodiversity. Systematics differs from ecology in that the latter is concerned with the interactions of individuals (and therefore species) in a particular time.
Answer:
The human body is modified with the environmental needs.
Explanation:
A human body is exposed to its environment. There are body enzymes which reacts together to adjust in a certain environment. People living in polluted area are used to of that pollution. They drink polluted water, breathe in polluted air and are still alive but when someone from other area visits such environment, they fall ill and cannot survive in that polluted environment. This is entirely because their body refuses to accept the new changes in environment quickly.

Hello, I figured your question was missing its answers so I went online to find them. Here they are:
No visible cytoplasmic granules are present in ________.
A) basophils
B) monocytes
C) eosinophils
D) neutrophils
Answer:
The correct answer is: B) monocytes.
Explanation:
<u>White blood cells can be divided into granular and agranular.</u> Granular leukocytes (WBC) have granules that contain enzymes in their cytoplasm (the enzymes are used in the immune and inflammatory responses). <u>Agranular leukocytes</u><u> do not have cytoplasmic granules</u>.
<u>The granular leukocytes are 3: basophils, eosinophils, and neutrophils</u>.
<u>The</u><u> agranular</u><u> leukocytes are: </u><u>monocytes</u><u> and lymphocytes</u>.
Monocytes are very large cells with the important function of phagocytosis: this makes them capable of eating pathogens and old blood cells. When arriving at a tissue outside of the blood, they differentiate to macrophages with special features to perform in that tissue. They make up <u>2 to 8 percent of all leukocytes</u>. Monocytes and macrophages are also antigen-presenting cells (APCs): when needed, they can present antigens to other white blood cells in order to mediate the immune response.
<span>Correct answer:
<span>Diffusion is the movement of particles from a high to low concentration, while osmosis is the movement of water from a high particle concentration to a low particle concentration.
</span></span><span>This movement of molecules occurs due to a thermal motion. Diffusion normally occurs between two compartments having difference in concentration. In case of fluid it moves from the region of higher concentration to the region of concentration until a balance is reached. The process of diffusion is very important for the humans as well. The oxygen that humans breathe in gets diffused with the blood.</span><span><span>
