Biogeographical patterns provide clues about how species are related to each other. The fossil record, though incomplete, provides information about what species existed at particular times of Earth's history.
Microbes are everywhere. They populate the air, the water, the soil, and have even evolved intimate relationships with plants and animals.
The human body is inhabited by millions of tiny living organisms, which, all together, are called the human microbiota. Bacteria are microbes found on the skin, in the nose, mouth, and especially in the gut. We acquire these bacteria during birth and the first years of life, and they live with us throughout our lives
On the other hand, areas of the body such as the brain, the circulatory system and the lungs are intended to remain sterile (microbe free). The human body provides many unique environments for different bacterial communities to live.
Answer:
Input ingredients = water, carbon dioxide, energy from the sun
Output ingredients = glucose, oxygen
Explanation:
Photosynthesis involves the production of carbohydrates from inorganic products. The chemical equation for the process is represented below:
Water and carbon dioxide molecules combine in the presence of sunlight radiation to give glucose and oxygen molecules.
Input ingredients = water, carbon dioxide, sunlight
Output ingredients = glucose, oxygen
Answer:
The low pH of the lysosome is maintained by membrane proteins that pump protons (H + ions ) from the cytosol into the lysosome. ... Although it may seem dangerous for cells to contain enzymes that can digest most biological molecules, the contents of the cell are doubly protected from the digestive enzymes of the lysosome.

Explanation:
Answer:
C.) Disruptive selection
Explanation:
Disruptive selection is also called as diversifying selection. Here, two or more extreme phenotypes are preferred over the intermediate phenotype. Since more than one phenotype is preferred here, the genetic diversity of the population increases over generations.
For example, in lobsters alpha males are able to successfully mate by using force. Smaller males can also sneak in alpha males's territory and successfully mate. Hence, both alpha males and small males will be preferred over medium sized males in lobsters increasing the overall genetic diversity of population.
