Answer:
Burning fossil fuels, and decomposition of dead organisms
Explanation:
I am pretty sure that the answer is carbon dioxide.
Answer:
It controls what the cells are doing and carries your genes. It acts as the brain of a cell.

Answer:
<u> Option-(B):</u> For most members of our micro-biota, our body provides their environment, or space to live. They, in turn, have no effect on us. This is an example of commensalism.
Explanation:
- There are different forms and levels of associations which are formed between the different species and they are characterized differently based upon there outcome in a given region or space in which both the living beings interacts, as the result may be harmful or beneficial for either one of them or any number of individuals which are greatly affected by its presence.
- But, commensalism provides the shelter, food resources, and a place to grown for one being while the other is neither harmed nor is benefited due to the following association that has taken place between the living beings.
Q1. The main difference between flagella and pili in a prokaryotic cell is their length. Flagella are long and thin, whip-like appendages that extend from the interior of the prokaryotic cell. There are much fewer flagella than pili on the prokaryotic cell. Pili are short and hallow, hair-like appendages from the surface of the cell. They do not extend from the interior of the cell.
Flagella are made of protein flagellin while pili are made of protein pilin.
Flagella can be found in both Gram+ and Gram- bacteria while pili can be found only in Gram- bacteria.
A function of flagella is motility. Pili can perform motility but are rather responsible for attachment and genetic exchange.
Q2. Photoautotrophic organisms contain pigments that help them absorb the light of certain wavelength so they can make their own food (because they are autotrophs) in the process of photosynthesis. There are different types of pigments and it is hard to say if they are similar to chlorophyll or not. Because they do the same function, but also they differ in chemical composition.
