Well, we cause pollution from not recycling.
The answer is D. A is obviously incorrect because they just listed these many different cells that are grouped together. B is incorrect because not only similar cells are grouped together, and they often perform different functions. C is incorrect because the functions are never unrelated, they are usually interdependent with each other.
Answer:
Processing and storing food.
Explanation:
The coelom is the hollow structure formed in the organisms filled with the coelom fluid. The coelom is formed during embryogenesis which may be lined by the mesodermal layer or not.
The formation of coelom serves many functions in different organisms like it allows the internal movement of the organs in the body, allows the independent movement of the digestive tract, the fluid present in the cavity acts as a hydrostatic skeleton in the lower organism and cushions the internal organs.
The function that is not performed by the coelom is that it is not involved in the processing and storing food in organisms.
Thus, Processing and storing food is correct.
Decomposers are important because they break down dead plants and animals, and they're very important to the ecosystem, because if they weren't in our ecosystem them the plants wouldn't get the essential nutrients they need to survive.
Certain genes that allow for a certain thing to happen are turned on or turned off as needed. A brain cell may have the gene needed to send electrical pulses to other brain cells or other parts of the body, whereas a heart cell may have the genes that allow it to contract to pump blood. (I don't know if those are real genes, but hopefully you get the idea)
