Answer:

The maximum members of the population of species that can be supported by the environment on the basis of the existence of resources is considered as the carrying capacity. It is not easy to determine the carrying capacity for human beings on the planet Earth, as the population of human beings is increasing exponentially on the planet Earth. Due to their intelligence and tendency to resolve the issues associated with the lack of resources, it is not easy to find the carrying capacity of human beings.

While taking a walk around the neighborhood, a student walks into a tree branch and cuts their arm. Which explanation BEST descr
DaniilM [7]

Answer:

C

Explanation:

First off, humans are considered animals, and since animal cells don't have chloroplasts, A and D are immediately incorrect. B is incorrect because lysosomes eject enzymes that digest materials in the cell, and to heal skin, you dont need to digest anything/ use enzymes to get rid if materials. That means the answer is C. The nucleus is the control center for the cell, so it tells the cell what to do. The mitochondria creates energy for the cell, and since it takes energy to heal, this answer is correct. (Tip- I find that using process of elimination in biology questions helps a lot.) Good luck!
