Answer:
A. The same species of organisms from one geographic area make up a population.
Explanation:
- Population refers to a group of organisms of the same species living in the same geographical area at the same time. Therefore organisms of similar species make up a population.
- Several populations in turn make up a community. This explains why a community refers to groups of different species living in the same geographical area or an ecosystem.
The correct answer is this one: "C) Nnew = Nold + 2." A student is studying a process in which a diploid cell becomes haploid. The CORRECT mathematical model for the process if Nnew is the number of chromosomes in the haploid cell and Nold is the number of chromosomes in the diploid cell is this: <span>new = Nold + 2
</span>
Here are the choices.
<span>A)
Nnew = 2·Nold
B)
Nnew =
Nold
2
C)
Nnew = Nold + 2
D)
Nnew = Nold × 2</span>
