Answer:
23
Explanation:
After mitosis two identical cells are created with the same original number of chromosomes; 46. Haploid cells that are generated through meiosis, such as egg and sperm, only have 23 chromosomes, because, remember, meiosis is a "reduction division."
Answer:
Selective breeding.
Explanation:
Both are fairly long processes, however, the measurement for this is not just the duration to obtain the target, but also the exact target obtained. In natural selection, the duration may be faster than selective breeding in obtaining a change, but the determined change may not be the one that is sought out for. It may have a small chance, but it is not guaranteed. In selective breeding, on the other hand, the destination is determined, and all steps work towards the objective. So in a sense, selective breeding has the greater percentage chance of being the shorter process.

Answer:
a) b + i = d + e
b) b + i < d + e
c) b + i > d + e
Explanation:
Data provided in the question:
b = birth
d = deaths
i = immigration
e = emigration
Now,
a) a population in equilibrium
this means increase in population is equal to decrease in population
i.e
b + i = d + e
b) b) a declining population
this means increase in population is less than decrease in population
i.e
b + i < d + e
c) an increasing population
this means increase in population is increase in decrease in population
i.e
b + i > d + e
The question is referring to primary succession, which begins with the colonization of living organisms in an area that hasn't had any living organisms before.
This kind of succession begins with microorganisms, and plants such as lichens and mosses.
Given that a rock outcrop is a terrestrial environment, lichens (C) are most likely to be the firsts organisms.
