Answer:
The exponential growth model shows a characteristic curve which is J-shaped while the logistic grown model shows a characteristic curve which is S-shaped. The exponential growth model is applicable to any population which doesn’t have a limit for growth. The logistic growth model is applicable to any population which comes to a carrying capacity.
Explanation:
The answer is autosomes.
<span>In
a human diploid somatic cell (2n), there are 22 chromosomes
present in two copies and 1 pair of sex chromosomes. This means
there are 23 pairs of chromosomes - 22 pairs of autosomes and 1
pair of sex chromosomes. There are in total 46 chromosomes (23 pairs
in 2 copies: 23 × 2 = 46).</span>
<u>Answer:</u> A) once, during interphase I
<u>Explanation:</u>
Meiosis is a form of eukaryotic cell division which results in four daughter cells, each of which has half the number of chromosomes as their parent cell.
There are two major phases that a cell goes through during meiosis. About 80% of of the total cell division is interphase.
Its during interphase 1 that the cell replicates its chromosomes, where each of the chromosome has a couple of sister chromatids.
Also, the chromosomes replicate only once.
