Answer:
8 chromatids
Explanation:
Meiosis is a kind of division that produces offsprings with their chromosomal number reduced by half. It occurs in a two-step division i.e. meiosis I and II. In meiosis I, homologous chromosomes (similar but non-identical chromosomes received from each parent) separate.
Hence, in this case involving a somatic cell with 16 chromatids. This means that it possesses 8 chromosomes since each chromosome comprises of two sister chromatids. During Anaphase 1 of meiosis 1, each homologous chromosome separate into opposite poles of the cell, and after cytokinesis, there would be 4 chromosomes (8 chromatids) in each cell.
These chromatids will separate in meiosis II.
Answer:
The correct answer is- C. allows new species to occupy different habitats.
Explanation:
Adaptive evolution is a type of evolution that allows the generation of new species from an ancestral species. This evolution occurs mainly due to the separation of habitat between two populations of species.
So when some members of ancestral species get new habitat which is different in ways like in food availability, food type, environment, etc then this isolated population adapts to the new environment by doing changes in their gene which results and the development of new species. So the correct answer is C.
The answer is B: it creates offspring from parents
<span>I think you might be asking about the 3 different osmotic conditions a cell might find itself in. Isotonic is the normal cell environment where water moves in and out of the cell freely and equally in both directions. It is in osmotic equilibrium so to speak. The concentration of water and solutes is equal on both sides of the cello membrane. In a hypotonic solution the cell will gain water and swell up -...</span>
