Answer:
Mass extinctions, like the one that killed the non-bird dinosaurs, leave behind a host of empty niches — unoccupied ecological real estate. The upshot of all these processes is that mass extinctions tend to be followed by periods of rapid diversification and adaptive radiation.
Explanation:
The answer would be C 90% sure
Ans.
Meiosis involves a type of cell division in sexually reproducing organisms that results in formation of four daughter cells from a single parent cell, having half of the genetic material as in parent cell. Meiosis is divided into meiosis I and meiosis II.
In gamete forming cells of humans are diploid cells and have 23 pairs of chromosomes (or 46 chromosomes). Each gamete forming mother cell undergoes meiotic division to form haploid daughter cells or gametes, each with 23 chromosomes.
Thus, the correct answer is 'twenty-three' as there are 23 chromosomes present in human sex cells at the end of meiosis II.
I just took the test. Edgen says the answer is c. suffocation.
