Answer:
ATP gives free energy that the cell can use for energy using processes in the cell
Explanation:
sometimes ATP is necessary for the transportation of nutrients in the human body. ATP gives the cells energy to do for example endocytosis or exocytosis. (actively absorbing nutrients or emitting nutrients)
Crossing over contributes to genetic variation by exchanging chromosomal segments between non-sister chromatids of homologous chromosomes.
What is crossing over?
- Crossing over is the exchange and recombination of genetic components between the homologous chromosomes.
- This occurs in the pachytene stage of the meiosis-1 of the meiotic division.
- Crossing over occurs with the help of an enzyme and the enzyme responsible for crossing over is called Recombinase.
Thus, crossing over contributes to genetic variation by exchanging chromosomal segments between non-sister chromatids of the homologous chromosomes.

The correct answer is option (A) the fossil record.
Coordinated stasis refers to the stasis or the no evolutionary changes in the organisms for millions of years, which is followed by extinction and formation of the new species.
Fossil records have the evidence of ecological and evolutionary stability in the species over a long period of geological time scale separated by intervals of abrupt change. The best example of this being the animals of the Middle Devonian Hamilton group. Thus, fossil record is the only source of record showing this long period of stasis and separated by periods of abrupt changes in the species due to environmental pressures.
Even with treatment, up to 1 in 3 people with necrotizing fasciitis die from the infection. Six out of every 10 people who get both necrotizing fasciitis and streptococcal toxic shock syndrome at the same time die from their infection
