Answer:

Crossing over produces genetic variations in daughter cells, consequently leading to genetically dissimilar offspring.

Explanation:

Crossing Over:

  • A process that occurs during the Prophase 1 of meiosis 1, a type of cell division that takes place in germ cells (reproductive cells) to produce gametes for reproduction.
  • Crossing over, by definition, is the exchange of chromosomal segments between non-sister chromatids of chromosomes.This occurs through a process called homologous recombination.
  • <u>Crossing over produces a variety of gametes with characteristics different from the parents.</u>
  • In terms of evolution, this process introduces genetic variations that can help the organism better adapt to its environment.

the skull forms a solid sheet of protection and the ribs form a cage. why do you think the rib cage is not a solid sheet like th
Sergeeva-Olga [200]

I think the the ribs are not a solid sheet because they need to be able to expand so the lungs can get an adequate amount of air in the lungs. The brain just needs to be protected and doesn’t need to expand so it’s a solid sheet. The skull seems to be the better protector at first because the ribs can break and puncture a lung, harming your breathing but if you do hit your head your brain can start swelling and the skull doesn’t allow any room for expansion. Head injuries are much more dangerous, especially if the brain starts swelling. Rib injuries seem much simpler to fix and less dangerous.
