B. Cell membrane
Remember cell membrane is the structure aka “wall of the house” is the clear boundary between the cells internal and external environments:))
Hope this helps
Answer:
Suffling of genetic material increases genetic variation in offspring which is important for evolution.
Explanation:
Genetic shuffling or genetic recombination helps in the formation of new trait combinations which increase the genetic variation in the population and this genetic variation is very much important for the evolution of species.
In sexual reproduction, the genetic shuffling occurs during the formation of gametes when the two homologous chromosomes exchange their genetic material with each other. This increase variation in gametes.
Fusion of two different gametes in sexual reproduction also helps in increasing the genetic variation in the offspring.
I would select A because cells have to divide into smaller cells depending on where they are.
I would say the second answers, growth. This is because we need the nutrients and vitamins from food to help us grow, and keep us healthy.
Explanation:
the most common gas in the atmosphere is nitrogen and oxygen followed by CO2 etc...
