<span>Homologous chromosomes are chromosomes of equal length, size, and of corresponding genetic material. If, during meiosis, these chromosomes divide improperly, when they are re-combined with the opposite sex's portion, they will combine improperly. The unequal distribution of genetic material in reproduction will eventually create what's call an aneuploid germ cell: this germ cell results in dead zygotes, which leads to a miscarriage or spontaneous abortion in about 25 percent of all conceptions. So we see that it is imperative the genetic material of these chromosomes be exactly where it is supposed to be: so that it can combine perfectly with its compliment.</span>
White blood cells ( lymphocytes is correct though)
Answer:
30meter per second
Explanation:
Given that
Distance = 3000 meters
Time = 100seconds
Speed = distance /time
Substituting the values
Speed = 3000/100
Speed = 30meter per second
The average speed needed to cover the travelling will be 30meter per second.
The correct is D.
Disappear from a population.
Hope this helps!
