Answer: The correct answer is option (A) i. e. Prokaryotic cells do not have a nucleus in their cell but eukaryotic cells have nucleus in the cell.

The main difference between prokaryotic and eukaryotic cell is that prokaryotic cells have no nucleus in their cell while eukaryotic cells have nucleus present in the center of their cell. In prokaryotic cells, DNA or genetic material is present in the place of nucleus in the center of the cell.

Why is it critical that equal amounts of DNA are shared between homologous chromosomes?
harina [27]
<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>

Compare the hygiene allergies and asthma?
Vadim26 [7]

Answer:

According to the “hygiene hypothesis,” the problem with extremely clean environments is that they fail to provide the necessary exposure to germs required to “educate” the immune system so it can learn to launch its defense responses to infectious organisms. Instead, its defense responses end up being so inadequate that they actually contribute to the development of asthma.
