Prokaryotes are single-celled organisms of the domains Bacteria and Archaea. All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles. Many also have polysaccharide capsules. Prokaryotic cells range in diameter from 0.1–5.0 µm.
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions. Eukaryotic cells tend to be 10 to 100 times the size of prokaryotic cells.
<span>Generally speaking ,karyotyping, can determine the gender of an individual and the presence/
absence of chromosomal defects which could lead to disabilities ,diseases and
problems in the person’s growth and development, as well as the probability
which it could be passed on to the offspring. This is done through the evaluation
of the number, shape, size, and position of the chromosomes within a body cell. </span>
ANSWER:
After the volcanic eruption,lava cools down,vegetation reappears and microscopic plants grow,then the macroscopic plants and animals come at that place,then gradually the whole system builds and ecosystem recovers.
EXPLANATION:
Biodiversity means diverse population of plants and animals. After the volcanic eruption,both plants and animals donot exist because of high temperature and not suitable environment. With the passage of the time, the lava cools down and vegetation stars reappearing. First of all lichens and microscopic plants and after that macroscopic plants and animals come at that place.Thus suitable conditions reappear and gradually the whole ecosystem recovers.
According to the evolutionary theory, over the history of the human species, aggressive males have had the greatest impact on the gene pool. It is natural selection.
<h3>What is evolution?</h3>
The term evolution refers to descendence with modification, which mainly occurs due to natural selection.
Natural selection refers to the differential process of survival and reproduction of the fittest individuals in a population.
Aggressivity may thus represent an adaptive feature (i.e., an adaptive trait) in human evolution.

Answer:
The correct answer is A. two daughter cells with identical chromosomes
Explanation:
Mitosis is also known as equation division because in mitosis one cell divide into two daughter cells having identical chromosomes. In higher eukaryotes, mitosis helps in the growth of the organisms by increasing cell number. It also helps in replacing the damaged and old cells in multi-cellular organisms.
Some single-cell organisms use mitosis to reproduce. In mitosis first, the genetic material and other organelles get double and then the cell gets separated into two daughter cells having identical genetic material and other organelles. So in mitosis genetically identical cells are produced. So the right answer is A.
