Answer:
A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular. Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall.
Answer:
A) %
B) %
Explanation:
A) Given
Frequency of individuals in the population having recessive phenotypes %
Frequency of individuals in the population having recessive phenotypes is represented by
Thus frequency of recessive genes is equal to
frequency of dominant genes is equal to
Now,
% of genes exist in the heterozygous condition
B.
Frequency of individuals in the population having recessive phenotypes %
Frequency of individuals in the population having recessive phenotypes is represented by
Thus frequency of recessive genes is equal to
frequency of dominant genes is equal to
Now,
% of genes exist in the heterozygous condition
Answer:
Allows to give rise to different organs.
Explanation:
Since all the cells in our body have developed from a single cell, "the egg or ovum fertilized by a sperm", all of them are identical, that is, they have exactly the same instructions, but depending on the organ they form part, they will use only part of the information or another. This is known as cell specialization.
Thus, the nerve cells possess the information necessary to form hair and the cells that form hair possess the information necessary to form nerves. However, once specialized, nerve cells will form nerve tissue and hair cells will form hair.
In this way, being different recipes, the cells give rise to different organs.

<span>This cell division is primarily called the mitotic process -mitosis.
Mitosis
occurs more in your body since it changes, modifies and requires cell
division at maximum rate in many useful situations with the stand to a
particular system and organ. Mitosis and meiosis are simply cell
division processes that occurs differently, they're characteristically
divergent from each other according to their function and structure.
Mitosis is the cell division that happens in all cells in the human body
except sperm and egg cells. They produce diploid cells. <span>Take
for instance your integumentary system, layer of the skin in which your
stratum basale always produces new epithelial cells (via mitosis) to
take over until the outer layer, called stratum corneum (a continous
replaced dead cells in this layer).<span> </span></span></span>
