Lymph is the fluid carrying the white blood cells. It protects the body against many infections. Lymph nodes are the small areas throughout the body and abundantly present in the neck, arm pits and groin areas. They contain the lymphocytes that fight infections. These nodes filter out harmful organisms and abnormal cells before the lymph reaches the blood. A swollen lymph node is an indication of an infection. It can be a minor infection like the ear infection, strep infection or serious medical problems like the lymphomas, other cancers and AIDS. During pharyngitis which is the inflammation of the pharynx, the lymph nodes swell with the T lymphocytes due to the immune response.

The human genome is the basic genetic code, or blueprint, for the transfer of traits from parents to offspring through – . Study
Mars2501 [29]

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of options but the complete question is in the attached picture below.

The human genome is the basic genetic code, or blueprint, for the transfer of traits from parents to offspring through -hereditary transmission- . Studying this code -has revealed- ways to partially correct genetic defects after birth. It is already clear that behavior is rarely controlled by -a single gene- . Rather, almost all behavior involves -multiple genes- , and often specific -environmental- factors influence how genes are expressed.

It would be noted that some of the options were not chosen at all, this is because this question focuses on genes and it's expression. "Nurture and education" and "psychological" are not factors that actually affect gene expression. Also, studying genetic codes has already revealed partial ways to correct genetic defects and hence it would be wrong to choose "may in time reveal". For instance, there are procedures used to identify genetic defects in the spermatozoa of a male which can be screened out and the "good" sperm used to fertilize an egg in-vitro.

How does cytokinesis differ in animal and plant cells? What is it called in each? Use a picture to help your explanation.
Amiraneli [1.4K]

Answer:Plants - cell wall forms.

Animals - cleavage furrow forms

Explanation:Cytokinesis occurs in mitosis and meiosis for both plant and animal cells. The ultimate objective is to divide the parent cell into daughter cells.

In plants , this occurs when a cell wall forms in between the daughter cells.

In animals , this occurs when a cleavage furrow forms. This pinches the cell in half.
