Antibodies are produced when the body is exposed to
erica [24]


Antibodies are produced when the body is exposed to antigens.

During an initial encounter with a foreign antigen, the body's immune system namely the adaptive arm of the immune system, produces memory cells, a group of special lymphocytes that retain and store memory of the antigen.

On a second encounter with the same kind of antigen, the immune system "remembers" the antigen and mounts a rapid, specific and vigorous immune response against the antigen. This response includes the production of massive amounts of antibodies very specific to the antigen.

The antibodies effectively neutralize the antigen and facilitate its destruction.

In the spleen, ___________ from red blood cells is broken down to form (unconjugated) bilirubin. Unconjugated bilirubin is insol
adelina 88 [10]

Answer:

Haemoglobin; liver; binds; stored; bile duct; small intestine; lipids.

Explanation:

Serology can be defined as the study of blood and the reactions between antibodies and antigens in the blood.

In Biology, blood pH can be defined as a measure of the hydrogen ion (H¯) concentration of blood i.e the level of alkalinity or acidity of blood.

Basically, the normal blood pH of a human being should be between 7.35 and 7.45.

Hence, one of the ways in which the body regulates blood pH is with proteins. Proteins help regulate blood pH by accepting and releasing hydrogen ions. Typically, when the blood pH falls, the hydrogen ions (H¯) are accepted (absorbed) while hydrogen ions are released when the blood pH rises.

For example, a protein such as haemoglobin which makes up a composition of the red blood cells, binds an amount of acid required to regulate blood pH.

In the spleen, haemoglobin from red blood cells is broken down to form (unconjugated) bilirubin. Unconjugated bilirubin is insoluble in blood plasma so binds to albumens in the blood and is sent to the liver. Bilirubin binds with glucuronic acid to form conjugated bilirubin. It forms part of the bile, which is stored in the gall bladder. Food in the gut stimulates gall bladder contraction and the bile passes down the bile duct to the small intestine, where it aids in the digestion of lipids.

The thickest part of the crust occurs in _____.
lana [24]

Answer:

Option (3)

Explanation:

The continental crust is usually thick because it has an average thickness of about 35-40 km. In the high mountain ranges, it is the thickest, forming about 80 km on an average. These are formed when two continental plates form a sandwich pattern by sharing a convergent type of plate boundary.

For example, the thickest part of the crust is the Mt. Everest which lies in the great Himalayan range, which has started to form about 50 million years back. It is geologically the most recent mountain range.

The older mountains are continuously eroded in the geological past, as a result of which the height of the mountains is affected.

Thus, the correct answer is option (3).
