Answer:
d. an immediate increase in the concentration of antibodies, followed by a slow decline.
Explanation:
The Primary Immune Response is mediated by antibodies, which are gamma globulin proteins formed by plasma cells (B lymphocytes). Plasmocyte is a differentiated B lymphocyte capable of actively secreting antibodies.
Antibodies are produced with the main function of neutralizing and eliminating an antigen that stimulated their production. This elimination process is done in various ways through complement fixation, opsionization, anaphylactic reaction (mast cell degranulation), substance neutralization, agglutination, etc.
To neutralize the antigen, the primary immune response promotes an immediate increase in antibody concentration. This is usually a quick process. This concentration usually begins to decline in a slow process, but it will vary depending on the antigen.
The order of steps for the digestion of proteins will be;
In mechanical digestion, the teeth grind food and break it in to smaller parts.
Churning and the enzyme pepsin break down protein in the stomach
The pancreas releases enzymes trypsin and chymotrypsin
Tryspsin and chymotrypsin act on the proteins to break them down in the duodenum
Amino acids are absorbed by the capillaries in the Jejunum and lastly
The amino acids enter the blood stream and are circulated throughout the body.
Answer:
The incorrect association is Electron transport chain:acetyl-CoA.
Explanation:
Chemiosmosis deals with synthesis of ATP by the catalytic activity of ATP synthase so this association is correct.
During glycolysis Glucose 6 phosphate is generated as the first product of this catabolic pathway so this association is correct.
Oxaloacetic acid is the end product of krebs cycle so this association is correct .
But electron transport chain has no relation with acetyl-CoA so this association is incorrect
Energy flows through ecosystems in <u>one</u> direction, typically from the <u>sun</u>, through photosynthetic organisms or <u>green plants with algae</u>, to <u>herbivores </u>to carnivores and decomposers.
