Does not require previous exposure to a disease agent

Takes effect immediately

Does not last long (up to a few months)

Active Immunity is produced inside of the body, whereas passive immunity is introduced from outside of the body.

Active Immunity is from direct infection and vaccination.

Passive Immunity is from Breast milk, Injection, Mother to baby through the placenta.

Active Immunity takes effect over time (typically several weeks).

Passive Immunity takes effect immediately.

Active Immunity's length of efficacy is Long-term to lifelong.

Passive Immunity is short-term.

Which of these is a piece of evidence supporting the theory of evolution?

ycow [4]

The C option is Correct.

All the Galapagos finches exist on the same island.

Galapagos finches is a piece of evidence supporting the theory of evolution.

Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean. The group is monophyletic and originated from an ancestral species that reached the Galápagos Archipelago from Central or South America.

On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.

When blood glucose levels decrease, in between meals, during fasting or from starvation, increased levels of ________ help to in

JulijaS [17]

Answer:

B. Glucagon

Explanation:

Glucagon is a pancreatic hormone, secreted by the alpha cells of islets of Langerhans. Whenever the blood glucose level falls, glucagon is released to increase the blood glucose levels. This function of glucagon is quite opposite to the function of insulin and hence both are antagonistic hormones. Insulin reduces the blood glucose where as glucagon increases the blood glucose.

Glucoagon is large polypeptide of 29 amino acids. Since it helps in increasing the blood glucose homeostatic levels it is called as hyperglycemic hormone. It does so by stimulating certain processes such as:

- Stimulating Glycogenolysis i.e breakdown of glycogen to release more glucose from liver.

- Stimulating Gluconeogenesis i.e. synthesis of glucose from non-carbohydrate sources like proteins.

- Glucagon inhibits the process of glycogenesis i.e. synthesis of glycogen, the storage form of glucose.
