Hemoglobin is a water-soluble, globular protein made of 2 alpha-hemoglobin and 2 beta-hemoglobin polypeptide chains. hemoglobin is present in large amounts in the cytoplasm of red blood cells. where in the cell are the alpha- and beta-hemoglobin proteins made? a. in the cytoplasm, by free cytoplasmic ribosomesb. by ribosomes docked to the rough erc. by ribosomes docked to the nuclear enveloped. by ribosomes docked to the plasma membranee. by ribosomes in the mitochondria

The answer is A

Explanation:

There are certain types of proteins that need to be sinthesized in the rough ERC in order to reach its final destination. These proteins are:

- Proteins that need to be exported from the cell.

- Proteins that need to be docked to either endomembranes or the plasma membrane.

- Hydrolytic lysosomal enzimes.

- Proteins that have a function in the lumen of certain organelles such as the endoplasmic reticulum, golgi or the nuclear envelope.

Hemoglobin doesn't fit in any of these cateogories, given that it is a cytoplasmic protein. Therefore, its synthesis begins and ends in the cytoplasm, where the protein performs its function.

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.

explanation:

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
