The traits for blood type and Rh are the result of the presence or absence of particular on the erythrocytes.g
just olya [345]

Answer: Antigens

Explanation: The ABO system of blood grouping is based on the basis of the type of antigens that are present in the red blood cells. Erythrocytes is another name for the red blood cells. Antigens are molecules that are capable of eliciting immune response. There are two types of antigens: antigen A and B. Blood type A has only antigen A, blood type B has only antigen B, blood type AB has both antigen A and B while blood type O has no antigen (neither A nor B antigen).

Similarly, Rh trait is determined by the presence or absence of rhesus antigen in the erythrocytes. Rhesus antigen is an antigen first discovered in rhesus monkey. Rh+ indicates the presence of rhesus antigen in the red blood cells while Rh- indicates the absence of rhesus antigen in the red blood cells.

Assume that the growing polypeptide chain of amino acids being produced represents an enzyme humans use to help digest starch. T
arlik [135]

Answer:

B) nuclei of gland cells.

Explanation:

DNA carries the blueprint for the production of all the proteins including enzymes in human beings. Humans are eukaryotes and their DNA is present in the nucleus of their cells. All the cells that make the complex human body are derived from division in the zygote and therefore, are genetically identical and have the same DNA.

However, gene expression is regulated by the expression of specific genes in specific cells and at a different time of developmental stages. Amylase is the enzyme that digests starch in humans. Amylase is secreted by salivary glands. So, the nuclei of these glands would have genetic information for the synthesis of amylase.

What's the difference between human skin and the cell membrane
Hatshy [7]

Answer: Read explanation

Explanation: there’s actually no similarity at all. A cell membrane is made of phospholipids, globular proteins, glycolipids, glycoproteins, and cholesterol, and has passages that serve explicitly for passive and active transport of materials through it.

The skin is made of cells and dead keratin and serves as much as possible to prevent most substances from moving through it. It’s “designed” for toughness and distensibility, not for selective permeability.

All in all, the difference is that a cell membrane is explicitly and only for the passing and transport of materials through it, and the skin in the skin is made to be tough and durable, almost the opposite of a cell membrane.
