Answer:
glycoproteins
Explanation:
Glycoproteins are the proteins to which carbohydrates are attached. The glycocalyx is the covering made up of sugar residues of glycoproteins and glycolipids and is associated with the plasma membrane.
Glycoproteins of animal cells are exposed to the extracellular surface and are involved in cell recognition. They serve as a tag by which the cells are identified. For example, the glycoproteins of bacterial cells serve as antigens that are recognized by the cells of the immune system of humans. However, these cells recognize the glycoproteins present on the cells of own body as "Self". Likewise, specific glycoproteins present on the surface of RBCs determine the blood type as A, B, AB or O.
I think it is called the anemone
Answer:
By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition.
I learned this it the nuclear without that they would not have nutrients
It’s a facilitated diffusion!
Facilitated diffusion= high to low concentration= has a protein channel
