A small percentage of the body’s iron supply circulates freely in the blood, bound to a protein called transferrin. Transferrin
german

Answer:

What best describes how transferrin is transported through the erythrocyte plasma membrane is receptor-mediated endocytosis.

Explanation:

The incorporation of transferrin across the erythrocyte membrane depends on a transferrin receptor expressed on the surface of the membrane. The specific receptor recognizes the presence of iron-charged transferrin, transferin diferrica, incorporating it into the cell by endocytosis. Once in the cytoplasm, the iron is dissociated from the transferrin.

Free transferrin is called apotransferrin. The transferrin receptor has a high affinity for transferrin di-ferrica, which facilitates its incorporation by endocytosis, and the release of apotransferrin into the extracellular space.

The other options are not correct because:

<em>     A. </em><u><em>Exocytosis</em></u><em> implies the exit of substances from the cell.</em>

<em>     B. </em><u><em>Pinocytosis</em></u><em> involves the invagination of the membrane to incorporate soluble substances into the cell.</em>

<em>     C. </em><u><em>Phagocytosis</em></u><em> is the incorporation of solid substances by invagination of the membrane.</em>

A woman heterozygous for polydactyly (extra fingers and toes), a dominant trait, is married to a normal man. What is the probabi
Feliz [49]

Answer:

The correct answer is -50%

Explanation:

Polydactyly is a dominant trait where a person gets an extra finger or toes the dominant allele is represented by P = allele for polydactyly, and the recessive allele represented by p = normal allele

So, the heterozygous woman will be - Pp & the normal man will be - pp.  The presence of one allele of polydactyly will be able to show its effect as it is dominant.

Cross between heterozygous woman & normal man:

Gametes:

   P                              p

p Pp (Show polydactyly) pp (Normal phenotype)

p Pp (Show polydactyly) pp (Normal phenotype)

From the above Punnett square, the probability of an offspring that has extra fingers or toes will be 1/2 or 50%.

How are primary and secondary succession the same?
ruslelena [56]
They are both the same and different in some way. But, if you're looking for the similarities, they both "rebulid" the environment that has been damaged by nature itself or by humans. The only difference is Primary succession takes longer than secondary succession. I hope this helped! :-)
