Which is colder the east or west coast of southern Africa.why<br><br>​
Aneli [31]

West Coast water temperatures are much lower than those along the East Coast. ... This means Atlantic waters travel to the U.S. East Coast from the south and are relatively warm compared with West Coast Pacific waters that arrive from the north out of the chilly Gulf of Alaska.

The air above the cold Benguela current and upwelling region along the west coast is relatively dry and cold, contributing to the dry climate of the west coast. Moist air from the warm Indian Ocean and Agulhas Current is frequently transported into eastern South Africa by easterly winds.

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>

In a population of Mendel's garden peas, the frequency of the dominant A (yellow flower) allele is 80%. Let p represent the freq
k0ka [10]

Answer:

C) 64% AA, 32% Aa, 4% aa

Explanation:

The frequency of dominant allele A is = 80% = 0.8

Since the population is in Hardy-Weinberg equilibrium, p+ q =  1

Here, p= frequency of dominant allele

q = frequency of recessive allele

Given, p= 0.8

So, q = 1-p = 1-0.8= 0.2

Frequency of genotype AA = p2 = 0.8 x 0.8 = 0.64 = 64%

Frequency of genotype aa = q2 = 0.2 x 0.2 = 0.04 = 4%

Frequency of genotype Aa = 2pq = 2 x 0.8 x 0.2 = 0.32 = 32%
