Complete question:

A pathogenic bacterium has been engulfed by a phagocytic cell as part of the innate immune response. Which of the following illustrations best represents the response?<em> Illustrations in the attached files.</em>

Answer:

Graph C best represents the response  

Explanation:

Phagocytosis occurs when the phagocyte incorporates a new solid substance, such as a bacteria. Phagocytosis is a function of specialized immunological system cells. They are capable of removing strange bodies from the immune system as a first natural defense line. The phagocyte membrane invaginates and surrounds the strange body, which is traped and included in an endocytic vesicle called a phagosome. This vesicle often fusses a lysosome which releases its enzymes into the phagosome. These enzymes are in charge of digesting or destroying the strange content. After that, the produced wastes are removed from the cell.

When does the cell have to use active transport?
kati45 [8]


The best answer is D.

In active transport, molecules move against a concentration gradient from areas of lower concentration to areas of higher concentration. This happens a lot in neurons. The membrane proteins are constantly pumping ions in and out  to get the membrane of the neuron ready to transmit electrical impulses.

In active transport , energy is required to move molecules across the cell membrane. Carrier proteins are needed for this e.g. proteins of the GLUT family which transport glucose molecules across the cell membrane. Carrier proteins are very specific. GLUT proteins will only move glucose molecules and not sodium or calcium. There are hundreds of types of carrier proteins.

A recessive allele causes phenylketonuria (PKU) when homozygote. If the frequency of the recessive allele is 0.05 in the populat
Radda [10]

Answer:

0.095

Explanation:

Phenylkentonuria is a disease caused by a recessive allele.

The frequency of the recessive allele + the frequency of the dominant allele equals 1.

The frequency of the recessive allele is q = 0.05

The frequency of the dominant allele then is p = 1  - q = 0.95

If people mate randomly, the frequency of the homozygous dominant genotype will be p², the frequency of the heterozygous genotype will be 2pq and the frequency of the homozygous recessive genotype will be q² .

2pq=2× 0.05 × 0.95

2pq=0.095

The heterozygote frequency in the population is 0.095
