Answer and Explanation:

Cytokines is the molecule which has the ability to communicate with the immune system cells to target on antigen by generating a response. It is mostly comprised of protein in a group along with peptides.

They are involved in the cancer treatment by production of the signalling molecules that gets involved in the method of stimulating and mobilize the immune system and thus cytokines come into the action for preventing the cancer by providing anti-inflammatory action,anti-cancer cell etc.

<u>Example</u>- In case of ovarian cancer,there is the majority of the immuno-suppressive action and thus there is production of the anti-inflammatory cytokines and thus maintain the immune system.

Explain why are the constrllations of the zodiac seen in both boston and brazil?
marishachu [46]

Answer:

Because Circumpolar constellations are constellations that never set below the horizon when seen from a particular location on Earth.

They can be seen in the night sky throughout the year, while other constellations are seasonal, visible only at certain times of year.

The term circumpolar refers to constellations and stars that are circling the north and south celestial poles without ever dipping below the horizon. All circumpolar constellations are found near the celestial poles and, due to their proximity to the poles, they never disappear from view.

The five northern constellations visible from most locations north of the equator throughout the year are Cassiopeia, Cepheus, Draco, Ursa Major, and Ursa Minor.

The three southern circumpolar constellations visible from most locations in the southern hemisphere are Carina, Centaurus, and Crux.

Other constellations are just as prominent in the sky and can be seen for most of the year, but only these eight are circumpolar.

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is inherited as an X-linked recessive allele in humans. A woman whose father
prohojiy [21]

Answer:

(a) 1/2; (b) no

Explanation:

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is an X-linked recessive disorder and the woman's father was diseased so it means that woman is a carrier of the allele but has normal phenotype. It means that she will have XXᵇ genotype.

In contrast to this, her husband is diseased so his genotype will be XᵇY.

The Punnett square diagram related to the cross is attached.

(a) Proportion of their sons expected to be G6PD is 1/2:

They both may give birth to 4 progeny with genotypes XXᵇ, XᵇXᵇ, XY and XᵇY. It means they both may have 2 sons out of which one with genotype XᵇY will be diseased while the one with genotype XY will be healthy. So the proportion of their sons having G6PD is 1/2 or 50%.

(b) If the husband were G6PD deficient, the answer will not change.

The reason behind this is that this disease is caused by an allele located in X chromosome. But father contributes only Y chromosome to his son not X chromosome. The X chromosome will affect the genotype of his daughter not son that is why answer will not change. It means they will still have 1/2 of their sons diseased.
