Im pretty sure its C because the olthers dont make sense for deforestation
<span>Mitosis in animals is the answer.</span>
<u>Answer:</u>
Effects Include:
Activates secondary messengers such as cAMP which further activates number of hormones like
- ADH: production of this hormone causes kidneys to retain more water inside body.
- GHRH: release growth factors and stimulates growth of organism.
- ACTH: produces fight or flight responses i.e rise in heart beat, rise in Blood pressure etc
- TSH: Stimulate the synthesis of Thyroid hormone and enhances the metabolism of body. In rare cases causes Goiter without the deficiency of Iodine.
- LH: Stimulate follicle maturation and formation of ovules in women.
- Calcitonin: Decreases blood calcium level by deposition calcium in bones. This effect weakens the muscles.
- Glucagon: Stimulates glycogen breakdown from liver and muscles and many more effects.
<u>Explanation:</u>
Background Knowledge:
GPCR (G Protien coupled receptors) are present inside plasma membrane in huge amount. As name suggest that these receptors are coupled with G proteins during their inactive state present inside of the cell. During their Inactive state these G proteins are bounded with GDP molecule.
Upon receiving signal molecules from outside of cell alters the shape of GPCR. These receptors also triggers change in G Protein, as a result of this GTP get attached with them. This protein further activates reaction cascades inside of the cell.
What happen if GTP cannot be hydrolyzed to GDP + Pi?
If GTP cannot hydrolyzed in to GDP + Pi than, it cannot be able to dissociate from G proteins. Cascade system doesn't stop and produces many effects on body.

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.
