Archaea I think this is the right choice
Answer:
F1 Females - all wild type
F1 Males - all wild type
F2 Females - - all wild type
F2 Males - 1/2 wild type, 1/2 vermilion
Explanation:
The wild-type allele (Xᵛ⁺) is dominant over vermilion (Xᵛ), which is a sex-linked trait.
Female flies have two X chromosomes, male flies have one X and one Y chromosome.
A homozygous wild-type female fly (Xᵛ⁺Xᵛ⁺) is mated with a vermilion male fly (XᵛY).
The female parent can only produce Xᵛ⁺ gametes.
The male parent can produce either Xᵛ or Y gametes.
When gametes from both parents fuse, the F1 offspring will have the genotypes Xᵛ⁺Xᵛ (females with wild type eyes) and Xᵛ⁺Y (males with wild type eyes).
The F1 females can produce Xᵛ⁺ and Xᵛ gametes. The F1 males can produce Xᵛ⁺ and Y gametes.
When the F1 individuals interbreed, the gametes combine to give rise to the F2 offspring. The possible combination of gametes that will give the different genotypes and phenotypes in the F2 are:
- Xᵛ⁺Xᵛ⁺ females with wild type eyes
- Xᵛ⁺ Y males with wild type eyes
- Xᵛ Xᵛ⁺ females with wild type eyes
- Xᵛ Y males with vermilion eyes

Answer:
The correct answer is option C. "Increase in temperature â Increased rate of evaporation â More moisture in air".
Explanation:
Thermohaline circulation, also known as Global Ocean Conveyor, is the way that vast masses of water are moved in the ocean controlled by horizontal differences in temperature and salinity. This movement is usually slow, and serves as a way to transport heat, nutrients and other materials trough the ocean. When thermohaline circulation gets unusually slower, the heat is not efficiently transported. This results in an increase in the overall temperature, which increases the rate of evaporation, increasing the level of moisture in air and finally resulting in more frequent severe storms.
