Is it ever possible for two parents to have a colorblind daughter but not a color blind son? Explain.
Anna [14]
Yes, it’s possible. The genetic that they give out to their children depends. If the parents gives out the genes for colorblind for the daughter but not the son, it’s possible.

It’s just like having a child with disabilities and another child that is perfectly healthy.

What were the two driving forces that drove the evolution in the variation of skin color
yarga [219]

Answer:

The correct answer is: geography and UV radiation.

Explanation:

Skin variation occurred thanks to evolution, and was driven as a consequence of the geographical location of different populations of humans.

The humans that lived in hot and sunny places, closer to the equator, where much more exposed to the sun's ultraviolet radiation. In order to survive the amount of UV lights that they were exposed to, new humans in those regions were being born with a darker skin tone, which was rich in melanin (a brown pigment that protects us from the sun radiation).

Contrary to these humans that lived in the tropical areas, the humans that populated the areas that were closer to the poles, developed much lighter skin as a result of lower amounts of melanin in their skin. Since sun exposure in the poles is very limited, humans needed to receive as much as they could for the production of Vitamin D, and thus, their skins got lighter and less protected.

Which of the following is a type of tissue in plants that is dead at maturity?
victus00 [196]

Answer:

The correct answer will be option-B.

Explanation:

The plant tissues are composed of three types of cells: parenchyma, collenchyma and sclerenchyma.

The parenchyma and collenchyma remain alive at their maturity but sclerenchyma loses their protoplasm and become dead. These cells deposit lignin in their secondary walls and form hard tissues of the plant-like hard shell of a coconut. Sclerenchyma provides mechanical strength to the plant.

Thus, Option-B is the correct answer.
