The brain and spinal cord begin as an embryonic structure called the neural plate. True or False
Simora [160]

Answer:

True

Explanation:

Ans;true

The neural plate is one of the features exclusive to the embryonic development of chordates. It is located dorsally to the notochord. The neural plate is the rudimentary nervous system of the embryo. During early development ,the neural plate is formed from the ectodermal layer . It undergoes changes in the position and arrangement of it's cells to form the brain and the spinal cord which comprises the central nervous system. It forms tissues and eventually organs by the deepening of the groove which forms ridges which eventually folds and fuses to form the neural tube . The tube differentiates into the prosencephalon, the mesencephalon and the rhombencephalon, from which the organs are formed

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.
