Answer:
The correct ansqwer is- Vitamin D
Explanation:
Vitamin D is the vitamin that can be synthesized by the human body itself therefore it is not an essential vitamin for human beings. Human skin is the part that helps in making this vitamin in humans.
The natural form of vitamin D is vitamin D3 which is formed by the sunlight exposure on the skin. When we expose our skin in the sunlight the UV radiation penetrated our skin and converts provitamin D3 into pre-vitamin D3 then this previtamin can be isomerized into the natural form of vitamin D Which is vitamin D3. So the right answer is vitamin D.
Answer:
Explanation:
the purple allele (C) is dominant to the pink allele (c).
The frequency of C represents p while that of c represent q. Using the formula p+q= 1
The proportion of pink flower is 153/1000 = 0.153. This is also the frequency of the genotype cc (q^2).
Thud to find q which is the frequency of the c allele,
q = √0.153
q = 0.3912
From the formula p +q = 1 we can find p p = 1 - 0.3912
p which is the frequency of the C allele
p = 0.6088.
B. the proportion of all purple flowering plants that are heterozygotes and homozygotes is 847 / 1000 = 0.847
A) .was immediately accepted
Explanation:
The theory of plate tectonics was immediately recognized as the explanation for the moving continents. It provided a more scientific background as why continents drift apart and the seafloor keeps spreading.
- The theory explains that the earth is broken up into series of slabs called lithosphere which moves on the weak, ductile and fluid asthenosphere.
- The movement of part of the earth mantle provided the mechanism through which the lithosphere moves. This is now known as the mantle convection.
- This theory provided a scientific mechanism through which the plate moves and seafloor spreads.
- It was immediately accepted when the theory was propounded by Alfred Holmes in the 1930s

Answer: D
Explanation: Wind turbines generate energy by moving. (Kinetic energy is movement.) Wind turbines, in more detail, are pushed by the wind which causes a transfer of kinetic energy which is then converted by the turbine into electrical energy.
