I believe that the answer is A, if I am not mistaken!
Answer:
A. The ash would increase the albedo and decrease the global temperature
Explanation:
The volcanoes can have a big impact on the global temperature. If the volcanic eruption is big enough, and the volcanoes manages to propel very large amount of ash in the atmosphere, the whole planet will feel the effect. The ash will make a layer in the atmosphere around the planet. This layer will increase the albedo of the atmosphere, as the ash will block big portion of the sunlight. That will result in much less sunlight reaching the surface of the Earth, thus in sharp decrease in the global temperatures.
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.
Gametes are reproductive cells that unite during sexual reproduction to form a new cell called a zygote. Sexual reproduction needs zygotes to reproduce that is why gametes are needed. Asexual reproduction doesn’t need gametes because there is only one parent and there is no fusion of gametes.
