Using data, provide evidence that evolution is an ongoing process.
Vlada [557]

The major evidence that the evolution is still ongoing is mutations that occur. Those changes at gene level happen by chance during the process of copying DNA and change through the populations over time. Individuals who reproduced can pass that mutation to their offspring. When carriers with a specific mutation are better able to survive and reproduce, natural selection will favor them. That is the way of new variant to be passed down and spread through the population.

Albinism is a condition in which pigmentation is lacking. In humans, the result is white hair, non-pigmented skin, and pink eyes
stealth61 [152]

Answer:

1/4 or 25% chance/ probability of having an albino child.

Explanation:

Albinism is a recessive trait, this means that a person need 2 copies of the allele to express this condition. If both parents are normal their genome must be Aa ("A"=normal condition and "a" recessive allele) when they produce gamets they could either be "A" or "a" but when fertilization happens there's a 25% chance of 2 gametes with the recessive trait to meet, hence producing an albino.

It is important to understand that this is only probability. A couple could have 6 children and all of them could be normal.

bezimeni [28]

Answer: Divergent, or destructive plate margins cause volcanoes. As the more dense plate subducts, it will melt at depth and the water driven off, will lower the melting point of the overlying mantle wedge, this will create a type of magma. Volcanic Island Arcs are formed at oceanic-oceanic destructive plate margins.
