Answer:

Geographical Isolation

Explanation:

Geographic isolation consists of separating a population by a geographical barrier, thus forming subpopulations. The geographical barrier can be a river, a mountain or a volcanic eruption, as shown in the question above.

As a result of geographic isolation, subpopulations begin to suffer different pressures and consequently the genes selected in one subpopulation will be different from the other subpopulation. Due to the geographical barrier, the two subpopulations will be prevented from crossing and the differences between them will become increasingly pronounced. Thus arose the subspecies.

Answer:

Geographical Isolation

Explanation:

Lava serves as geographical barrier to separate the two populations of monkey. These two isolated populations accumulate variations and gradually become reproductively isolated. Reproductive isolation brought about by geographical isolation leads to formation allopatric species which are now present in different geographical regions.

What does measles cause by

omeli [17]

Answer:Measles is a highly contagious virus that lives in the nose and throat mucus of an infected person. It can spread to others through coughing and sneezing. If other people breathe the contaminated air or touch the infected surface, then touch their eyes, noses, or mouths, they can become infected.Measles is caused by a virus in the paramyxovirus family and it is normally passed through direct contact and through the air. The virus infects the respiratory tract, then spreads throughout the body. Measles is a human disease and is not known to occur in animals.

It usually begins as flat red spots that appear on the face at the hairline and spread downward to the neck, trunk, arms, legs, and feet. Small raised bumps may also appear on top of the flat red spots. The spots may become joined together as they spread from the head to the rest of the body.
