aggregate to form cloudy patches in the visual of the person that is called
cataracts. The damage due to ultraviolet light and dehydration most likely
cataracts interfere the vision. This can be treated through surgery replacing
the lens with an artificial lens. LASIK/laser assisted in situ keratomileusis
is a computer generated guide laser to let the curve of the cornea reduces for
myopia so that the retina can moved back its focus. This does not corrected by
glasses, so this is the only way to correct this kind of problem. </span>
Answer:Characteristics
Explanation:
Most traits would come from characteristics and ancestry.
Answer:
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.

Causes of speciation
<span>Geographic isolation
In the fruit fly example, some fruit fly larvae were washed up on an island, and speciation started because populations were prevented from interbreeding by geographic isolation. Scientists think that geographic isolation is a common way for the process of speciation to begin: rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations.
</span>Reduction of gene flow
<span>However, speciation might also happen in a population with no specific extrinsic barrier to gene flow. Imagine a situation in which a population extends over a broad geographic range, and mating throughout the population is not random. Individuals in the far west would have zero chance of mating with individuals in the far eastern end of the range. So we have reduced gene flow, but not total isolation. This may or may not be sufficient to cause speciation. Speciation would probably also require different selective pressures at opposite ends of the range, which would alter gene frequencies in groups at different ends of the range so much that they would not be able to mate if they were reunited.</span>
