Homoygotes for one allele are favored over all others.
Answer 1Two broad processes that make evolution possible are 1 : directional forces including mutation , migration and selection and 2: nondirectional forces that include random genetic drift , bottleneck effect , founders effect ,and chance variations .Answer 2Evolution is most commonly described as a combination of reproductive variation and differential reproductive success.Reproductive variation in itself is a "non-directional" phenomenon, that produces mostly random variations. Differential reproductive success (or: natural selection) is a "directional" phenomenon, that basically acts as a mechanism limiting the set of "directions" produced by random variation.
Go extinct.
If your PC freezes or behaves badly, the likely cause of this is the RAM.
Answer is (A) Carbohydrates.
We can not answer this without "which" and "the other three".
The most likely cause of directional selection is a shift in environmental conditions that favors individuals with a particular extreme trait over others. This can lead to the gradual increase in frequency of that trait in a population over time.
Homoygotes for one allele are favored over all others.
Aside from decreasing genetic variation they both are not normal Gaussian curves. Disruptive selection has two normal curves at either end of the distribution. Directed selection has an abnormal curve with most of the data distributed is a skewed manner from the mean of distribution.

Aspirin is the NSAID that is most likely to cause ulcers.
A convenience survey or a self-selection survey is most likely to be affected by bias
Some are directional like the eagle F1, however most are not directional.
When the largest organisms are most fit, it shows a pattern of directional selection, where individuals at one extreme of a trait distribution have higher fitness. This can lead to a shift in the trait distribution over time, favoring the larger size.
Carelessness and inattention is most likely the cause of someone to fall overboard.
The eccentric muscle contraction is most likely to cause discomfort in q5.
