Question

The image below represents which factor that can lead to evolution at the population level?
A- mutation
B- natural selection
C- genetic drift
D- gene flow

Answer 1

what do u think?

Answer 2

either a or d

Answer 3

can u define each that u chose?

Answer 4

u might be able to get it once u define them

Answer 5

In population genetics, gene flow (also known as gene migration) is the transfer of alleles or genes from one population to another. Migration into or out of a population may be responsible for a marked change in allele frequencies (the proportion of members carrying a particular variant of a gene).

Natural selection is the gradual process by which heritable biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. It is a key mechanism of evolution.

Answer 6

It depends on how you would interpret the images in terms of population.

If you looked and compared two populations and the colours are the variations within that population, the conclusion is that one has more variations than the other. The only possible explanation for this is the presence of mutation. The presence of variation however does not change the population as a whole. Evolution is at a population level.

Another possible interpretation is that the images's varying colours represent populations. If that were the case, then one has more variations or kinds of population than the other. One of the possible explanation to this is that new species arose and reproduced and formed their own population. It may be a case of speciation.

Pie charts usually are used to represent an entire population, so the first interpretation would likely fit the scenario.

Answer 7

sorry somy..:(
i already typed and then ur msg popped up..:(

Answer 8

lol its okay
os's lagging <.<

Answer 9

So A like i said?

Answer 10

You can only select one answer and provide an explanatio as to why that is. It is not a guess work, but rather a formulation of hypothesis, which hinges upon the principle of falsifiability.

Answer 11

I am in a tunnel right now, so my connection might be choppy.

Answer 12

what?

Answer 13

You said A or D, but provided no justification for either of the two. In science, we always try to provide an explanation to justify our answers.
