A different form or version of something (within a population or a species)

Based on the assumptions described in the introduction why might the mark and recapture method of population estimation be more

AleksAgata [21]

Answer:

In ecology, the mark and recapture method is utilized to predict the population size of the animals. In the method, the part of the population is caught, marked, and then discharged. Afterward another part is caught, and the number of marked organisms within the sample is measured.

The mark and recapture method of predicting the population is more precise in the setting of lakes as a lake is a fairly steady environment, while the streams and rivers are in motion, and thus the population is much more dynamic.

Answer:

Explanation:

Scenario 2: R is codominant with r.

Scenario 3: R and S are completely dominant to rand s, respectively; R and S are linked by 15 m.u. and do not interact with each other.

Scenario 4: Genes R and S perform the same function; R and S are completely dominant to r and s, respectively; and R and S are unlinked.

Scenario 5: R and S are completely dominant to r and s, respectively; R and S are linked by 10 m.u. and show dominant epistasis.

Question number 1.
The correct answer is: The insects are the same species.
There is still a lot of discussion in the scientific community on how should we define a biological species, but one of the main points that all scientists agree on is that the members of the same biological species are individuals that can successfully reproduce and leave viable and fertile offspring.

Question number two
The correct answer is : The graph showing directional natural selection.
In the case of the fish species of the coral reef, there are two extremes of the phenotype the dark orange and the pale one.
Before the bleaching of the coral, the dark orange phenotype was better adapted to the environment. But after the bleaching of the coral, the pale phenotype now resembles the coral background more and it is able to hide from the predators better than the dark orange one.
This will result in natural selection favoring the pale phenotype more and working in the direction of this extreme on the graph.
