I
believe the best answer choice for this question is D. there is no gene flow.
Answer:
C
Explanation:
When researching on the lineage of 2 animals from a common ancestor, one can deduce it accurately from DNA samples and various bodily characteristics from the body of the 2 animals in comparison to the common ancestor.
A) Strands of DNA allows for scientist to deduce the percentage similarity between 2 animals. The more similar means that the closer the relatedness is between 2 species.
B) Bones and muscle structure gives one a rough gauge on similarity of both organisms. E.g. Compare human bone, muscle to chimpanzee bone muscle.
C) Comparison of food items is the worst methods as different species may feed on different types of food due to natural selection. E.g. Finch bird example on the galapegos island or sth.
D) growth of embryos of similar animals would have similar developmental stages and changes that is quite distinct to each species, allowing one to deduce the closeness of the 2 animals to a common ancestor.
Hello!
The correct answer is C. We know this because it consists of an incredibly simple polypeptide chain that has a continuous pattern. The rest of the choices represent complex chains.
I hope I helped!
Answer:
Stabilizing selection is occurring because the average is favored.
Explanation:
There are different types of natural selection: sexual selection, stabilizing selection, directional selection, frequency-dependent selection, and disruptive selection.
Balancing selection, also called Stabilizing selection, eliminates individual with extreme traits and favors individual that exhibit medium-range characteristics, that gets to survive.
In the exposed example, babies with very low or very high birth weight have fewer possibilities to survive. Stabilizing selection eliminates individuals with extreme weight and favors individuals that exhibit medium weight, which are the ones that get to survive.
