Scientists recently published a paper about an endangered population of Scarlet Bass (species A) in Lake Erie. The authors also

published its entire mitochondrial DNA sequence on Genbank, an online system where scientists submit genomic data. Another group of scientists later published an article using molecular data to estimate gene flow among populations of the very abundant Grey Bass species (species B) in Lake Erie, and published mitochondrial data on Genbank as well. After you read the papers you realize that the ranges for species A and a few isolated populations of species B overlap; you look at the sequence data published online from both studies, and you realize they are very similar and differ only by a few nucleotide differences. 8. Do you think these are closely related species, or variants of the same species

Answer:

They are variants

Explanation:  

The biological concept of species states that members of the same species can reproduce they have a genetic reservoir in common: many genetic variants.

Genetic variability is the measure of a species organism´s tendency to differentiate. In genetic variability, individuals of the same species are not identical. They are recognizable as members of the same species, but they differ in shape, function, and behavior. There exist variations among individuals of the same species.

Genetic variability originates from mutations, recombinations, and karyotype alterations. It allows or makes possible evolution.

Groups A and B can be considered variations of the same species. They not only overlap but also share most of the genetic sequences with only a few nucleotide differences.

These variations might be the previous step for sympatric speciation.

Answer:

D) The porcupine is showing a physical characteristic adaptation and the opossum is showing a behavioral adaptation.

Explanation:

Adaptation, which refers to the ability of an organism to adjust to changes in their external environment in order to survive, is of different types namely: physical/structural, behavioral etc.

- A physical or structural adaptation is a possessed physical characteristics/traits of an organism that enables it adapt.

- A behavioral adaptation is an organisms change in behavioral pattern or responses made to changes in the environment.

According to this question;

- A porcupine is said to have quills on its back which helps protect it from predators. This shows an example of STRUCTURAL or PHYSICAL ADAPTATION, which is the QUILLS it possesses.

- An opossum is said to pretend to be dead and become stiff when threatened. This is an example of BEHAVIORAL ADAPTATION because the opossum responds behaviorally to being threatened.

Serga [27]

Answer:

pls mark brainlest The chemical composition of an igneous rock tells us about the origin of the magma, beginning with which type of rock melted within the earth to form the magma in the first place, and how deep in the earth the melting occurred. Once magma has formed inside the earth, its composition may be modified.
