<h2>Answer:</h2>

No, this not the accurate statement.

<h2>Explanation:</h2>

As in article in the local paper, a new copper line is found in New Mexico. And all that is needed to identify a substance is the mass and the volume of the substance. But this is not the truth because to identify a substance we need to know about is an atomic number, atomic mass etc so that we can define it in periodic tables.

Of cells is one of the processes that help multicellular organisms maintain homeostasis
lord [1]

Answer:

<u><em>Reproduction</em></u> of cells is one of the processes that help multicellular organisms maintain homeostasis.

Explanation:

In biology, homeostasis can be described as the capability of an organism to maintain its constant internal environment despite the changes in the external environment.

External factors like pathogens in the environment tend to kill cells in our body like the skin cells and the immune cells. Through the process of cell division, our cells can reproduce and hence, maintain an equilibrium of the internal conditions.

Reproduction of cells also causes growth. Hence, the process of reproduction of cells maintains homeostasis.

After doing PCR on the same region between two individuals, you notice that each person's DNA yielded pieces of different sizes.
vitfil [10]

Answer:

C. This is an example of VNTRs.

Explanation:

VNTRs are Variable Number Tandem Repeats. These are short sequences of DNA repeated in tandem (that is, the sequences are repeated one next to the other) a certain number of times. Unrelated individuals have a different number of repetitions for a certain region of the DNA, therefore the total length of the fragment is variable among individuals, depending on how many times the short sequence is repeated.

Why do polygenic characteristics have many phenotypes?
chubhunter [2.5K]

Answer:

The involvement of more than two genes.

Explanation:

The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.

The skin color and height are polygenic characterstics in humans.
