The correct option is (D) Nucleotide variability and average heterozygosity
The higher the proportion of loci that are "fixed" in a population, the lower are that population's nucleotide variability and average heterozygosity.
<h3>
What does it indicate when a gene in a population is fixed?</h3>
- In population genetics, fixation is the transformation of a gene pool from one in which at least two alleles of a certain gene exist in a given population to one in which only one allele persists.
- Any allele must eventually be lost entirely from the population or fixed (permanently established at 100% frequency in the population) in the absence of mutation or the heterozygote advantage.
- Selection coefficients and random variations in allelic proportions determine whether a gene will ultimately be lost or fixed. Fixation may relate to a specific nucleotide location in the DNA chain or a gene in general (locus).

Answer:
She was able to represent something small in a larger way.
Explanation:
Obviously if the bacteria need to be viewed with a microscope, they are extremely small. Darla likely does not have access to a microscope at her house, so using the macaroni and string, she made her own way of "seeing" the bacteria, but in a larger way. B is false because bacteria are small, not large. C is false macaroni do not need to be viewed with a microscope; in fact, this will probably allow you to not see them very well at all. D is false because macaroni wouldn't really show any patterns.

DNA is stored cold with the instagene matrix after boiling samples in order to
slow bacterial growth. In that way, you will greatly slow down the activity of
any remaining enzymes that could harm your DNA. Most likely it is a way of
preserving the DNA and to avoid it bacterial contamination.</span>
<u>Answer:</u>
Dr. Garcia’s emphasis best illustrates Biopsychosocial approach.
<u>Explanation:</u>
- It is an interdisciplinary model that looks at the interconnection between biology, psychology, and socio-environmental factors and their effects on individuals.
- It was developed by George L. Engel in 1977 and it was first of its kind that employed such diverse thinking.
- This model displays the development of illness through the complex interaction of biological, psychological, and social factors.
- This approach reopened new pathways for the idea of mind-body dualism which forgotten during the biomedical approach.
