Answer:

D. A population with high genetic biodiversity is better able to respond to environmental stressors.

Explanation:

The genetic biodiversity of a species is the diversity of alleles that it possesses in its genetic pool. For a given gene, a population can have one or more alleles; and the more alleles the population has, it will be more diverse. Under normal conditions (without stress), the alleles that are present in high frequency in a population,  are those that best respond to the environment where the population occurs. However, if some environmental condition changes and some type of environmental stress emerge (ie drought), it is possible that these alleles no longer respond equally effectively and then, it is possible that the  alleles that on normal conditions occur with low frequency, are more adequate to face the stress. A population with fewer alleles (less genetic diversity) has terefore fewer options to deal with environmental stressors and<u> a population with high genetic biodiversity</u> will do this better.

Answer:

<u>C) proteins with gain-of-function mutations</u>

Explanation:

<u>Gain-of-function mutations: </u>In biology, the term "gain-of-function mutation" is described as one of the different types of mutation in which the altered or changed "gene product" consists of an entirely new pattern or molecular function associated with gene expression. However, the "gene-of-function mutations" are being always considered as "Semidominant or Dominant".

<u>In the question above, the correct answer is option C.</u>

What is the name of the darker blue/purple section that is cut out of the magenta molecule?
seraphim [82]

Answer:

Basophils

Explanation:

Basophils are a special type of  white blood cells that are produced in the bone marrow and their main role entails inducing and maintaining allergic conditions.

In staining, Basophils shows  dark blue granules which contains histamine, heparin and peroxidase. In preparation of Schiff reagent ; magenta molecule ( Fuchsin dye ); gives a range of colors from magenta to purple. The stain cause nuclei to become blue, and glycogen and fungi to become magenta in color.

What alternate form of genes do nucleic acids have that allows them to offer variability allele codon nucleotide chromosome
Y_Kistochka [10]

Answer:

The options to this question are:

A) allele

B) codon

C) nucleotide

D) chromosome

The answer is A) allele

Explanation:

RNA and DNA are the two nucleic acids in living organisms used for transferring and storing genetic information. Deoxyribonucleic acid (DNA) is the genetic material in living organisms that contains segment coding for useful products/proteins and transmits genetic information from one generation to another. These segments are called GENES.

However, genes contain an alternate form responsible for genetic variation in the traits coded for by them. These alternate or variant form of a gene is called ALLELE. In a diploid organism like human, each trait is encoded by genes which contain contrasting pair of alleles that allows variation for that particular trait i.e. two alleles for each gene. For example, height trait in humans are encoded by gene, which possess two alleles; one coding for short variety (t) and the other for tall variety (T).
