Answer:

Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool. Genetic drift can also cause a new population to be genetically distinct from its original population, which has led to the hypothesis that genetic drift plays a role in the evolution of new species.

How can a gene determine whether a person has albinism (give a molecular explanation.)?

Finger [1]

The TYR gene is responsible for the production of the enzyme tyrosinase which is crucial in the production of melanin which is primarily responsible for skin pigmentation and for pigmentation of other organs. In albinism, there is mutation of the TYR gene therefore there will be no transcription of DNA to mRNA and no translation of mRNA to the enzyme tyrosinase leading to its deficiency. The deficiency of tyrosinase will eventually lead to the absence of melanin and ultimately, the absence of pigmentation in an organism.

What is the name of an enzyme that catalyzes a reaction that removes a phosphate group from a molecule?

nlexa [21]

Answer:

Similar to the reaction that occurs in step 1 of glycolysis, a second molecule of ATP provides the phosphate group that is added on to the F6P molecule. The enzyme that catalyzes this reaction is phosphofructokinase (PFK).

Hope this helped!

Based on your ph testing results, can you categorize either of the microbes as acidophiles, neutrophiles, or alkaliphiles? expla

denis-greek [22]

Bacteria are classified according to the pH range in which they can grow. Neutrophile pH range: 5.5 - 8. Acidophile pH range: 0 - 5.5. Alkaliphiles pH range: 7.5 - 11.

Note: Since I did not find the table 2, I will explain what the classification of bacteria is, and propose examples for you to understand. Then, you will have to make your classification according to the table.

<h3>What is bacteria classification concerning pH?</h3>

Bacteria are cells that have different environmental requirements. Concerning pH, most bacteria have an acidic range in which they can grow keeping constant their internal pH level.

According to their pH requirement, bacteria can be classified as,

Neutrophiles

These cells can grow in environments in which pH is around the neutral pH level ⇒ 5.5 - 8

Acidophiles

These are bacteria that grow in acid environments with pH inferior to the neutral pH level ⇒ 0 - 5.5

Alkaliphiles

These bacteria grow in basic environments with pH superior to the neutral pH level ⇒ 7.5 - 11

Examples,

Bacteria pH range Classification

Escherichia coli 6-8 neutrophiles

Salmonella spp 5-8 neutrophiles

Lactobacillus acidophilus 4-6.5 acidophiles

Vibrio cholerae 8-11 alkaliphiles
