Answer:

The bacteria with the mutation will survive.

Explanation:

In this population, if there is a group of bacteria of the same specie that mutate and this mutation is the expression of antibiotic resistance, this mean that the "mutant bacteria" are going to live spite the action of the drug.

Meanwhile the rest of the population is going to die because these group of living things are susceptible to the antibiotic, that means, they are going to die.

In the other hand, the "mutant" living things, by passing the time are going to reproduce and lead a new generation of bacteria resistant to the antibiotic.

Answer:

If the calcium levels in blood increases, then there is increase in blood glucose level.

Explanation:

Calcium in blood plays a vital role of homeostasis in regards to level of secretion of insulin. If the calcium level is altered, the homeostasis mechanism is hampered. Several  researches have shown that alteration of serum calcium level affects the metabolism process of carbohydrate and makes the person vulnerable to risks of diabetes mellitus and associated complications. Hence during calcium supplementation, the person's blood glucose level must be considered.

bekas [8.4K]

Answer:

We could feed them with another type of food free of silver salts.

Explanation:

When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.

If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.

Describe the relationship between proteins and nucleic acid
Dmitry [639]

Answer:

Explanation:

Proteins and Nucleic Acids are not similar in structure. They look nothing alike, either as large molecules or in terms of their building blocks. While they're both made up of mostly carbon, hydrogen, nitrogen, and oxygen, the elements are assembled in vastly different ways. The major relationship between the two has to do with protein production -- DNA contains the information that a cell uses, with the help of RNA, to make protein.
