A change in a sequence of DNA bases in a bacterial cell has resulted in a mutation. This mutation has increased the ability of t
Svetllana [295]

Answer:

The relative frequency of the mutation will increase as time passes.

Explanation:

This random mutation has, by chance, caused a phenotype that is beneficial to the bacteria. This mutation improves the fitness of the bacteria, as they are able to utilize more food sources. This reduces the chance of starvation and death of the cell. Therefore, cells with this mutation are more likely to survive, and for longer.

In times where nutrients are scarce, bacteria without the population will die off. But the bacteria with this mutation will be more likely to survive and pass on their genetic material. Therefore, over time, the frequency of this mutation will increase.

Which type of mutation occurs in respective cells and can be passed to offspring
RoseWind [281]

Germline mutation is the types of the mutation of the respective cell can be passed to the offspring.

<u>Explanation:</u>

During the sexual reproduction somatic mutations occur in the nonreproductive cells, they are passed to the daughter cells during the mitosis but not to be the offsprings.

During the sexual reproduction, a mutation is used in large scale evolution that can be passed to the offsprings.

Its occurs in the cells such as egg and the sperm are called as the germ line mutations. A single sperms line mutation have a light effect in the gene but there is no change in the phenotype.

What are the common features of the major lipids-- fatty acids, triacylglycerols, phosphoglycerols, sphingolipids, polyisoprenoi
algol13

Answer:

The common characteristics between fatty acids, triacylglycerols, phosphoglycerols, sphingolipids, polyisoprenoides and sterols are that they are nonpolar substances. Thus, these substances are soluble in nonpolar solvents, unlike water.

Explanation:

Lipids are the most diverse range of biomolecules that have a hydrocarbon chain as the backbone. The hydrocarbon chain is formed of series of carbon atoms and balanced by hydrogen atoms. Due to their close electronegativity, the hydrocarbon chain renders the lipid its nonpolar property. Water is a polar solvent, and thus the lipid molecules are not soluble in it. The metabolism of lipids causes oxidation of fatty acids, that in turn generate energy.
