Answer:

Mutation

Explanation:

Mutations can be defined as changes in genetic material, which are the main source of existing genetic variation. For ensuring genetic variability, that is, ensuring that individuals have different DNA, mutations are considered an important point in the evolution of living beings.

It is through mutations that important adaptive characteristics emerge, in addition to essential characteristics remaining in species that are different but that have similarities.

These processes also guarantees the selection of species most adapted species.  Mutations can be beneficial, neutral or harmful (genetic diseases or genetic "failures") and, therefore, are not targeted, occurring at <u>random</u>.

One type of active transport is called cotransport. In cotransport, the energy available from an ion moving through a transport
kompoz [17]

Answer:

b- It is a spontaneous process.

Explanation:

Passive transport is the type of transport of substances across the plasma membrane that occurs without energy expenditure and occurs spontaneously. There is no energy expenditure during passive transport because substances naturally move from the more concentrated to the less concentrated medium, ie in favor of the concentration gradient.

Substance transport occurs until concentrations inside and outside the cell are equalized.

According to this conceptualization we can conclude that the correct answer to your question is the letter B.
