The table below identifies three classes of genes that affect the cell cycle.

1 answer:

6 0

The correct option is this: PROTO ONCOGENES BECOMES ONCOGENES.
Proto oncogenes genes are those genes that regulate the process of normal cell division in the living system. These cells starts cell division when necessary and terminate the cell division when the necessary cells have been formed. When these genes lose the power to regulate cell division, the cells continue to divide indefinitely without stopping and this leads to a medical condition called cancer. At this stage, the proto oncogenes have been turned into oncogenes, which are genes that caused uncontrolled cell cycle divisions.

A scientist constructs a graph to show the age structure that f the human population of county

DedPeter [7]

Based on the graph, it can be concluded that the population is increasing rapidly because of the youth of the population.

<h3>What is population?</h3>

The population of a species is the number of organisms of the same species found within a given habitat.

Population graphs are used to describe the trend in the population of a given species of organisms.

The factors that affects population growth of a country include:

fertility rates,
mortality rates or life expectancy,
the initial age profile of the population, and
migration

Given the population graph of the country, the conclusion can be drawn is that the population is increasing rapidly because of the youth of the population.

In conclusion, the higher the fertility rate the faster the population growth.

Sindrei [870]

Answer & Explanation:

Aquatic plants don't have to deal with drying stress, so, for example, the number of stomas will be lower or even absent. Also, the pressure and temperature conditions underwater are way different than on earth. Therefore, the movement of fluids and metabolic products will be quite different.
