3. A population of 820 insects lives in a 1.2-acre area. They gather nectar from a
katen-ka-za [31]

Answer:

The plants have the higher population density. This is because, when compared with that of the insects, the number of plant species per acre area is higher; 2800 compared to 683.3

Explanation:

The number of individual species per unit area of land is known as the population density. Population density describes how crowded or spaced out a given species is in a particular area. The higher the population density, the more crowded the species are and vice versa. The formula for calculating population density is given as:

Population density = Number of species/land area

Population density of the insects = 820/1.2 = 683.3 insects/acre

Population density of the plants = 560/0.2 = 2800 plants/acre

Therefore, the plants have the higher population density.

This is because, when compared with that of the insects, the number of plant species per acre area is higher.

Many scientists believe horizontal gene transfer (HGT) is a significant source of genetic variation. Why
lawyer [7]

In prokaryotes, horizontal gene transfer (HGT), the transfer of genetic material from one organism to another organism within the same generation, is an important way to promote genetic diversity. HGT allows even distantly related species to share genes, influencing their phenotypes.

Transformation: Mode of genetic transfer in which “bare DNA” is taken up from the environment is taken up by cells

Transduction: Mode of genetic transfer in which genes are transferred by a bacteriophage to a bacterial cell

Conjugation: Mode of genetic transfer in which two cells must come in contact and genetic material is transferred to a recipient cell from a donor cell through its pili
