Question

Many gardeners use a chemical weed-killer to control plant pests in their gardens. However, many weeds have begun to develop a resistance to these chemical poisons.

The resistance that the weeds have developed may be passed down to future generations through _________ .
A.apoptosis
B. genes
C.mitosis
D.revolution

Answer 1

The answer is B) genes

Step-by-step explanation:

Genes are any trait passed down from parent to offspring.

Answer 2

Ans. (B). Genes.

The chemicals that kill the weeds are known as herbicides. Herbicide-resistance is defined as the inherited ability of weeds to survive an application of herbicide, that can kill a normal weed plant of same species.

The resistance develops due to mutations in genes that were sensitive to those chemicals in wild-type forms. As genes are responsible for transfer of characteristics from one to another generation, the herbicide-resistance is also passed down to generations through genes.

Thus, the correct answer is option (B).
