Answers

Answer 1

Answer:

I think B is right answer

Answer 2

When considering the semi-conservative model of DNA replication,2 of the resulting DNA molecules would have a piece of the original DNA molecule after two replication events. Thus option B is correct.

what is semiconservative nature of DNA  ?

The semiconservative nature of DNA means where the nitrogenous bases of the “parent” strand act as a template for the synthesis of new DNA strands in the cell.

The DNA has two helices where one strand is parent DNA strand of the DNA  helix while the other strand of DNA is the newly synthesized one where all the genetic information is copied from the template strand.

During DNA replication the DNA molecule is broken and separated into two single DNA strands, each of the strand is  duplicated to create two new double helix strands, which preserve one strand from the parent sample in each replication.

Therefore, due to the duplication the strand of DNA have one of the original parent strands, by the process is semiconservative DNA replication.

A farmer is spraying his crops with a specific pesticide. He notices a drastic decrease in the insect population, so he uses the same pesticide the next year. This time, more insects survive. The next year, almost no insects are killed by the pesticide. Why is this happening?

Answers

Answer:

Probably insects developed resistance to the pesticide.

Explanation:

The term resistance refers to an inheritable change in the population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used in order to reach a certain effect on the insect population.  

Insecticides might produce a genetic modification in the insects, leading them to survive under the effects of the chemical. Insects evolve with the capability of tolerating the poison dose that normally is used to destroy a normal population of plagues.

In the exposed example, the first time that the farmer sprayed the pesticide, the insect population decrease sharply. This means that the chemical affected them severely. The surviving individuals probably suffered a genetic modification and survived. They probably passed this modification to the following generations, which expressed it, and developed resistance to the pesticide.
