Which of the following is not a negative impact of pesticide use?a. toxic to insects
b. promotion of pesticide resistance in insects
c. harmful to wildlife
d. pollution

Answers

Answer:

a. toxic to insects is the correct answer.

Explanation:

  • Toxic to insects is not a negative impact of pesticide use.
  • The pesticide is used as a toxin against the insects,
  • It is used to control the insect's infestation and to kill the insects.which is not negative because we need to eliminate insects to control insect infection, diseases and to protect the crops from the insect.
  • The other three options have negative effects caused due to the use of pesticides.

What is the correct order for the following events in excision repair of DNA? (1) DNA polymerase I adds correct bases by 5¢ to 3¢ replication. (2) Damaged bases are recognized. (3) DNA ligase seals the new strand to existing DNA. (4) Part of a single strand is excised.

Answers

Answer:

2, 4 , 1 and 3

Explanation:

The correct order for events in excision repair of DNA are:-

2, 4 , 1 and 3 that is the

1st step would be:

(2) Damaged bases are recognized.

2nd step of the process

(4) Part of a single strand is excised.

3rd step will be

(1) DNA polymerase I adds correct bases by 5¢ to 3¢ replication.

and the final step in  excision repair of DNA is

Scientific investigations often lead to the formulation of new scientific questions. The observations Charles Darwin made during his time aboard the H.M.S. Beagle prompted him to ask which question? Do living organisms change over time and, if so, how? Are the finches of the Galapagos Islands the same as those on the mainland? Can selective breeding occur in nature? Can the accumulation of gradual changes in a population lead to a new species over time?

Answers

Charles Darwin is known as the man behind the concept of natural selection - that some traits that give relative advantage would appear more and more often, eventually changing the species over time. The correct answer is thus the last one: "the accumulation of gradual changes in a population leads to a new species over time". It especially can't be the first option - we know that organisms chance over time (children become adults) - so we didn't need Darwin to realize that, this is somehting that people have understood for a long time. His discovery was connected to selective breeding, but his major insight was gradual evolution, not the breeding itself.

Charles Darwin observed that the accumulation of gradual changes in a population leads to a new species over time.

Further Explanation:

Scientific experimentations are the logical and practical procedures that determine the efficiency of a particular claim using scientific means. Charles Darwin was the one who gives the theory of evolution that occurred by natural selection. According to Darwin, evolution was descent with modification. There is a common ancestor between the species that changed over time and became new species. Natural selection is the reason why the population grows adapted for well suited to the environment over time.  

 

The pre-existing heritable variation in the group is the prime condition for natural selection to happen in the environment between the species. Natural selection is the process by which the well-suited organism in the population gets selected due to stress in the atmosphere thus evolving the species. In Darwin's book ‘The Origin of Species’, all these facts and information are mentioned, and the ideas of evolution and natural selection are well-reflected.

What happens to time as you travel close to the speed of light?

Answers

Time slows down. Einstein's Twin Theory states that if there were two identical twins, and one traveled in space at the speed of light while the other stayed on Earth for about 50 years, the twin in space would not have aged much, and the Earth twin would be an old man,
