Answer:
a. amount of a pesticide that can be applied to a food and how much of the pesticide that is permitted to remain on the food in the marketplace.
Explanation:
Pesticides are chemical substances used to get rid of or kill pests that attack crops on farmlands. These pesticides, although help the farmer to get rid of his pest problem and likely have an increase in yield, are dangerous to human and animal health if consumed.
As set up by the Environmental Protection Agency (EPA), pesticide tolerance is the amount or quantity of pesticide chemical that can be applied to a food and how much of the pesticide that is permitted to remain on the food in the marketplace.
The S interphase is when the DNA splits into two copies of itself
Answer:
The statement suggests ability of existing DNA molecule to replicate itself by the process of DNA replication. Each strand of double helical DNA can serve as template for the synthesis of new complementary DNA strand.
Explanation:
Watson and Crick proposed the double-helical structure of DNA. Accordingly, the DNA molecule is a double helical structure in which two polynucleotide chains are held together by base pairing between the complementary bases of two chains.
There are four nitrogenous bases present in DNA: adenine and guanine (purines) and cytosine and thymine (pyrimidines). Adenine always pairs with thymine and cytosine pairs with guanine base.
According to Watson and Crick, the ability of one DNA strand to base-pair with a complementary DNA strand suggests the existence of the DNA replication process. During DNA replication, each DNA strand should serve as a template to specify the nucleotide sequence of the new DNA strand.
