The correct answer is: 5) NER recognizes helix distortions, while BER recognizes specific base damage.
DNA damage that occurs as a result of radiation, oxidizing reagents, chemicals and other mutagens can be repaired. Excision repair repairs single strand DNA damage and it includes:
• Nucleotide excision repair (NER)-it detects and repairs types of damage that distort the DNA double helix such as those of UV radiation (thymine dimers); not only the damaged nucleotide(s) are removed but also a surrounding patch of DNA
• Base excision repair (BER)-it detects and removes certain types of damaged bases (small, non-helix-distorting bases); enzyme glycosylase is responsible for this type of repair
Answer:
Weight of the soil (500g)
Explanation:
According to this question, some students are conducting an experiment in order to find out which of the different soils used absorb heat the fastest. For the first test, they put 500 grams of SAND in a beaker and put a thermometer in the sand.
In an experiment, the variables that must be kept constant for all the groups is called the CONSTANT OR CONTROLLED VARIABLE. This is done in order not to influence the outcome of the experiment. In this case, the weight (500g) of the soil should be kept the same for all other tests.
This means that for the remaining soil being tested, 500g of each type of soil should be used.
To compare the average weight of mallards raised on corn to the average weight of mallards raised on rhubarb. Thus option D is correct.
<h3>What is hypothesis testing?</h3>
In statistics, hypothesis testing is a method for determining if survey or experiment results are relevant.
To compare the average weight of mallards raised on corn to the average weight of mallards raised on rhubarb. this experiment is to be done in order to best test this hypothesis.

Karyokinesis
The process by which the division of the nucleus takes place during the cell cycle is known as karyokinesis. It is usually followed by cytokinesis. It can take place by mitosis, meiosis, and amitosis. Mitosis is an equational division, meiosis is a reductional division while amitosis, is an indirect division of nucleus.
