Answers

The right answer for the question that is being asked and shown above is that: "d. uneven so that the tendons and ligaments in the ankles and knees are strengthened." The best surface to run on is one that's d. uneven so that the tendons and ligaments in the ankles and knees are strengthened.

Doctors do not administer vaccinations to people who are too sick. Which best explains why? A. The weakened or dead form of the pathogen may not have any effect on sick people. B. The weakened or dead form of the pathogen may have a fatal effect when it is combined with medication that the sick people are taking. C. The digestive systems of sick people may be negatively affected by the weakened or dead pathogen. D. The white blood cells of sick people may not be able to efficiently handle the weakened or dead form of the pathogen.

Answers

The Correct answer is option D

When a person is sick then it means that its immune system is already weak and the white blood cells of sick people do not work efficiently.

In this case if the body is administered with vaccination then there are chances that the person might die or become adversely sick.

Vaccination is given to evoke immune response by the help of White blood cells and if it is already not working efficiently then the vaccine can make the make person more ill.

D. If you give someone a vaccine while they are sick the body might not be able to handle both "infections"

If a dna analysis reveals that a cell has 60 ng of adenine and 20 ng of cytosine, how much thymine and guanine are in the cell? defend your answer.

Answers

Answer:

Thymine= 60 ng

Guanine= 20 ng

The complementary base pairing occurs between adenine and thymine and guanine and cytosine bases.

Explanation:

According to the Chargaff rule, a double-helical DNA molecule has an equal number or equal amount of adenine and thymine bases since adenine always pairs with thymine. Similarly, the amount of guanine base is equal to that of the cytosine base.

Chargaff rule is based on the complementary base pairing between purine and pyrimidine bases. According to the given information, the amount of adenine is 60 ng. Therefore, the cell would have 60 ng thymine. Similarly, the amount of the cytosine base in the cell is 20 ng which means that the cell would have 20 ng of guanine base.

Final answer:

According to Chargaff's rules, the amount of adenine is equal to the amount of thymine, and the amount of cytosine is equal to the amount of guanine in a DNA molecule. Thus, the cell should have 60 ng of thymine and 20 ng of guanine.

Explanation:

The question refers to the base pairing rules in DNA, which were discovered by Erwin Chargaff and are now known as Chargaff's rules. According to these rules, the amount of adenine (A) in DNA is always equal to the amount of thymine (T), and the amount of cytosine (C) is always equal to the amount of guanine (G).

In this case, if the DNA analysis reveals that the cell has 60 ng of adenine, the cell should also contain 60 ng of thymine according to Chargaff's rules, since A = T. Similarly, if the cell contains 20 ng of cytosine, there should be 20 ng of guanine as well, because C = G.

So, based on the base pairing rules in DNA, the cell should have 60 ng of thymine and 20 ng of guanine.
