Answer: wave energy

Explanation: the mining of copper and extraction of crude oil will sooner or later lead to their exhaustion and may take millions or thousands of years for them to replenish.

Coal is also non-renewable and it is a dirty source of energy. The reason why people reduced the consumption coal and sorted out new sources of energy is because they knew it will soon be exhausted.

The answer is wave energy and it is the main form of sea energy. We all know the sea won't run dry. The sea level might decrease or increase but never dry.

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?
Serggg [28]

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.
