The correct answer is option c- nearly all mammals descended from common ancestors.

Human cervical vertebra consists of 7 bones from top to bottom:

- C1

- C2

- C3

- C4

- C5

- C6

- C7

Cervical vertebra are located just below the skull are the neck bones that control the neck movements. In humans, cervical vertebrae are the smallest of all vertebrae. In different organisms, the size of these vertebrae vary.

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.

nataly862011 [7]

Answer:

The tissue fluid is less concentrated

Explanation:

Water naturally moves via the passive process of OSMOSIS, which is the movement of water from a region that is less concentrated to a region that is highly concentrated via a semipermeable membrane.

In this question, there is said to be a net movement of water into a cell from the surrounding tissue fluid. Based on osmotic principles, this means that the solute concentration of the tissue fluid is lower than that of the cell. Hence, the tissue fluid contains more water, causing it to move towards the cell.
