Answer:
39 double helical DNA molecules.
Explanation:
- Meiosis always produces haploid cells.
- Sperm and Eggs are produced after meiosis.
- So, sperm and egg cells of dog would have 39 chromosomes and one double helix DNA molecule is present in each chromosome comprising 39 double helical DNA molecules.
<em>A chromosome has one DNA molecule before replication and have two DNA molecules after DNA replication.</em>

The correct answer is letter C.
Bryophytes have biflagellate gametes and cuticle. The cuticle serves as the covering of the soft tissue of the plant which provides protection and prevents damages on the walls of the plants. The biflagellate gametes develop also as a form of protection as well. These plants have an aquatic ancestry because of their dependence on water for reproduction and survival.

Answer: Metabolic alkalosis
Explanation: Metabolic alkalosis refers to a metabolic condition in which the tissue’s pH is increased above the normal range (7.35–7.45). This occurs as a result of decrease in the concentration of Hydrogen ion, which results to increased bicarbonate in the body system. It can also be caused by direct increase in the bicarbonate concentrations.
None of the above? I’m guessing, secondary, primary and tertiary doesn’t sound right !
