Answer:

RNA

Explanation:

Transcription is the second stage of central dogma of life (1. replication, 2. transcription, 3. translation).

During transcription, DNA (which is already replicated) is transcribed to RNA. This is because, the genetic information is present within nucleus and thus it is required to be transported outside the nucleus in order to perform key enzymatic functions. Therefore, transcription takes place and the genetic information travels outside in the form of RNA, where ribosomes decode this message to form proteins. The ribosomes make proteins (translation) required for enzymatic functions.

Answer:

RNA

Explanation:

Transcription is the synthesis of RNA.

Transcription is a biological process through which a gene sequence is copied from DNA to messenger RNA which is responsible for carrying necessary information for the production of protein.

The RNA polymerase then uses the given information and duplicates it to form a new complementary RNA molecule.

Therefore the synthesis of RNA is known as transcription.

I hope the answer is helpful.

SashulF [63]

Answer:

Explanation:

Green crabs have chemoreceptors located on an antenna.

These are long segmented appendages near the crab´s eyes that have both chemoreceptors and allow them to feel the surroundings.

Crabs also have antennules, like short appendages close to the antennas that allow them to sense their environment. A crab can "taste" using hairs on their mouthparts, pincers and even its feet.

So they can detect the salinity of the water by "taste" using the antennules. If these antennules are bathed with nonsalty water, the information the crab´s brain receives is to increase the salinity of its body by the system explained above, increasing its rate of urine production.

I hope it helps!

Osmosis and tonicity

Sergio039 [100]

The blood cells likely placed in a "hypotonic solution".

Option: A

Explanation:

When human blood cells are immersed in a solution with a low concentration of solute than is present in cells, osmosis allows water to pass through the cells, allowing the cells to get swollen; such a fluid is hypotonic to the cells. But when held in a solution with a greater concentration of solute, osmosis allows water to pass out of the cell, the cell is smaller and crenated in form; then a solution is hypertonic to the cells.

Healthcare facilities preserve human blood cells in a plasma solution that has the proper salt and protein ratios. Such solution is formulated to be mildly hypertonic to the red cells, thus maintaining the integrity of the cells and avoiding hemolysis.

18.Substrate-level phosphorylation

77julia77 [94]

Answer:

(B) Energy released from the chemical reaction is used to directly phosphorylate ADP.

(D) Energy released from the chemical reaction is used to directly reduce NAD+

Explanation:

phosphorylation is a addition of phosphoryl group to an organic compound.Substrate level phosphorylation is a process where there is ATP is produced from ADP by transferring a high energy phosphate group from phosphorylated metabolic compound.This process occurs in glycolysis and citric acid cycle.and this pathway is exergonic pathway
