Why saturated solution prepared at higher temperature gives crystal on cooling​

Biology
1 answer:
charle [14.2K]3 years ago
4 0

Answer:

Cristal is formed when the solution is cooling because the solvent can't keep all the molecules of the substance and these molecules are beginning to leave the solvent and form solid crystals.

Explanation:

It means that every crystal is formed of one molecule of the solvent. When the solvent reaches room temperature, it is moved to the ice bath to finish the process of crystallization.

If a cell has 15 pairs of chromosomes (n = 15), it has 30 chromosomes (2n = 30). At the

end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter

cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e.,

nadezda [96]

Answer:

The correct answer is - 14 OR 15 ATP.

Explanation:

At the end of the glycolysis, two molecules of the pyruvate produced in the cytoplasm which is followed by the pyruvate oxidation that takes place in the matrix of mitochondria in eukaryotes.

During the oxidation of the pyruvate, a carboxyl group is eliminated from the pyruvate and released as CO₂. Then the two carbon molecules oxidized produced in the first step and NAD+ accepts the electron and change into the NADH. The oxidized two carbon molecules attached to the coenzyme A and form acetyl CoA. This process generates 1 NADH which is equal to the 3 ATP.

During the TCA cycle, each molecule of the acetyl CoA oxidized to generate ATP  and carbon dioxide. This cycle produces 1 ATP, 1 FADH2, and 3 NADH. The total ATP production through this cycle is Approximately 12.

Thus, the correct answer is - 14 or 15 ATP.

Smaller muscle groups with a similar functional ability might include the ____________ major which acts as synergist in producin
Oksanka [162]

Answer:

Smaller muscle groups with a similar functional ability might include the antagonist major which acts as synergist in producing the same action as the agonist.

example : the biceps and triceps muscles of arm, work together as agonist and antagonist respectively.

The biceps helps to lift up or flexes the forearm and the triceps helps to extend it.

Explanation:

many muscles work together to make an action happen.

the muscle who is involved in an action principally, is known as prime mover or Agonist muscle.

Antagonist muscle does the opposite action  of the agonist muscle.

antagonist also helps in-

  1. maintaining the body posture or position.
  2. controls the rapid movements.

like, to move a bone , the muscles attached to it work together to make a movement happen. like- to lift up a arm, agonist or prime mover muscles helps to lift up or flex the arm and the antagonist or synergist muscle helps to extend it.
