Answer:
<h2>mRNA, tRNA, and rRNA are all produced by transcription.</h2>
Explanation:
Trascription is the process through which RNA molecules are produced from the DNA template with the help of RNA polymerase/ RNA pol holoenzyme and various other factors. One strand of DNA works as a template, and according the the sequence in DNA, RNA synthesis occur in complementry way.
All type of RNA (mRNA, tRNA, and rRNA ) molecules are produced by transcription.
Answer: Exercise causes the heart to pump blood into the circulation more efficiently as a result of more forceful and efficient myocardial contractions, increased perfusion of tissues and organs with blood, and increased oxygen delivery. Aerobic exercise trains the heart to become more efficient.

Vacuole being cellular organelle found in cells serves few important functions for the cells. It's usually the biggest cell organ within the cell. Its main function is the store nutrients and waste materials. It additionally functions to take care of the correct pressure inside the plant cells to provide structure and support for the growing plant.
Further Explanation:
The bubble-like structures present in a cell is known as the vacuoles. These vacuoles may store food or any kind of nutrients that a cell may require to survive, not solely this but vacuoles will even store waste product, so that the rest of the cell is protected against contamination. Vacuoles are membrane(tonoplast) bound sacs that are present within the protoplasm of the cell. There are many functions of vacuoles. the inner fluid within the cavity is understood as the cell sap. In mature plant cells, the vacuoles are of a bigger size and provide structural support to the cells. The vacuoles additionally perform as the storage organ, waste disposal organ, protection organ and for growth. Some vacuoles store toxic substances and waste materials that taste Bitter to the insects. The ability to regulate the turgor pressure in a plant cell is the important characteristic function of the central vacuole. Turgor pressure determines the rigidity of the cell.
The above-named functions are the few functions of the vacuole.

Because if there an increase win solute extracellularly that will pull most of the water out of the blood vessels and a function of the antidiuretic hormone is to increase blood volume by reabsorbing water from urine and maintaining electrolyte balance so blood pressure and volume remain constant or at equilibrium
Fructose-1,6-bisphosphate is a feedforward <u>allosteric</u> activator of liver pyruvate kinase.
<h3>What is the role of fructose 1/6-Bisphosphate?</h3>
A crucial enzyme in gluconeogenesis is fructose 1,6-bisphosphatase (FBPase). It is a possible target for drugs used to treat type II diabetes. Additionally, the protein is linked to a rare genetic metabolic disorder, and certain cancer cells lack the activity of the enzyme FBPase, which encourages glycolysis and aids in the Warburg effect.
The following reaction is catalyzed by FBPase. The enzyme is controlled allosterically by several small molecules, including AMP and fructose-2,6-phosphate, which are negative regulators, and ATP, which is a positive regulator. Pyruvate kinase activity is activated when FBP attaches to the allosteric binding site on domain C of the enzyme. This conformational shift is brought on by a change in the enzyme's structure.
