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: a nucleus is like a sun because it has planets surrounding it and it is the center of a solar system like a nucleus is the center of the cell. hope this helps you a little
Explanation:
The carbon dioxide carried in the blood is actually combined with water and carried in the red blood cells in the form of carbonic acid, which has a dissociation constant:
H₂CO₃ ↔ H⁺ + CO₃⁻
When the pH of the blood decereases, the concentration of H⁺ ions in the blood becomes high. This causes the equilibrium to shift backwards, as per Le Chatelier's principle. The H⁺ ions are converted back to carbonic acid and the pH is increased. The opposite occurs when the pH is too high.
Antibiotics killed bad bacteria . that means white blood cell resistant bacteria
Answer:
Option C, making ATP to power cell activities
Explanation:
In cellular respiration, the energy stored in food is converted to readily available energy form i.e ATP (Adenosine Triphosphate) molecule. During cell respiration, the cell breakdown the glucose (carbohydrate) molecule into carbon dioxide (CO2), H2Oand ATP (energy molecule).
ATP being an energy molecule act as a source of energy for all metabolic processes. Along with ATP , higher level energy molecules like NADH is also produced.
Hence, option C is correct
