Answer:
Explanation:
we have three strains.
the first is the wild type which has tryptophan mRNA which gets degraded rapidly and tryptophan synthase which is stable. therefore, in the presence of tryptophan, no new mRNA is formed and whatever tryptophan synthase was present would be diluted out as cells continue to divide.
Strain A has stable mRNA and stable tryptophan synthase. so since the mRNA is present, new enzyme will continue to form from it. However, since no new mRNA is formed, the enzyme activity will get diluted as cells divide, but at a much slower rate than the wild type.
in Strain B , synthase is rapidly degraded and no new mRNA is formed. so the tryptophan synthase activity would decrease drastically.
Answer:
<em>Light-dependent reactions</em>
<em></em>
Explanation:
Photosynthesis occurs in two stages: light-dependent reactions and light independent-reactions. This last stage is often called Calvin cycle.
The diagram shows reactions occurred in the thylakoid membranes which are located inside the chloroplasts. Therefore, we can identify that these reactions are the light-dependent reactions. During this part of photosynthesis, the energy from the sunlight is absorbed by a pigment called chlorophyl (Chl). Then, it is sequentially coverted into chemical energy stored in the form of molecules: NADPH (nitotinamide adenine dinucleotide phosphate) and ATP (adenosine triphosphate).
Answer:
The answer to your question is: two
Explanation:
Sucrose is a disaccharide composed by two disaccharides: glucose and fructose. Sucrose is found in plants. Its molecular formula is:
C₁₂H₂₂O₁₁
Exercise and reactions to exciting stimuli include increased activity in the sympathetic, and decreased activity in the parasympathetic divisions.
<h3>
What is the sympathetic nervous system?</h3>
The autonomic nervous system includes the sympathetic nervous system. It might be referred to as the "automatic" nervous system because it controls many processes that we don't have to think about. This can affect a variety of bodily processes, such as the regulation of our heart rate, blood pressure, digestion, urination, and perspiration. For its role in reacting to risky or stressful conditions, the sympathetic nervous system is best known.
<h3>
What is the parasympathetic nervous system ?</h3>
One of the two functionally separate and perpetually active divisions of the autonomic nervous system is the parasympathetic nervous system (PNS) (ANS). It opposes the sympathetic nervous system, which is the other (SNS). In calm "rest and digest" situations, the parasympathetic nervous system predominates, whereas the sympathetic nervous system activates the "fight or flight" response in stressful circumstances. The major functions of the PNS are to regulate body processes like digestion and urine as well as to store energy for later use.
Hence, Option B is correct. Exercise and reactions to exciting stimuli include increased activity in the sympathetic, and decreased activity in the parasympathetic divisions.
