Answer:
D. Each enzyme can catalyze a wide variety of different reactions
Explanation:
Each enzyme can only catalyze a few, specific types of reactions.
Since enzymes and substrates are very specific to one another, enzymes cannot catalyze a wide variety of reactions.
If a substrate is not the correct one that fits in the enzyme's active site, a reaction will not occur.
So, each enzyme can only assist in a few reactions.
The correct answer is D. Each enzyme can catalyze a wide variety of different reactions
Answer:
It is true to say that by using cuttings, exact genetic characteristics can be maintained, because the cuttings retain the same genetic information about the plant from which they were extracted.
Explanation:
Cuttings are buds or branches extracted from a plant to obtain a plant of the same species, through a type of asexual reproduction.
Once separated from the "progenitor" plant, the cutting is provided with a suitable medium for growth, and will have the possibility of growing roots, developing and growing as an independent plant, with the same genetic characteristics of the original plant, as if it were a clone.
In this reproductive process, man intervenes.
