Answer:
provides food for embryo
Explanation:
The structure marked with an X in the figure below is called a stored nutrient reserve.
The seeds are basically formed by an integument (outer part, a stored reserve and the embryo (it is in the center of the seed), the embryo is the main creator of a new plant, for that, it needs a high load of nutrients that is provided by the nutrient reserve. In addition, the stored nutrient reserve protects the embryo from external factors such as solar radiation and freezing.
Antibiotics, are helpful for treating the common cold, however due to them being very powerful medicine, they are not highly recommended.
Answer:
Average max. elongation rate = modified RNA pol./ wild type RNA pol = 2/12 = 0.166 nucleotides per sec.
Explanation:
After treating the wild type and experimental RNA with amanitin solution, the amanitin actively binds to the active site of wild type RNA polymerase, inhibiting addition of nucleotides and also it interferes with the motility of RNA pol. along the DNA template, due to which their is a sharp decline in maximum elongation rate of mRNA. In case of experimental RNA polymerase, due to single base substitution the experimental strain is already having very low elongation rate, but binding of amanitin causes constraint on the motility of RNA polymerase through the DNA template, thereby decreasing the elongation rate. Average max. elongation rate = modified RNA pol./ wild type RNA pol = 2/12 = 0.166 nucleotides per sec.
...an area where a ecological succession has already happened.
A secondary succession would occur where an area has been burned down or has experienced an event that has destroyed the prior ecosystem completely.
