Answer:
This disorder is caused by a recessive allele, its inheritance is sex-linked.
Explanation:
The disorder affects boys born to unaffected parents, this means that at least one of them has to be a carrier of the allele which causes the disease. So, if the allele was dominant, it would express in parents and sons. But, in this case, only is expressed in sons, so it can´t be dominant. Moreover, this condition has a sex-linked inheritance because it is always seen in boys and never in girls. This happens due to boys only have an X chromosome, so if they inherit the recessive allele of the disease, they will express it. On the other hand, girls have two X chromosomes, so if they inherit one copy of the recessive allele, they will be carriers and they won't be affected.
This disorder is never seen in females because they need to have two copies of the recessive allele. However, to have double copy, they should inherit one copy from their mothers and one copy of their fathers, but boys with the allele are affected and they die in early teens without having progeny. Therefore, a girl can't have a "carrier-father", so they will never have two copies to express the disorder.
D) providing the energy for the duplicate cells
Answer:
Decrease in competition from other plants.
Explanation:
Decrease in competition from other plants is the environmental factors likely leaf to the exponential growth seen in fireweed after the Yellowstone wildfires because decrease in population from other plants will lead to a particular species dorminating a particular geographical area and this dorminating species are Dorminant when competition has been reduced by wild fire and this will lead to exponential growth where the available resources will be abundance or unlimited or resources increases.
If denaturation occurs (extreme temperature change or pH changes), the enzyme will not be reusable! The structure of the enzymes are not changed. As a result of this, enzymes will be used again and again to bind onto another substrate molecule and catalyze the reaction once again.
Answer:
Option (3).
Explanation:
Batch culture may be defined as a type of culture which are refereed as stack and operated as influx of the reactant up to the maximum level. This technique is generally used to grow the micro organisms.
The cell mass do not decrease or increases as the cell divides in the batch culture. The new batch are added during the culturing process. The cell mass remains constant in batch culture.
Thus, the correct answer is option (3).
