Answer:
a). At least one intron must be present in gene X.
b). At least two intron must be present in gene Y
c). It is impossible to determine whether there are any introns in gene Z.
Explanation:
Introns may be defined as the segments in the RNA molecule or the DNA molecule that does not code for proteins and they interrupts the sequences of each of the molecules.
In the context, we get :
a). In the gene X, at least one of the intron is present. Sometimes more than one introns may also be present. Due to slicing, we get one band less in the cDNA which is made from the mRNA.
b). In dene Y, at least one intron is present. Sometimes more than one introns are present inside the gene Y. In this case we get two bands less in the gene due to slicing.
c). In gene Z, it is not possible to determine the number of introns present in them. In genes X and Y, the Haelll enzyme is present in the intron. Therefore we get less of band after splicing the mRNA to cDNA.
Answer:
A plant's stem is what the plant uses to carry water and nutrients up or down. It also supports the plant and conducts glucose to other parts of the plant.

Answer:
Yes.
Explanation:
Yes, the people of a culture can eat a diet that is normal for their culture if they want to follow the Kemper diet because there are a lot of natural foods are present in the culture. Kemper's diet is heavy on fruits and vegetables and relies on natural foods so the people has a large number of natural foods in their culture so by eating that natural foods they can follow the Kemper diet.
Answer:
The ecomorph concept is a term first coined by Ernest Edward Williams in 1972 which he defined as a “species with the same structural habitat/niche, similar in morphology and behavior, but not necessarily close phyletically.”
