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.
The branch of the posterior descending artery that supplies blood to the inferior chamber of the heart. The LMCA supplies blood to the left side of the heart.
<h3>What is the arterial network?</h3>
The circulatory system, also known as the vascular system, is made up of the blood and lymphatic vessels that transport fluid throughout the body. In addition to delivering oxygen and nutrients to the tissues and eliminating waste from the cells, the arteries and veins move blood throughout the body.
<h3>Which organ has arteries in it?</h3>
The blood vessels known as arteries carry oxygen-rich blood from the heart to all of the body's cells. They are a part of your cardiovascular system, which circulates your blood. For your body to receive nutrition, hormones, and oxygen, they are necessary.

The peer review is the process of the review by the other members involved in the study of the same topic. The peer review increases the validation of the paper and is ready to be published after wards. Hence, after the peer review is completed and the claim present in the paper stand to be true, then the paper is ready to publish and the nest step must be the publishing of paper.
the answer is the cell membrane
<span>b. photosynthetic organisms provide energy for other organisms on earth.
B is the most suitable answer as photosynthetic organisms get their energy from the sun, and other organisms get their energy from photosynthetic organisms, so the sun is the source of energy for all life.</span>
