The correct answer is valve vegetations and stenosis.
Rheumatic heart disease (RHD) is damage to one or more heart valves that is caused by an episode/episodes of acute rheumatic fever. The normal blood flow through damaged valves is interrupted. The heart valves are unable to function properly, so the blood may flow backward through stretched valves (not closed properly), or may be blocked due to scarred valves (not opened properly). Heart surgery may be required for this condition.
Pathology is the study of the cause and effect of diseases and sicknesses.
I would say D, as to observe the way that bipolar patients behave.
Answer;
The offsprings will be such that , a normal vision female, a heterozygous female, normal male and a colorblind male.
Explanation;
-Most X-linked traits in humans are recessive. One example of an X-linked trait is red-green colorblindness. Let (Xc) represent the recessive allele that causes colorblindness and (XC) represent the normal dominant allele. Females that are XCXC or XCXc have normal color vision, while XcXc females are colorblind. For males with; XcY are color blind, while those with XCY are have normal color vision.
Heterozygous female, XcXC
Normal male, XCY
The offspring of the parents, XcXC x XCY, are: XcXC (heterozygous female), XCXC( normal vision female), XCY (normal vision male), XcY (color blind male).
Answer:
To cleave DNA strands at specific nucleotide sequences
Explanation:

Atoms are the smallest building blocks of elements having the same chemical and physical properties of that specific element. Atoms combine together with the help of electrons, to form a little more complex entity like the molecules, crystals, liquids etc. Some molecules combine together to form a more complex entity like the DNA which is the most complex molecule. The whole universe is made out of these simple building blocks, including the human body.
