<h2>Answer:</h2>
The correct statement is option A which is, "A gene is a segment on the DNA. DNA is wrapped in proteins to form a chromosome".
<h3>Explanation:</h3>
- A gene is the part of DNA in the nucleus which encodes for the specific trait in the body. DNA is the nucleotide sequence which is the blue print for the whole organism. It contains genes for all the structures and functions in the body.
- So it is very long sequence containing the million of genes. So in nucleus it is present in compress form. It is wrapped on the histones proteins and condense and supersondense into a specific structure which is known as chromosome.
Answer:
they form long chain-like molecules.
Explanation:
they combine using covalent bonds, and give off water molecules.
Answer: The probability is 100%.
Explanation: The chromosome X is related to gender. A man carries two different chromosomes (XY) and a woman carries two similar chromosomes (XX). The offspring of a couple will inherited:
- If it is a boy, he inherites the chromosome Y from his father and X from his mother;
- If it a girl, she inherites X from her father and X from her mother;
In the question, the woman is color-blind, which means she carries the recessive alleles: 
The man, on the other hand, is normal, so his X-linked genotype will be: 
.
Now, since they have a daughter, she inherited her double X from each of her parents, which means she inherited one 
from her mother and one 
from her father.
So, the daughter's genotype can only be heterozygotic in other words, the probability is 100%.

Once, a physician accept to treat a patient, their relationship will continue to exist until the patient no longer needs the physician, then the relationship will end naturally. But in a situation where the relationship has to come to an untimely end, the physician must avoid abandonment claim by giving sufficient notice of withdrawal to the patient, relatives or responsible friends and guardians of his patient in order to secure another physician.
