Chromosomes are composed of deoxyribonucleic acid (DNA) mole
There are mainly two molecules that function as genetic material in living organisms.
These are ribonucleic acid(RNA) and deoxyribonucleic acid(DNA).
The organisms having DNA as genetic material require packaging of DNA as it is a long polymer of deoxyribonucleotides.
In the case of human beings, the length of DNA in a cell is approximately 2.2 meters which is very large as compared to the size of the nucleus( approximately 10^-6 meters).
So, the DNA has to be made compact for it to be present inside the nucleus of a cell.
Therefore, the DNA present inside the nucleus of a cell undergoes coiling and compaction through several stages before finally becoming a chromosome, which is shown in the adjoining diagram.
Thus, chromosomes are composed of deoxyribonucleic acid (DNA) molecules.

I would say that many of our heritable traits are <span>influenced by several genes and by the environnement.
It's, for the biggest part, because of the mutations. You have your heritables traits thanks to your mom and your dad. But a mutation caused by either several rays like ultraviolets or chemicals can changed your traits.
Hope this helps !

Answer:
a. Nothing happens because the two solutions are isotonic to one another.
Explanation:
Two solutions of the same molarity are separated from each other by a membrane that allows water molecules but not the glucose or sucrose to move across it. Movement of water across the selectively permeable membrane occurs only when two solutions have different concentrations of solutes. In that case, water moves from a hypotonic solution towards a hypertonic solution. Since both sucrose and glucose solutions have the same tonicity, there would not be any change in the solution.
