Organisms adapt to changes in their surroundings.
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.

Answer:
I believe the answer would be line D
Explanation:
Line D is where the line escalates the fastest, so I believe line D is where the object's speed is the fastest
The process of the development of reproductive cells in males is called Spermatogenesis. Spermatogenesis develops immature germ cells into mature sperm cells. Oogenesis is the process of the development of reproductive cells in females. Fertilization happens when the sperm and egg cells unite.
Answer:
In the ecosystem, the tides of the water rise in each figure. In figure 4, there is an increase in land animals present, and a lower amount of aquatic animals present. In the first figure, there are no birds, however there are multiple in the rest of the figures, this is possibly due to migration in the winter or that the ecosystem has drawn birds near. The types of plants change throughout each figure which is most likely to new adaptations such as more water available. The tides most likely rose because of more precipitation.
