Considering that chromosomes are structures that carry genetic meterial, what role do chromosomes and genes play in inheritance and the determination of traits.

Answer AND Explanation:

Chromosomes are thread-like structures found in the nuclei of cells. They contain the genetic material, the DNA. Chromosomes exhibit characteristics behaviour during cell division. Cell division ensure transmission of genetic material and contribute to inheritance from the parent to offspring when the chromosomes separate. Gene codes for a specific protein by specifying the order in which the amino acids are linked together, thus a gene determines the traits of an organism.

b would be the right answer

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
