Answer:
A. an increase in skin cancer among humans
Explanation:
The ozone layer is a part of the stratosphere that absorbs most of the Sun's ultraviolet(UV) radiation.The ozone layer contains a lot of ozone present in it and it serves as a shield. The radiations are harmful to the body and pose serious health risk when humans are exposed to them.
Such risks include cancer of the skin due to the skin being the part of the body at a greater risk of exposure.
Answer:
Extrachromosomal or cytoplasmic inheritance
Explanation:
Extrachromosomal or cytoplasmic inheritance refers to hereditability transmission controlled by cytoplasmic genes.
This form of inheritance lays in genes that are out of the nucleus. Information for some characters is placed in organelles in the cytoplasm, such as mitochondria and chloroplasts. These organelles have a well-defined portion of the total cellular genome.
Although mitochondrial inheritance is mostly maternal, recent studies have demonstrated that it might also be paternal.
Sperm cells hardly carry mitochondria, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this DNI, the whole progeny of the mutated woman will be affected, as they will get the mother´s mitochondria carrying the mutation. On the contrary, if there is a man affected by a disease caused by a mutation in mitochondrial DNI, non of their descendants will get the disease.
