B. proto-oncogenes.
C. cancer genes.
D. telomeres.
Answer:
The correct answer is option B. "proto-oncogenes".
Explanation:
Tumor suppressor genes and proto-oncogenes are two types of genes that can cause the development of cancer cells if they suffer a mutation. The main difference between tumor suppressor genes and proto-oncogenes is the way they cause cancer. If tumor suppressor genes are inactivated they produce cancer cells, while if proto-oncogenes are activated is when they produce cancer cells.
CFC (chlorofluorocarbon), including freon, is used as the aerosol propellant. An aerosol is a suspension in the gaseous form of solid or liquid particles. When these compounds reach the stratosphere, UV light affects them and they release chlorine atoms. Chlorine atoms are capable of breaking down ozone molecules. With fewer ozone molecules, the ozone layer becomes thinner and harmful UV light passes through it causing many health problems, such as skin cancer.
In the digestive tract, mouth is the primary location where enzymes act to break the bonds between disaccharides into monosaccharides.
It consists of the gastrointestinal tract along with the accessory organs which are present in digestion process . It involves the breakdown of complex food into smaller components which can be easily assimilated and absorbed by the body.
The digestion process has 3 phases: cephalic phase , gastric phase and intestinal phase.Cephalic phase begins with secretion of gastric juices from gastric glands in response to sight and smell of food.It involves chewing and chemical breakdown of food by the action of digestive enzymes ,saliva in the mouth contain enzymes like lipase and amylase which are secreted by the salivary and serous glands present on the tongue.

Answer:
Mouth.
Explanation:
Mouth contain saliva.Saliva have enzyme salivary amylase (ptyline) which breakdown disaccharides(starch) into Monoscchrides .About 30% disaccharides(starch ) digeation occur in mouth.

C: could the gene for resistance increase the yields of the crop as compared to unmodified varieties?
D: Could the gene for resistance negativity affect the genetic diversity of the crop itself?
