A bacterial promoter sequence must be included. The coding exons control the actual production of the protein that the gene codes for; meanwhile, the promoter sequence serves to initiate transcription of the specific genes. Promoters are included upstream of the DNA molecule at the start site of the gene.
Answer:
The correct option is A. Cooler, more dense material sink while warmer, less dense material rises.
Explanation:
Convection can simply be described as the transfer of heat energy among molecules or substances. Convection will occur if molecules of liquid or gas are given rough supply of heat. Hot liquids or gases would have the following properties:
- Their density would be less.
- They would have the ability to rise.
Whereas the cooler molecules will have the following properties:
- Their density would be more than the hot molecules.
- They would have the ability to sink.

Correct answer: D). Damage to nerves that control the stomach
Gastroparesis is a medical condition in which the stomach is unable to empty its food. it is mainly caused due to damage caused to the vagus nerve, it is a nerve that regulates the digestive system.
Due to the damaged of vagus nerve the muscles of the stomach are not able to contract, which prevent the movement of food by the digestive system and results in gastroparesis.
The major cause of gastroparesis includes uncontrolled diabetes, multiple sclerosis, gastric surgery that cause injury to the vagus nerve and use of antidepressants etc.
