In molecular biology, a vector is a DNA molecule that is used as a vehicle to transfer foreign genetic material into another cell.
The four major types of vectors are plasmids, viral vectors, cosmids, and artificial chromosomes.A vector is a living organism that spreads infectious agents from infected animal to infected animal. Arthropod vectors include mosquitoes, ticks, flies, fleas, and lice. The haematophagous arthropod definition, which defines vectors solely as blood-feeding arthropods such as mosquitoes, ticks, sandflies, tsetse flies, and biting midges, is similar. Vector quantities include displacement, acceleration, force, momentum, weight, the speed of light, a gravitational field, current, and so on.

No, heterotrophs do not covert solar energy into chemical energy. Heterotrophs are organisms, like humans, that find their own food. They can not physically make their own food because they can't use the process of photosynthesis. So, heterotrophs hunt or gather their own food.
The answer D sorry if I’m wrong
Answer:
While digesting food, the liquid food then enters the small intestine where the acid is _neutralized_, and enzymes break down fat, protein and carbohydrates for absorption by tiny hairs called villi.
Explanation:
The small intestine is where most chemical digestion occurs. Most of the digestive enzymes that act in the small intestine are secreted by the pancreas and enter the small intestine through the pancreatic duct.
The enzymes enter the small intestine in response to the hormone cholecystokinin, which is produced in the small intestine in response to the presence of nutrients. The hormone secretin also causes <em>bicarbonate to be released into the small intestine from the pancreas in order to </em><em>neutralize</em><em> the potentially harmful acid that comes from the stomach.</em>
This is to protect the cells lining the small intestine from the acid.
Answer:
Nucleic Acids Proteins Carbohydrates
Lipids
Explanation:
All organisms need four types of organic molecules: nucleic acids, proteins, carbohydrates and lipids; life cannot exist if any of these molecules are missing.
