A pan heating on the stove is the best example of heat transfer through conduction
Hope this helps.
Answer:
OPTION C )TRP
trp operon is an example for anabolic operon. It generally codes for enzymes responsible for the synthesis of tryptophan, an essential amino acid
Answer: The enzymes are important to the digestive system because they help in BREAKING DOWN of food substances that contains fat, carbohydrates and proteins.
Explanation:
In the process of digestion, several substances are secreted into the duodenum which is the first part of the small intestine. The pancreas, through the pancreatic duct, secretes pancreatic juice. This juice contains several digestive enzymes which include:
--> Amylopsin- This helps in the breaking down of starch( CARBOHYDRATES) to maltose.
--> trypsin: this is a protease that helps in the breaking down of PROTEIN into polypeptide.
--> Lipase: This helps in the breaking down of FAT to carboxylic acids and glycerol.
All the above enzymes of the pancreatic juice require an alkaline medium to work in. This is provided by the bile which is secreted in the fall bladder.
Answer: The correct answer is B) Superconductor, conductor, semiconductor, insulator.
Resistivity to the flow of electrons is inversely related to the conductivity of the material. This means that more is the resistivity, lesser is the conductivity.
Superconductors are those materials, which have zero resistivity. Thus, they have maximum conductivity, conductors are those that have little resistivity, semiconductors have more resistivity than conductors, and insulators have maximum resistivity so they do not allow the electric current to pass through them.
Thus, B) is the right answer.
