Answer:
The gene that encodes ampicillin resistance.
Explanation:
The plasmid would contain the ampicillin resistance gene which gets expressed in the presence of ampicillin.
Radiation
The fire radiates heat and the human body absorbs said heat.
Answer:
A scientific model is a representation model for a certain scientific concept. Scientific models make it easier to study a phenomenon as they tend to model out the exact phenomenons.
A drawing of an skeleton would be unclear as the children might not be able to locate certain features in the drawing. For example, a certain joint could be missed by the teacher in the drawing or the child might not exactly be able to locate where the joint or bone is present.
But as the model will be more real to the actual skeleton system hence, studying through a skeleton will make it a lot easier to study the human skeletal system.
Answer:
Biocatalyst or enzyme
Explanation:
The Lactose is a disaccharide sugar or carbohydrate found in the milk and the milk products.
The breakdown of the lactase is very difficult but the presence of a protein molecule called lactase-phlorizin hydrolase or lactase makes the breakdown of the lactose int galactose and glucose easy.
Such protein molecules which increase the rate of reaction are called enzymes and since the breakdown of lactose is a biological process, therefore, the enzymes are also known as the enzymes or the biocatalyst they increase the speed of the reaction.
Thus, Biocatalyst or enzyme is the correct answer.
