Explanation:
Answer:
TYPE OF LIQUID SUBSTANCE RECEIVED
Explanation:
The independent variable in an experiment is the variable that the experimenter deliberately changes or manipulates in order to bring about a response in the dependent variable/measured variable.
In this experiment, the TYPE OF LIQUID was changed for each group of plant in order to see how it affects how the plants grew. Hence, the TYPE OF LIQUID is the independent variable while the dependent variable is the plant growth, which is dependent on the independent variable.
Answer:
migration is brushing hair
putting a puzzle together is trial and error
getting hungry before lunchtime is a conditional response
brushing your hair is a habit
eye blinking is a reflex.
Explanation:
The answer is B. Precipitin Test.
Answer:
Enzyme- Peptidase/protease
Explanation:
According to this question, a student is conducting an experiment to determine the roles of molecules in metabolic processes such as digestion. Based on what she found out that the molecule, which itself can be broken down into amino acids, can also break down proteins into amino acids, this suggests that the molecule being described is a PROTEOLYTIC ENZYME.
This is because an enzyme is made up of proteins which can be denatured or broken down into its simplest unit (amino acids) and also, a substance that breaks down amino acid is said to be PROTEOLYTIC.
However, another observation that the molecule is found in high concentrations in the small intestine was made, hence, the enzyme is a PEPTIDASE OR PROTEASE, which are secreted into the small intestine by the pancreas to aid digestion of proteins.
