1. A student conducted research about the roles of molecules in metabolic processes
Vlada [557]

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.

There are two basic ideas that are key to Darwin's Theory of Evolution. The first is that present day species are descendants of
Svetradugi [14.3K]

Answer: Natural selection is the driving force to explain the mechanisms  of  evolution.

Explanation:

◼In a given population Organisms usually produce more offspring than what the environment can support.  

◼ VARIATION, is driving force  for  the manifestation of  sustainable inheritable characteristics from parents in a given population.

◼ Organisms, who acquired certain characteristics from variation; tend to survive than others, and therefore pass these inheritable characteristics to their offspring.

◼There is competition for the available resources among the offspring which leads to a stable population in size after a period of time.

◼Darwin deducted that, variants of best adaptation will be selected for by natural conditions operating in the environment of the population at that particular period (natural selection).Therefore natural selection takes place, and the organisms with best variation will have selective advantage above others. Consequently they have higher survival rates compare to others in the population.

This is   survival of the fittest by natural selection , this is the second conclusion  of Darwin theory.
