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.
Answer:
The flowers and moths experienced the same allopatric speciation events during their history.
Explanation:
Co evolution may be defined as the process of the evolution of more than two species together that oppositely affects the evolution of each other. The natural selection provides the base for the co-evolution.
The co evolution generally occurs in the flowers and its pollinating species. The moth and the flower speciation represents the co evolution because both evolution are affected by each other. They have experienced the co evolution due to the allopatric speciation event and leads to teh genereation of the specific change in the characteristics.
Thus, the correct answer is option (e).
Answer:
Option D, DNA from a dead organism can become active in another organism
Explanation:
It has been established by a famous researcher Soren Overballe-Petersen that some parts of our body never die. This is because the even though the organisms die, its genetic components such as DNA or part of it remain active and if these are fed into any culture , they are adopted by the genomes of the cells in the culture.
Hence, option D is correct
