Allele An1 shows full activity in anthocyanin production and thus are red in color

Allele An2 shows null activity in anthocyanin production and thus are ivory in color

Genotype of pure-breeding red snapdragons is An1An1

Genotype of pure-breeding ivory snapdragons is An2An2

F1 generation -

An1An1 x An2An2

An1An2, An1An2, An1An2, An1An2

F2 Generation -

An1An2 x An1An2

An1An1, An1An2, An1An2, An2An2

Living organisms cannot use heat to provide the activation energy for biochemical reactions because

Otrada [13]

Considering the following;

I. Heat is not readily available to all living cells.

II. Heat at excessive amounts denatures proteins.

III. Heat does not provide the activation energy for their reactions.

IV. When a critical temperature is reached, proteins no longer function

Answer;

I and IV

Explanation;

Living cells cannot use heat to provide the activation energy for biochemical reactions because heat is not readily available to all living cells and also when a critical temperature is reached, proteins no longer function.

Too much heat can kill an organism by rendering its organelles, cells, tissues and organs permanently inoperable and un-salvageable. The same process can be observed in tissues at low temperatures, and is the cause of frostbite. This is because enzymes are denatured by high temperature and inactivated by low.
