Hi,

Attached is solution diagram. You can see that true breeding means both have same alleles for purple PP and white WW flowers.

They were crossed to produce hybrid plants that all had purple flowers PW because purple was the dominant trait.

However, upon self fertilization of those hybrid plants, both purple and white flower plants were produced in 3:1.

Hope it helps!

Dvinal [7]

Answer:

Although humans and animals (technically “non-human animals”) may look different, at a physiological and anatomical level they are remarkably similar. Animals, from mice to monkeys, have the same organs (heart, lungs, brain etc.) and organ systems (respiratory, cardiovascular, nervous systems etc.)

Humans have a heart with two atria and two ventricles that pushes blood in one direction. Some animals have hearts similar to humans but, other animals have only one atrium and one ventricle or a cardiovascular system that can push blood in two directions.

Memory for stimulus sequences distinguishes humans from other animals. Summary: Humans possess many cognitive abilities not seen in other animals, such as a full-blown language capacity as well as reasoning and planning abilities.

Living cells cannot use heat to provide the activation energy for biochemical reactions because ________. Which choice(s) comple
postnew [5]

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.
