Answer:

Horses have 64 chromosomes and donkeys 62, so when the two breed their mule offspring ends up with 63. Because this is an odd number, it's impossible for them to divide evenly into two. That means the mule cannot produce sperm and egg cells that carry exactly half the animal's chromosomes, as should happen.Aug 28, 2018

Which of the following is NOT a part of an ATP molecule? Select one: a. adenine b. ribose c. chlorophyll d. phosphate
Gnesinka [82]

Answer:

C (Chlorophyll)

Explanation:

Adenosine triphosphate (ATP) is an energy carrying molecule in all living cells. It is the usable form of energy by cells. Organisms are able to carry out cellular functions using the energy carried by ATP molecules. ATP like other molecules is made up of components that make up its chemical structure.

ATP is composed of three structural components; A five-carbon sugar called RIBOSE at the core of its structure, attached to a nitrogenous base called Adenine and phosphate group (three in ATP). The energy in ATP is released when it loses its phosphate component.

Chlorophyll is a pigment found in the Chloroplast of plant cells. It is another molecule that is made up of its own components e.g nitrogen, magnesium etc.
