Answer:
d. Ao x oo
Explanation:
The other crosses with A would all result in complete dominance because the alleles (other than A) from the other parent are dominant. Because option D. crosses a h o m o zygous parent with a recessive trait, the cross could produce a child with blood type A.
<h2> ANSWER</h2>
<u>B.</u><u> </u><u>carbonate shells are dissolved in deep water</u>
Carbonate sediments are rare in deep sea sediments because the <u>carbonate shells are dissolved in deep water</u><u>.</u>

The cell that provides life with chemical energy. Light energy is converted by photosynthesis into chemical energy that is stored in glucose, and this energy is then released during cellular respiration to create ATP.
<h3>What does the term "cellular respiration" mean?</h3>
While cells are aerobic respiration, oxygen may be present or not. But, because the cell seems to "respire" by consuming molecular oxygen (as an electron acceptor) and releasing carbon dioxide, the process is essentially known as "cellular respiration" (as an end product).
<h3>What happens during cellular respiration?</h3>
ATP is created during cellular respiration as a reaction product between glucose and oxygen. Water and carbon dioxide are released as by products. The three stages of aerobic cellular respiration are glycolysis, an anaerobic process, and the Krebs cycle.

Multi cellular organisms are made up of billions of cells each specialized to a unique role and these cells are organized into structural and functional units such as tissues and organs.
For each cell and organ to function optimally, it requires oxygen and nutrients and needs carbon dioxide and metabolic waste taken away in a continuous, never ending process.
<span>A mechanism is needed to accomplish the important function of transporting the relevant materials to and from the cell. The circulatory system fits this bill splendidly. It is a specialized organ system which allows blood and lymph to flow through the entire body carrying nutrients such as glucose, amino acids and electrolytes as well as oxygen to each cell, at the same time carting away carbon dioxide and all sorts of metabolic waste over to excretory organs to be expelled from the body.

Answer:Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size.
