Which types of cells in the body would you expect to require the most atp? support your answers with evidence?

rewona [7]

The answer is muscle cells. This is because they are responsible for either voluntary movement (skeletal muscle) or involuntary movement (smooth muscle). This movement requires energy to power the movement of the actin and myosin action that is the core of every muscle. Each myosin has an ATP-binding site.

In the spotted tulip, white flowers are dominant to yellow (gene Y), and axial flowers are dominant terminal flowers (gene T). E

aleksklad [387]

Answer:

9/16 A_B_ White colour, axial flower

3/16 A_bb White colour, terminal flower

3/16 aaB_ Yellow colour, axial flower

1/16 aabb Yellow colour, terminal flower

Explanation:

Let the flower colour allele be represented by A and the flower position by B. The dominant white colour would be A while the alternate version (the yellow colour) would be a. Also, the dominant axial flower position would be B while the alternate terminal position would be b.

The way you breathe and the way your heart beat changes when you run fast.

CaHeK987 [17]

Answer:

Your body sends a message to the lungs and tell the lungs to breathe in more oxygen so that the oxygenated blood can travel to the muscles oxygenating the cells within that specific muscle and giving them energy to use the sugars stored in fat or food from digestion. The heart beats faster so that the cells supply keeps up and continues to beat fast for that specific diration of time until your breathing slows down and it no longer needs to work as fast to supply the muscles with as much blood.
