Your heart has four valves. Normally, these valves open to let blood flow through your heart, and then shut to keep it from flow

Ulleksa [173]

Regurgitation influences the flow of blood by mixing the oxygen-poor blood with the oxygen-rich blood. Due to this, the heart has to pump more to oxygenate the entire body, leading to the rapid, and fluttering heartbeat. The tissues get oxygenated but regurgitation could be fatal, as the heart cannot function overtime forever.

Valve prolapse influences the flow of blood when the flow of blood backs up. This leads to an irregular or racing heartbeat. Even at certain occasions, the blood can flow back to the lungs. However, there is not a huge influence in the oxygenation of the body tissues.

Stenosis makes the ventricles to pump overtime to get enough blood through, and in the process, the ventricles thicken. This functions for a while, however, it will result in heart failure as the heart cannot do it for entire life. The tissues are oxygenated, but it will be an issue due to overtime.

How a change in glycoproteins affects a cell’s ability to maintain homeostasis

Licemer1 [7]

Explanation:

Most of the cell surface receptors and glycoproteins. These glycoproteins have active sites that recognize specific signals, like hormones, that initiate secondary signaling pathways inside of the cell, in response to the external signal. This is how cells respond to environmental stimuli.

If a change in glycoproteins makes them unable to bind signaling molecules (like hormones) or makes them permanently bind these molecules, there will definitely be a defect in how the cell responds to external stimuli. The cell will be, for example, be unable to respond to insulin in case of elevated blood sugar levels as is the case with diabetics.

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 Punnet's square result of crossing two plants that are heterozygous for both traits is as in the attached image.

AaBb x AaBb

Possible Offspring

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
