nignag [31]

Answer:

When you sit on a plane for 6 hours without moving, blood accumulates in your veins, and the moment you get up, gravitational forces affect venous return, cardiac output, blood pressure, and venous pressure. That way, when you're sitting on a plane, the gravitational force is the same at the upper and lower extremities, such as the chest, abdomen, and legs, causing venous blood pressure and volume to be evenly distributed throughout the body. However, when one gets up, one becomes dizzy because of abnormal regulation of blood pressure. This is because gravity causes blood to accumulate in the lower extremities (veins of the legs and trunk). This lowers the blood pressure and the blood that the heart pumps. By causing blood to accumulate in the lower extremities, and as venous compliance increases, the veins expand with blood that causes the volume of blood to shift in the veins. This increases the volume and venous pressure in the lower extremities when standing. And the volume of thoracic venous blood is less and less central venous pressure. This leads to a decline in stroke volume. Cardiac output and mean arterial pressure also decrease as left ventricular stroke volume decreases, reducing pulmonary venous return. Decreased standing blood pressure, referred to as orthostatic or postural hypotension. Thus, lowering blood pressure decreases cerebral blood flow, which means less range of blood in the brain causing dizziness.

In which of the following ways are DNA and mRNA different?
Tcecarenko [31]

Answer:

DNA:

Dexoyribonucleic acid is the genetic material of almost all the organisms except some virus. DNA contains deoxyribose sugar that lacks 2'OH group on second carbon. The nitrogenous base pair of DNA are adenine, guanine, thymine and cytosine. DNA cannot acts as an enzyme.

RNA:

Ribonucleic acid is present as genetic material in few viruses only. RNA contains oxyribose sugar that has 2'OH group at second position. The nitrogenous base pair of RNA are adenine, guanine, uracil and cytosine. RNA can acts as any enzyme in biological reactions.

Compare the wind speeds of the edge of a hurricane on earth and the edge of the great red spot on jupiter what is your conclusio
Illusion [34]

Answer:

Jupiter is approximately 318 times bigger than the earth. So, it is expected that its hurricanes would be very massive as well.

Explanation:

A hurricane is a tropical cyclone, a storm with a very violent wind. It is labeled a cyclone because of its cyclic nature.

The Great Red Spot of Jupiter is a giant storm about twice as large as Earth, which in its southern hemisphere orbits the globe. This at least twice the speed of the most dangerous and most destructive hurricanes on Earth, which can produce wind speeds of approximately 280 km/h.

So it means that if there were to be a great red 'jupiterian' spot on earth it would blow the earth away.

Cheers
