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.
Explanation:
After another enzyme (a DNA helicase) has seperated two orginal strands of DNA, the polymerase moves along the template strand and polymerizes free nucleotides into a new antiparallel strand. ... DNA ligase joins pieces of DNA together, mainly joins Okazaki fragments with the main DNA piece.
I think this is what you are referring to.
Hope this helps.
The land edge that is affected by marine processes is known generally as the coast
- A sea's shore is the area of land there. The coastline is the area of a shoreline where land and water converge.
- Coastlines are shaped in part by currents, tides, and waves. The ground is eroded or worn away when waves crash upon the shore.
- Despite making up only around 8% of the land on Earth, coastlines contain about 26% of all biological diversity.
- This wonderful environment, which is home to many different species of natural communities, is home to seabirds, clams, crabs, starfish, anemones, fish, kelp, and marine mammals, among many other creatures.
- Though it can also be a tough and challenging environment, since it is frequently altered by erosion and tides as well as pounded by waves and sea spray. Typically, there are three types of coasts: rocky, sandy, and muddy.
