Answer:
b) from a region of high pressure to a region of low pressure
Explanation:
Blood flow is measured in blood volume per unit time. It is the movement of blood through an organ, tissue or vessel. It is initiated when ventricles in heart contract leading to its ejection at high pressure. Major arteries receive this blood and they further transport it at high pressure to smaller arteries, arterioles and capillaries. Hence arteries have thick walls to withstand this pressure. The pressure decreases when blood reaches to veins hence their walls are not that thick. Hence, blood flows from a region of high pressure to a region of low pressure.
Answer:
I would say B is the answer.
Explanation:
An applied force is a force that is applied to an object by a person or another object. Example: pushing a box to the other side of a room.
A normal force is a force that surfaces exert to prevent solid objects from passing through each other. Example: resting a book upon a table.
Drag is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This doesn't really match the force we use.
However, an attractive force is a force by which one object attracts another. Example: two magnets pulling/colliding together. This is a good example of a force we exert on objects when it is pulled toward us.
Guard cells are located in the leaf epidermis and pairs of guard cells surround and form stomatal pores, which regulate CO2 influx from the atmosphere into the leaves for photosynthetic carbon fixation.
Stomatal guard cells also regulate water loss of plants via transpiration to the atmosphere.
