Answer:
Reasons why Maria will have tissue ischemia:
1. Because of evident problems with her blood circulation, this means insuficent blood flow. This shows in the edema she has.
2. The ischemia can lead to hypoxia because of the lack of oxygen in the blood stream to reach to the tissue cells.
Explanation:
Ischemia is a health problem characterized by the lack of oxygen that the bloods transports to the tissues in the body.
Hypoxia is related to the unsuficient oxigen supply gettin to a certain regions of the body or to the entire body.
Answer:
The correct answer is - because 3×3×3 has the highest Surface area to volume ratio, diffusion in and out of the cell would be faster.
Explanation:
It is known that if the size of a sphere or cell increases, the volume is a cube, and the surface area is squared therefore volume increases faster than the surface area. If the volume is more and the surface area is less than diffusion will be less effective. diffusion takes longer and is less effective.
The decrease in the surface-to-volume ratio leads to diffusion to get less efficient. The Surface-to-volume ratio of a sphere decreases as the sphere gets bigger.
Explanation:
It stretched or compresses the sound waves it is producing if it is relatively moving away to getting closer respectively. This is called the <u>Doppler shift effect</u>..
This is why when a wailing ambulance approached you, the pitch of its wailing is high but when it passes you and moves away from you the pitch of the wailing lowers. Remember this is happening relative to your position.
