Answer:
The correct answer is option A. "The rate of diffusion would be faster for the right cylinder".
Explanation:
The rate of diffusion is defined as the amount of molecules that are exchanged from a body to another. The rate of diffusion is directly proportional to the ratio of surface area to volume , where the higher the ratio of surface area to volume the higher the rate of diffusion. In this case, a sphere have a ratio of surface area to volume equal to 0.3 m, and a right circular cylinder have a ratio of surface area to volume equal to 2.1 m. Since the right cylinder have a higher ratio of surface area to volume, the rate of diffusion would be faster for the right cylinder.
The correct answer is option B. The buffer system that is important to be present in the blood is the carbonic-bicarbonate buffer. It is essential because it is coupled with the respiratory system. It is the production of carbon dioxide that couple with this system.
Answer:

Jupiter is mostly made of gas.
Just took the test!
Answer:
Hydrogen Bonds
Explanation:
In the polymerase chain reaction (PCR) the temperature rises to 90 ° C - 95 ° C, to break the hydrogen bonds, which are the types of bonds responsible for pairing the two strands of DNA, this process is known as denaturation of DNA.
The DNA is extremely stable, due to a large number of bonds (hydrogen bonds) that form between the two strands. If the temperature decreases, these bonds will begin to recompose, until the DNA returns to its original state
The question is not asked very well, you man mean that this individual is the patron.
You should call 911 (or any emergency service in other countries) if the individual loses consciousness because it is a sign of a severe dehydration.
While waiting for the ambulance to arrive, you should keep the individual in a cool place with shadow, and give him water to rehydrate.
To complete your sentence: An individual who has been in the hot sun all day complains of weakness and nausea. they are sweating a lot. you have someone call 911 right away if the patron refuses water.
