Answer:

Buffers are the solution that is used to maintain the pH of the solution. It resists the change in the pH. Since, many of the chemical reactions are very specific to pH and temperature so it is very important to maintain the pH of the solution.

The bicarbonate ions and hydroxide ions serves as natural buffers in the blood. If the pH of the blood goes down below the normal then bicarbonate ions are released to maintain the pH of the blood.

If the p of the blood goes more than normal then the hydroxide ions acts as a buffer and maintains the pH of the blood.

Match the characteristics to the blood vessels.
oksian1 [2.3K]

Answer:

Artery : carries blood away from the heart, largest blood vessel in diameter  

Vein : carries blood to the heart, has a thin endothelial layer.

capillary : exchanges nutrients with tissues, single walled.

Explanation:

Arteries are blood vessels that transport blood away from the heart to the body. They are the largest blood vessels in the body and have thick elastic walls.  

Capillaries are blood vessels that carry blood away from body and exchange waste, nutrients, and oxygen with cells or tissues. Capillaries are smallest blood vessels and their walls contain only a single layer of tissues.

Veins are blood vessels that transport the blood from the body to the heart. Veins have less connective and smooth muscle tissue that make veins' walls thinner that walls of arteries.

Using the s-p timing method, epicenters can be located using seismograms from a minimum of ______ recording stations.
KATRIN_1 [288]

The SP timing method is a technique, which is useful for finding the epicenter of the earthquake. The Seismograph at a particular station shows the S and the P waves. The difference between the S and the P waves can be used to determine the distance, which waves have travelled in order to reach the seismic station.

The distance obtained is the distance of the epicenter from that seismic station, in order to determine the epicenter the circle is drawn in the map keeping the seismic center at the center. Same process is done by three or more seismic centers. The point, where the circle drawn by three or more seismic centers meet is considered as the epicenter.

Hence, the correct answer is Three.
