Which of the following statements about blood pH is true? A. Carbon dioxide is a buffer that helps the blood pH remain around 7.4.
B. Carbonic acid is a waste product that makes blood pH deviate from 7.4.
C. 7.4 is a neutral pH, and the whole body needs to remain neutral to maintain homeostasis.
D. At a pH too far from 7.4, enzymes in the blood will stop functioning properly.

D. At a pH too far from 7.4, enzymes in the blood will stop functioning properly.

Explanation:

The pH of blood is regulated 7.35 and 7.45. pH shows acid-base balance in the body and maintains a healthy balance of acidity and alkalinity.

Balance of acid-base provides optimum condition to enzymes to perform proper function. As, enzymes required optimum pH range for functioning properly, pH too far from 7.4 can denature the enzymes. Enzymes will lose its shape and will not function properly at high pH.

Hence, the correct option is D.

plz give me the characteristics.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
