Answer:
Explanation:
The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.
This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.
So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:
The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.
Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>
Answer:
Chimpanzee
Explanation:
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
Enzymes are biological molecules that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. The vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.
Answer:
The answer is C. BPG aids oxygen delivery to tissues by increasing the affinity of myoglobin for oxygen
Explanation:
The 2,3-bisphosphoglycerate (BPG) which can also be referred to as the 2,3 - di phosphoglycerate , is being produced by the red cells and has the ability to deoxygenate hemoglobin. This is because , his accumulation results to a decrease in the affinity for oxygen, this means that , it will convert hemoglobin to a low oxygen affinity state.
In this case, comparing the options given, it will be concluded that, 2,3 -biphosphoglycerate {BPG} does not aids the delivery of oxygen to tissues, but decreases the affinity of oxygen, which deoxygenate hemoglobin, and causes the concentration of the carbon dioxide to increase.
