When Amanda poured some of the liquid in a test tube, she noticed that the edges of the water curved upward, which is an example of adhesion.
When Pol filled another test tube to the top, the liquid formed a low dome, which is evidence of cohesion.
When Amanda added table salt to the first test tube and shook it, she noted that the liquid had dissolved the solute.
All of these observations indicated the presence of covalent bonds.
Pol determined that the pH of the sample is 7, which shows the sample is neutral.
Based on all of the evidence Amanda and Pol gathered, the unknown liquid is water.
A. An increase in the amount of acid rain can change the pH of soil in an ecosystem.
Basically it helps with reproduction in flowers by carrying a male gamete from one flower to another and then fertilizing in cross-pollination with the pistil of another flower.
hope this helps :)
Answer: E.) The high temperatures denature (destroy) most of the
fish's enzymes, but the bacteria have enzymes adapted to
these temperatures.
Answer:
Explanation:
Extreme temperature can damage the enzymes and they will no longer remain active. This can causes the denaturation of enzymes. Certain species of bacteria are thermophiles, that is bacterial species can live in the environment, which exhibit temperature higher than normal.
The fish enzymes may not be able to sustain in the high temperature and the fish will die but if the bacteria belong to the thermophile strain then the bacteria will hey adapted to the high temperatures of hot spring.
