Answer:
70% solution is more effective
Explanation:
The 70% solution is more effective at inhibiting microbial growth than the 100% solution of the ethyl alcohol.
This is because the pure ethyl alcohol coagulates the protein that is in contact with it.
Also, pure alcohol will tend to evaporate faster than the 70% solution of the ethyl alcohol and it will not be that much effective.
With increase in altitude atm pressure decreases... :)
Answer:
Hypotheis:
<em>If high amounts of product in the samples, '+++' , correlates with optimal temperatures and pH for enzyme activity, then...</em>
- <u>A- Pepsin</u>
- <u>B- Amylase </u>
- <u> C- thermophilic enzyme</u>
Explanation:
Enzymes are specialized proteins that function as biological catalysts- <u>they speed up chemical reactions.</u> As proteins, these are susceptible to changes in temperature and pH- they function best at optimal values for both conditions, but can be denatured, rendering them inactive at relative extremes.
Each enzyme provided has its own optimal temperature and pH values.
- Thermophilic enzymes are usually found in regions characterized by high temperatures. They show high thermostability, and do not become denatured at high temperatures- they thrive, and do not function well at lower temperatures.
- Amylase is a hydrolase digestive enzyme found in the mouth, that acts on polysaccharides like starch to break 1,4 glycosidic bonds between glucose molecules. It works best at a physiological (neutral) pH and temperatures (around 37°)
- Pepsin, another digestive enzyme, is a peptidase that breaks down proteins into peptide molecules. It is found in the stomach lining, where the pH is typically low i.e. acidic due to the hydrochloric acid in digestive juices.
Thus from the table A- pepsin, B- Amylase and C- thermophilic enzyme can be hypothesized.
Answer:
Estimated Guess so D because if there are more then 10 rabbits you do not want to count every single one. So you would look at how many five are and see how many groups look like about 5 and then guess from there. So an estimated guess would quickly and easily get you a decent amount close to counting them.
Hows that for an answer.
Choice "C" In an Endothermic Reaction, a reactant is taking energy (in this case sunlight).
I hope this helped you!
Brainliest answer is always appreciated!
