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: 4
Explanation:
Fungi(mushrooms) are heterotrophs and they cannot fix nitrogen from the atmosphere and they must obtain it from their environment. They are using complex organic compounds as a source of carbon.
Most plants can fix carbon which are 1. Grass 2. Maple trees 3. Algae and hat are why they are incorrect answers because from this question only 4. mushrooms can fix carbon.
The area of the frontal lobe that is devoted to the production of fluent speech is the Broca's area. It contains neurons that is involved in speech production and language comprehension. It is classified into two parts namely the pars triangularis and the pars opercularis.
“Two species of crickets, Gryllus rubens and
Gryllus texensis, have different courtship songs which can be identified only
by the opposite sex of their own species” is an example of behavioral isolation.
Behavioral
isolation is an
important evolutionary mechanism that helps members of the same species
identify each other as proper mates.
The correct answer between all
the choices given is the third choice or letter C. I am hoping that this answer
has satisfied your query and it will be able to help you in your endeavor, and
if you would like, feel free to ask another question.
Answer:
Obstructive shock.
Explanation:
Obstructive shock may be defined as the shock that are associated with the physical obstruction of the vessels of the heart. The cardiac tamponade and Pulmonary embolism are included under obstructive shock.
Thrombosis is the blood clot formation in the blood vessels. This has caused the pulmonary embolsim. This is referred as obstructive shock as the heart vessel has been damaged in this case and also shows the cardiogenic shock in the patient.
Thus, the correct answer is obstructive shock.
