Answer:
The correct answer is A) Biochemical test
Explanation:
In microbiology biochemical test is used to examine the metabolic activities performed by bacteria to identify that microorganism. So in biochemical test enzymatic reaction of cell is usually investigated because there is difference in enzymatic activity of different species of bacteria.
For example, catalase test that is used to differentiate between catalase-positive and catalase-negative bacteria is an example of biochemical test. Catalase-positive bacteria have the catalase enzyme that breaks hydrogen peroxide into water and oxygen which is confirmed by bubbles that appear on glass slide.
Catalase negative bacteria do not form bubbles when they are put in hydrogen peroxide which shows that they lack catalase enzyme. So the right answer is A.
Options
A. Yes, because all enzymes and electron carriers are functional
B. No, because with a leaky membrane, the proton gradient cannot be maintained
C. No, because leaky membranes inhibit glycolysis
D. No, because leaky membranes do not allow NADH and FADH2 to donate their electrons to the electron transport chain
Answer:
B. No, because with a leaky membrane, the proton gradient cannot be maintained
Explanation:
The proton motive force (PMF) provides the needed pump to generate electrochemical gradients of proton needed for continue influx into the matix of the mitochondria. The proton Influx generates the energy needed by protein ATPase Synthase for synthesis of ATPs by adding inorganic phosphate to ADP to give ATP.
ADP + Pi -----------→ ATP.
If the mitochondria;l intramembrane leaks, then the PMF can not be sustained, therefore electtrochermical gradient which supplies the energy for ATP synthase for ATP synthesis will not be available. Therefore ATP synthesis stops.
The correct answer is (C) competition which determines the succession of an animal in the ecosystem.
<h3>
What factors influence when an animal species enters a successional ecosystem?</h3>
Interaction and competition among species in a certain environment is a biotic element of ecological primary succession. When succession begins and the first species, known as pioneer species, alter the environmental structure, new species that are more tolerant of the new conditions move in.
These communities gradually replace one another until a "climax community"—such as a mature forest—is attained or a disturbance, such as a fire, occurs.

Answer:
The answer is A.
Explanation:
To test if the selenium from the mine has an effect on the fish living in the lake which i assume is close to the mine, testing the tissue of the fish from that lake and comparing it to the selenium levels of the fish from a nearby lake would be a testable hypothesis because there is a comparable aspect and there should be a difference in the numbers between the fish from the two lakes because of their distance to the mine.
I hope this answer helps.
