You would expect an earthworm to have no exoskeleton because as you see it is very flexible and soft. Organisms with such have body parts that are divided and an earthworm do not have any visible parts on them also having an exoskeleton would not allow an organism to move like an earthworm does.
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.
Answer:
B. The cell cannot be a human
Explanation:
Humans have 23 pairs of chromosomes, or 46 individual chromosomes. Mutations in humans usually cause there to be a single extra chromosome, or a single missing chromosome. A mutation would not cause there to be 64. So, A cannot be true. Prokaryotic cells usually have one chromosome, not 64, so C cannot be true. D cannot be assumed as you cannot tell if there is uncontrolled cell growth. Therefore, the answer would be B.
Answer:
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation (such as after tree-felling in a woodland) and destructive events such as fires.
The answer is B. Natural selection will find a way to affect one, then that one will affect many others.
