In both cases of where the electron transport chain is present in both processes of energy conservation, cellular respiration and photosynthesis, the ion that forms the concentration gradients as a result would be the Hydrogen ion concentration gradient.
Answer:
True.
Explanation:
The unequal distribution of ions inside and outside of the cell makes the membrane potential of the cell. The potential is important for the conduction of the impulse and generation of the action potential.
The resting membrane potential of the nerve impulse is maintained by the presence of large potassium ions inside the cell. The resting membrane potential is -70mV. The depolarization of the membrane occurs due to influx of the sodium ions.
Thus, the answer is true.
Lymphatic
system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.
Answer: A. Only the strongest animals survive.
The theory of natural selection - the survival of the fittest suggests differential survival and reproduction of the organisms. This means the organisms that have better phenotypic advantage over the others likely to survive and reproduce in the adverse environment. Such phenotypic traits will be passed from the parents to the offspring and will promote the evolution of the species.
On the basis of the above description, the only the strongest animals will survive is the correct option.
Answer:
C. Membrane-bound Nucleus
Explanation:
There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead.
