Answer:
Four.
Explanation:
Prophase -> Metaphase -> Anaphase -> Telophase.
Answer:
C
Explanation:
Abundant evidence supports the major contentions of the seafloor-spreading theory. First, samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge.
Answer: D. The DNA sequences for the cytochrome c genes in chimpanzees and spider monkeys are over 90% identical.
Cytochrome c gene encodes for a protein that is very common among primates. This gene does not have undergone much changes during the process of evolution. Cytochrome c is a respiratory pigment found in the mitochondria of eukaryotes.
Answer:
a. Chemiosmosis requires the formation of an electron gradient.
b. In aerobic eukaryotes, chemiosmosis leads to the production of water and up to 34 ATP.
c. In eukaryotes, chemiosmosis requires that protons diffuse through ATP synthase in the inner mitochondrial membrane.
Explanation:
Chemiosmosis theory has been proposed for understanding the procedure for the production of ATP in eukaryotic organisms. In the process of chemiosmosis the movement of ions takes place across the semi-permeable membrane according to the concentration gradient. In the whole procedure the electrons move through various complexes and electron acceptors and finally reach to the final electron acceptor, the Oxygen. Due to the movement of electrons the energy is released which is used to pump the protons across the membrane.
Answer:
