The answer is A. Organisms compete for limited resources. A is wrong because it has nothing to do with reproduction which is natural selection.
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:
DNA is present as genetic material in all the living organism except some virus. DNA structure follows the Chargaff's rule in which states that the ratio of pyrimidines to purines is equal to 1.
So, amount of adenine will be equal to thymine. If adenine is 30% then thymine is also 30%. Total amount of DNA is 100%. Cytosine and thymine are also equal in the DNA molecule. The total amount of cytosine and guanine is 40%. The amount of cytosine is 20% and the amount of guanine is also 20%.
Thus, thymine is 30%, cytosine is 20% and guanine is 20%.
