Answer:
b. the use of DNA as the information storage molecule
Explanation:
Prokaryotic cells are the ones that lack the membrane-bound organelles and well-defined nucleus. Eukaryotic cells have the nucleus and other membrane-bound organelles. Most of the prokaryotic cells are smaller in size as compared to eukaryotic cells. Despite these differences, both prokaryotic and eukaryotic cells have DNA as their genetic material. DNA serves to store genetic information in both types of cells.
Answer:
Tế bào được coi là đơn vị cơ bản của sự sống một phần vì chúng có dạng gói rời rạc và dễ nhận biết. Đó là bởi vì tất cả các tế bào được bao quanh bởi một cấu trúc gọi là màng tế bào - giống như những bức tường của ngôi nhà, đóng vai trò như một ranh giới rõ ràng giữa môi trường bên trong và bên ngoài tế bào.
Explanation:
What??? Do you have any more info on this question?
Answer:
1. Oxygen is an effective final electron acceptor in cellular respiration because of its high electronegativity.
2. Organisms that use it as a final electron acceptor can produce more usable energy than organisms that do not use oxygen, but only if it is available.
3. With more available energy, aerobic organisms can grow larger and move faster.
Explanation:
1. Cellular respiration is an aerobic pathway because oxygen is an electron acceptor. This process produces 38 molecules of ATP per glucose. The atomic elements that are positioned at the right of the periodic table have high electronegativities because they tend to be electron acceptors.
2. The efficiency of energy production of aerobic respiration is much higher compared to the anaerobic respiration because this metabolic pathway (aerobic respiration) can produce 38 molecules of ATPs per glucose molecule, while anaerobic respiration produces only 2 ATPs by glucose.
3. A higher amount of available energy improves the metabolic profile of the organisms with aerobic respiration.
