Only eukaryotic cells contain membrane bound organelles (such as a nucleus). Prokaryotic cells do not. Therefore, the answer is A.
5. The answer is D. Non-renewable resources lay be cheap, but they release harmful carbon dioxide, which pollutes the environment. And eventually, they will run out. They are, as the name suggests, non-renewable.
6. The answer is A. Renewable resources are harder and more expensive to harvest, but they are unlimited and cause little to no harm to the environment, depending what resource you are using.
7. The answer is A. Particular renewable resources ( i.e sunlight or geothermal energy) are unreliable and can only be found in the right places under the right conditions (i.e on a sunny day or a geyser). They're also more expensive since they're harder to access/convert into electricity.
8. The correct answers are D and E.
Technology helps us predict future problems and solve them before they even happen, and things like solar panels and dams help us use alternative energy, which is much better for the environment than things like coal or oil.
9. The correct answers are A and D. Biodiesel is made from various oils and animal fats (unwanted waste), and it is renewable.
10. The correct answer is A. Biodiesel is more expensive to make than regular diesel, and more facilities would have to be built.
Good luck on your assignment!
The membrane is composed of phospholipid bilayer arranged back to back.
The plasma membrains selectively with cholesterol molecules and proteins
Answer: True
Explanation:
The role of NADH and FADH2 is to donate electrons to the electron transport chain. They both donate electrons by providing an hydrogen molecule to the oxygen molecule to produce water during the electron transport chain. NADH is a product of both the glycolysis and Kreb cycles.(TCA) FADH2 is only produced in Krebs cycle.
