Structurally, DNA and RNA are nearly identical. As mentioned earlier, however, there are three fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine.
Explanation:
Simple Diffusion across the Cell (Plasma) Membrane The structure of the lipid bilayer allows only small, non-polar substances such as oxygen and carbon dioxide to pass through the cell membrane, down their concentration gradient, by simple diffusion.
Answer:
D

Fermentation produces a net gain of 2 ATPs
Aerobic respiration produces a net gain of 32 ATPs
Answer: robotic structures will truly give a sense of invincibility to people. Might even perform lab tests without the intervention of humans.There are good reasons for engineers to develop medical robots for use in healthcare. Unlike human beings, robots are tireless, and their "hands" never shake. They can perform precise movements even beyond the human range of motion and be present with patients for as long as necessary. Plus, they can automate lower-level or repetitive tasks and leave the high-level work to humans.
