In facilitated diffusion, substances move into or out of cells down their concentration gradient through protein channels in the cell membrane. Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient.
Answer:
B. Sea stars are the prey of seagulls
Explanation:
Seagulls eat sea stars, meaning that sea stars are their prey (the organism that is eaten).
Predator: an organism that eats (preys on) another organism
Prey: an organism that is eaten by another organism (creatures can be both predator and prey. For example, a rabbit is a predator to grass, while they are prey to foxes)
Host: An organism that is fed on by a parasite. Think of a dog with a tick. The dog is the host, the tick is the parasite.
Incorrect answers (and why):
A. Sea stars do not eat seagulls
C. If a sea star was a predator to a seagull, that would mean that they eat seagulls. They do not.
D. A host is an organism that a parasite preys on. Not only are sea stars not parasites, but they definitely do not prey on seagulls.
I hope this helps! :)
Answer;
-Glycolysis
Glycolysis is common to both fermentation and cellular respiration.
Explanation;
Glycolysis is a universal process that is common to both cellular respiration and fermentation or anaerobic respiration.
- Fermentation and cellular respiration are similar in that they both begin with a series of reactions known as glycolysis, which breaks glucose molecules into smaller pyruvate molecules. They are also similar in that during both processes, ATP is produced for the cell to use.
-Fermentation and cellular respiration are different because, fermentation does not require oxygen but cellular respiration requires the presence of oxygen, and also water molecules are not produced during fermentation but are produced during cellular respiration.
