Answer:
When the bladder is completely deflated, the fish has minimum volume and sinks to the ocean floor
Answer:
Both are anaerobic processes that break down glucose to make ATP and recycle NAD+ to glycolysis. Lactic acid fermentation produces lactic acid, alcoholic fermentation produces alcohol and carbon dioxide.
Explanation:
The answer is B. When diatoms die and fall off the ocean column to the ocean floor, they become part of sediments over time. When they are mined and exposed, they turn to a diatomite. Diatomaceous earth is significant as a pest repellant because of its hygroscopic property and has very abrasive particle hence it absorbs the water-protective fats and oils from the outermost layer of insects.
Answer:
The correct answer is C. The enzyme that ensures there is an equal distribution of newly synthesized phospholipids across the membrane is the scramblase.
Explanation:
Scramblases are proteins used to move phospholipids from one monolayer to another of the lipid bilayer inside the plasma membrane of a cell. This protein, unlike flippase, is not selective with respect to lipids but "reverses" them on the other side of the membrane in a random and non-specific manner. It therefore causes the phospholipids not to be added only on one side when the membrane is formed or expanded, but also on the opposite side in contact with the extracellular environment.
