I believe that the answer is A.
Oxygen moves across the membrane from the place where it's higher in concentration to the place with lower O₂ concentration through a process called diffusion.
The answer is B (horsetails). Hope this helps!
Vacuole can occupy up to 90% of the cell volume and can exert turgor pressure against the cell membrane when it acquires water.
In biology, a vacuole is a membrane-bound space found in the cytoplasm of a plant cell.
These are large size compartments that can occupy up to 90% volume of water.
In fully grown plants, vacuoles play a very significant role as they help out in plant growth, storing water, disposing of waste materials, and protecting cells against external barriers.
In sum, vacuoles are generally small in size but important cell organelles that are present in bacteria, fungi, and protozoa.

Answer:Although VO2 max is a good marker of fitness, it does present some downfalls. You can't really get an accurate measure .
Explanation:So, one way to determine your max VO2 pace is to warm up, then run for 8 minutes at the maximum intensity level you can sustain for 8 minutes. If, for simplicity's sake, you ran one mile, then your VO2 max training pace is 8 minutes/mile.
