Valves are structures that allow for one-way blood flow through the heart.
Volcanic eruptions cause magma to rise through cracks or weaknesses in the Earth's crust and when the pressure is released magma explodes causing a volcanic explosion. Hope this helps! :)
I'm pretty sure it is B neutrons to protons
Answer:
At what rate do the mitochondria of the cell need to convert glucose to usable
energy molecules to meet the high energy needs of the cell?
Explanation:
Organelles are organ-like structures found in cells. The are responsible for the specific actions carried out by each cell. Each organelle has its own specific role to play. However, missing or damaged organelles can have effects on the cells.
Mitochondria are organelles found in cells of all eukaryotic living organisms e.g animal, plants as they are responsible for the synthesis of energy in form of ATP. Since the cells being investigated in this question is a MUSCLE CELL, which is only found in animals, then an appropriate organelle must be investigated.
The appropriate to be asked to know if muscles cells are functioning properly is: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?.
Note that, other options are incorrect because muscle cells do not have chloroplast and cell wall, while ribosomes are not site for glucose production.
