Answer:
It is Tube 3
Explanation:
This is because the beaker has a lower water potential then the others. Since the dialysis tube holds 100% water and the beaker holds 40% of water, water will move out of the bag to the beaker. Because of the low water potential on the beaker
Answer:
Mid-ocean ridges
Explanation:
This is when a divergent boundary causes two plates to move away from one another resulting in the seafloor spreading because of the magma pushing up between the two plates which happens at the Mid-ocean ridge location.

Muscle cells require more energy than most other cells in order to function. Therefore, muscle cells would be expected to have more ________ and ________ than most other animal cells.
A) Glycogen; Mitochondria B) Peroxisomes; Fat C) Mitochondria; Starch D) Ribosomes; Glycogen E) Glucose; Nuclei.
Answer:
A) Glycogen; Mitochondria
Explanation:
Glycogen is the stored form of glucose present in the animal cells. In human beings, glycogen is mainly present in muscle cells and liver cells. Breakdown of glycogen releases glucose which in turn can be fueled into cellular respiration to produce the energy required for the muscle contraction.
The aerobic phases of cellular respiration are Kreb's cycle and electron transport chain. Both of these occur in the mitochondria. Therefore, muscle cells are rich in glycogen storage and have plenty of mitochondria to ensure the supply of ATP required for their contraction. The contraction of muscles requires lots of ATP molecules as a source of energy.
