(1)
True, both the thin and thick filaments do not change length when the muscle contracts.
Hence, the statement is true.
(2)
True, the aerobic respiration that place in the mitochondria uses glucose and oxygen to make ATP.
Hence, the statement is true.
(3)
True, Schwann cells form and wraps myelin sheaths around the axons and increase the speed of action potentials.
Hence, the statement is true.
(4)
True, the neuron from inside is slightly negative relative to the outside of the cell.
Hence, the statement is true.
(5)
False, the lens of the eye is convex.
Hence, the statement is false.

All are true/false questions, as many as you can do will be appreciated! Will rate! Action potentials of a given neuron are generally of the same amplitude, but postsynaptic potentials can be of varying amplitudes. (t or f) The lipid bilayer is permeable to certain ions such as K+ and Cl-.
