Which argument correctly compares viruses and bacteria?

A

Viruses and bacteria are both living organisms because they are both capable of causing disease.

B

Viruses and bacteria are both living organisms because they both contain DNA and are capable of reproducing.

C

Viruses are living organisms because they contain DNA and are capable of reproducing inside of a host cell. Bacteria are not living organisms because they are made up of cells and are capable of causing disease.

D

Viruses are not living organisms because they are not made up of cells and cannot reproduce outside of a host cell. Bacteria are living organisms because they are made up of cells and do not require a host cell to reproduce.

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
