A scientist wants to examine a genetic disease in humans. The scientist hypothesizes that the disease can be treated by using gene therapy. Humans take a long time to reproduce and develop, so the scientist will have to give up on testing the hypothesis.
test the hypothesis for a very long time.
develop new methods to test the hypothesis.
find a way to make humans reproduce faster.

Explain how sequences of amino acids in proteins can be used to reveal relationships among organisms.

Is dna the same in every cell in the human body explain your answer

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).
