Topic: Skeletal Muscle a. What is a motor unit?

b. For a skeletal muscle fiber to contract, it must receive a stimulus from its motor neuron. This occurs within the neuromuscular junction (NMJ).

Discuss the ENTIRE mechanism of skeletal muscle fiber contraction at the NMJ: beginning with the mechanism for release of neurotransmitter from the pre-synaptic motor neuron and continuing through the entire mechanism leading to the contraction of the skeletal muscle fiber.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )

wha is what i will use to get my free points

do yall know the answer?

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
