Answer: 5.6 Mev

Explanation: Binding energy is calculated by using the formula,

bonding energy = mass defect x 931 Mev

mass defect is given as 0.042 amu.

So, binding energy = 0.042 x 931 Mev = 39.012 Mev

Sum of protons and neutrons is known as number of nucleons. Li has 3 protons and 4 neutrons.

So, number of nucleons = 3+4 = 7

Binding energy per nucleon = \frac{39.102Mev}{7}

binding energy per nucleon = 5.6 Mev

So, the binding energy per nucleon for Li is 5.6 Mev where Mev stands mega electron volt.

Which scenario best exemplifies the way a signal is passed down an axon coated with myelin sheath?
goblinko [34]

Runners sprinting short distances in a relay race and handing off a baton scenario best exemplify the way a signal is passed down an axon coated with a myelin sheath.

Axons are long extensions of neurons (or nerve cells) involved in the transmission of nerve impulses away from the cell body. Each nerve cell has an axon that is over a foot long. A nerve cell communicates with another nerve cell by transmitting signals from the branches at the ends of the axon.

Each neuron in the brain has long cables that meander from the body of the cell. These cables, several times thinner than human hair, are called axons and are where electrical impulses leave neurons and are received by other neurons.

There are so many routes by which water can move through the various stages in the water cycle.

<h3>What is the water cycle?</h3>

The water cycle has to do with the route of movement of water in the enviroment. We have to note that there are so many routes by which water can move through the various stages in the water cycle.

The sun supplies the energy that drives the water cycle. This is seen in the fact that the supply of energy from the sun is required for evaporation to take place.
