Why is it that apple slices can be kept from browning by brushing them with lemon juice. infer what role lemon juice plays in this case?
Ascorbic acid from lemon juice act as a preservative; the reaction between polyphenol oxidase (an enzyme) with oxygen from air is stopped.
What substances plays a mojor role in generating the membrane potential of a neuron?
Well, for starters, membrane potential is a separation of charges across the membrane. So i think what you mean is "generating the action potential in a neuron". So in that case The substance that plays a major role in generating an action potential is Sodium (Na+). However, if you really mean membrane potential, there is only two substances associated with that and those are sodium (Na+) and potassium (K+).However, in truth, the generation of an action potential depends on the ligand and its receptor.
Where are the nerve cells located?
Nerve CellMany nerve cells are of the basic type illustrated above. Some kind of stimulus triggers an electric discharge of the cell which is analogous to the discharge of a capacitor. This produces an electrical pulse on the order of 50-70 millivolts called an action potential. The electrical impulse propagates down the fiber-like extension of the nerve cell (the axon). The speed of transmission depends upon the size of the fiber, but is on the order of tens of meters per second - not the speed of light transmission that occurs with electrical signals on wires. Once the signal reaches the axon terminal bundle, it may be transmitted to a neighboring nerve cell with the action of a chemical neurotransmitter.The dendrites serve as the stimulus receptors for the neuron, but they respond to a number of different types of stimuli. The neurons in the optic nerve respond to electrical stimuli sent by the cells of the retina. Other types of receptors respond to chemical neurotransmitters.The cell body contains the necessary structures for keeping the neuron functional. That includes the nucleus, mitochondria, and other organelles. Extending from the opposite side of the cell body is the long tubular extension called the axon. Surrounding the axon is the myelin sheath, which plays an important role in the rate of electrical transmission. At the terminal end of the axon is a branched structure with ends called synaptic knobs. From this structure chemical signals can be sent to neighboring neurons.
What type of force holds the electrons in there orbits?
It is the electromagnetic force, one of the four fundamental forces in nature, that holds electrons in orbit around an atomic nucleus. The electrons have a negative charge, and the protons in the nucleus have a positive charge. The opposite charges attract each other. The electromagnetic force also dictates how the electrons in orbits behave, too. Remember that electrons, because they have the same negative charge, don't like each other. They will form the electron cloud around an atomic nucleus, but they behave the way they do with respect to each other because of the electromagnetic force. Chemistry is a study in electromagnetics.

What are the rules of attraction for females?
The rules of attraction change from person to person, but all follow the same structure. For example, the sent that provokes attraction in one female may be more dominant in one person than another. It is the combination of all the other rules which make up how attracted a female will be to another person. Symmetry is important in attraction to face and body, Power and Status plays a big role in long term thinking, and age will have a more immediate effect on attraction.
How does the electrical force differ from gravity in its manifestation?
Electric force between electric charges where as the gravitational force is between the masses. Electric force is of two types both attractive and repulsive as like charges repel and unlike charges attract. But gravitational force is of only attractive. Electric force between electric charges. So the constant of proportionality has the electric permittivity property. But in case of gravitation, universal gravitation constant plays the equivalent role. It will be the same irrespective of the medium. In case of electric field, permittivity of the medium differ from each other. THe weakest force is the gravitational force where as the electric force would be comparativeley larger. Relatively moving electric field would bring magnetic field. But moving gravitational field does not produce any such field.

Macbeth is one of Shakespeare's longest plays?
THE OPPOSITE is true: it is one of the shortest (and it's the shortest of all the tragedies). The two plays that are shorter are both comedies: A Comedy Of Errors is the shortest and The Tempest is the next shortest. Macbeth is the third shortest of all the plays.
