Answer:
The correct option is;
Action potentials travel the length of the axon
Explanation:
A dendrite are nerve cell projections that are used for receiving signals from other nerve cells
A neurotransmitter is the chemical, produced by the nerve cell to contain the message the nerve cell intends to transmits across a neural junction, to the cell for which the message is meant such as a muscle cell, gland cell, or other nerve cells
Therefore, the received message from the dendrite by the present neuron are transported using action action potential which is the means by which electrical signals are transported by a neuron through the length of the axon which is the projection of the nerve cell, known as the nerve fiber that conducts action potential which are electrical impulses to other destination by traveling the length of the of the axon to the location of the destination cell of the action potential
The most electronegative element is fluorine. <span> And since it is the most electronegative element the electrons tend to "hang out" more toward the fluorine atom when fluorine is covalently bonded to other atoms. Hope this answers the question. Have a nice day.</span>
Explanation:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
There isn t a 'middle' carbon because there is an even number of them
If the methyl group braches off the 3rd carbon the name is
hexa-3-methyl-3-ene
Answer: (3) Energy is absorbed as bonds are broken, and energy is released as bonds are formed.
Explanation:
1) The equation given is H₂(g) + Cl₂(g) → 2HCl(g) + energy
2) The energy is shown in the product side, so energy is a product of the reaction, so energy is release.
But this is just the net energy of the process. You need more insight to deal with the energy changes in the reaction.
3) Chemical bonds store energy; this stored energy is the potential chemical energy of the molecules.
When a chemical reaction occurs, the first stage is to brake bonds.
Braking chemical bonds requires energy to overcome the bond energy. Braking bonds always absorbs energy.
On the other hand, forming bonds always release energy.
The neat energy of the reaction is the difference between the energy needed to break bonds and the energy released when new bonds form.
So, regardless the fact that, in the chemical equation that represents the reaction a net energy release is shown, you know that energy is absorbed as bonds are broken, and energy is released as bonds are formed (option 3).
