The body's nervous system is made up of the brain, the spinal cord, the retina ,and many other nerves. the circulatory system is made up of the heart, arteries, veins, and capillaries. the nervous system tells the heart when to beat, and the circulatory system supplies nerve cells with blood. which of the following best describes the relationship between the nervous system and the circulatory system?

The circulatory system and the nervous system depend on each other.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
