If your medulla oblongata becomes damaged, it can lead to respiratory failure, paralysis, or loss of sensation
<h2>Answer:</h2>
<u>The correct choice is </u><u>D. thermal energy</u>
<h2>Explanation:</h2>
According to the zeroth law of thermodynamics, if two thermodynamic systems are each in thermal equilibrium with a third one, then they are in thermal equilibrium with each other. Accordingly, thermal equilibrium between systems is a transitive relation.Hence option D is the right answer
As per the question the first atom has 1 valence electron.
The second atom has 7 valence electrons.
The two atoms come closer and combined to form a substance.
Atoms having one valence electrons will be considered as electropositive and the atoms having seven valence electrons are considered as electronegative .
As per the octet role,every atom tends to possess eight electrons in their valence shells to satisfy the inert gas configuration to be stable.
Here the atoms having one valence electrons will lose one atom and atoms having seven electrons will accept this electron .In this way both the atoms will satisfy inert gas configuration. The atom which will lose electrons tends to form cation and the atom which will accept electrons tends to form anion.So there is the chance of formation of ionic bond.
The electronegative atom can not emit seven electrons as it will require more ionization energy.The atom having one atom in its valence shell can not accept one electron from the other atom as by doing so they will lose their stability.
There will be no sharing of electrons here.It is because the atoms having one atom in their valence shell has low ionization energy and atoms having seven electrons in their valence shells have high electron affinity.Here ionic bond is favorable not covalent bond.
Hence the option C is right.

The minimum input force she'll need to lift the ball is 35 N.
Explanation:
Mechanical advantage of a single pulley is 1. As, she applies 70 N of force to lift the bowling ball, so the output force(weight of the ball) is also 70 N.
Now, adding another pulley gives a mechanical advantage of 2. We have,
M.A = (Output Force)/(Input Force)
Substituting the values we get,
= 35 N
Input force equals to 35 N needs to be applied.
