During the riding of the steep mountain, the body needs more energy because going up consume more energy and oxygen due to additional effect of gravity on your momentum.
<h3>What is the effect of cycling?</h3>
Cycling is a good exercise as swimming, while cycling, happy hormones are released like dopamine and serotonin.
The primary forces that work while cycling are gravity, friction, rolling resistance, and air resistance.
Thus, During the riding of the steep mountain, the bod needs more energy because going up consume more energy and oxygen due to additional effect of gravity on your momentum.

Answer:
D
Explanation:
In a Helium (He) atom, the atomic structure of the atom has 2 protons, 2 electrons and 2 neutrons. For an element X to be a Helium (He) atom, it must possess 2 protons. The number of neutrons present will determine its stability either if its probably radioactive or a natural occurring inert gas.
In option 1,
We have H-2. The symbol "H" is used to denote the element hydrogen in the periodic table and hydrogen has only 1 protons and 1 neutron making its mass number 2.
Option 2,
He -2 : here in this option, we have a helium atom, but with mass number of 2 only. Judging from the formula of mass number = protons + neutrons, we already have proton as 2, hence the number of neutrons there is zero (0)
Option 3,
He - 3 : just like in option 2, the only difference here is that the mass number is 3 hence making the number of neutrons just 1.
Option 4,
He - 4 : This option met the requirements of having 2 protons and 2 neutrons making a total of 4 which corresponds to the mass number.
