Answer:
a. In the presence of 2,4 dinitrophenol, which is soluble through the lipid membranes, the H+ gets an another route to pass through the membrane. It hampers the proton gradient potential without any generation of ATP. The gradient that was being utilized for the generation of energy is now just lost in the form of heat.
b. With the reduction in the generation of energy, the cells get devoid of ATP, and drive the electron transport chain intensely so that the collapsing proton gradient gets re-established. However, it prevents the ATP synthase by providing a different path to the proton ions and thus diminishing the H+ concentration gradient.
Answer:
<u>prokaryotes</u>
Explanation:
The first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as <u><em>prokaryotes</em></u>, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.

An object in motion needs less force
to continue moving because the inertia or the resistance to change in motion
was already overcome and the sliding friction that opposes a moving object is
also lesser. Therefore, <span>it is easier to
move an object at constant velocity as you only need to overcome the resisting
forces of the object.</span>
