<span>Yes,
there are mammals that lay eggs instead of giving birth to a live young. These mammals
are called Monotremes. One best example to this is the platypus and echidnas.
Platypus, which is also known as the duck-billed platypus, is a semiaquatic
egg laying mammal. Echidnas on the other hand are also called as spiny eaters.
Echidna and platypus are only the surviving members of the Tachyglosside. And are
the sole extant egg laying mammal</span>

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.
