We do quite often have mutt birds. (the correct name for such a mutt is a hybrid. <span>They are way more common than most people think, but unless you are a birdwatcher you probably wouldn’t even spot them. People often see an odd looking birds and simply think it’s a type they haven’t seen before, when in fact it is a hybrid of two well-known species.
Having said that, for birds to hybridized they have to be fairly closely related to start with. Robins and blue jays are no more closely related than humans are to baboons. You wouldn’t expect a human and a baboon to be able to mate and produce babies would you? So no, robins and blue jays can’t interbreed.
However there are many different species of animal that CAN interbreed and produce offspring. But the different species need to be fairly closely related, far more closely than human and baboon… or a blue jay and a robin.
For example we can interbreed horses and donkeys to produce baby mules, and we can breed cattle and buffalo, or camels and llamas. And the same is true of birds. While blue jays can’t be bred with robins in the wild we quite frequently find mutt birds.

Ducks are particularly noted for forming wild mutts and many if not all north American mallards for example are of mixed species ancestry.</span>

Answer:
Yes.
Explanation:
Yes, the structures and functions of the central nervous system work to help prevent injuries with the help of bone. The main line of defense of central nervous system is the bones of the skull and spinal column, which create a hard physical barrier to injury. If these line of defense are not present for central nervous system so it has more chances to get injury so we can say that the structures and functions of the nervous system helps to prevent injuries.
Answer:
Release of electrons from reducing powers to O2 via four protein complexes allows release of small amount of energy at each step and makes the process energy efficient.
Explanation:
If NADH and FADH2 would reduce O2 directly, a large amount of energy would have been released in a single step. On the other hand, oxidation of these reducing powers through a series of electron carrier release a small amount of energy at each step which in turn is temporarily stored in form of proton motive force across the inner mitochondrial membrane.
Transfer of a pair of the electron to O2 pumps four protons by complex I, four by complex III and two by complex IV. The resultant proton motive force effectively stores the energy of electron transfer. This energy is then used to drive ATP synthesis.
