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>

"<span>b. the liver is able to manufacture some amino acids from others."
The liver has the capability to transform some amino acids into others (called non-essential because they can be produced by the body and there is no need to get them from food). This is done by transamination. Transamination is the process of transferring an amino group from one molecule to another without forming ammonia thanks to enzymes that are called transaminases and preform such transfer.</span><span>

In McMillen and Austin’s research (1971), participants who had lied were more likely to volunteer a large amount of time.
Explanation:
The research work conducted by Mcmillen and Austin in the year 1971, included college students as participants of the research. In this process they are asked to perform a small test of intelligence. One portion of them was asked to cheat and lie and the rest were left not to cheat.
After finishing the test, the participants were asked to help the administrator to conduct the next round of test for other slot of participants. It was seen that the students who did not lie or cheat, helped them in their work for about 2 minutes. But students, who did lie, stayed and helped for 53 minutes.
