Okay lol whats your question
Answer:
it's a alarmed and angry
Explanation:
the reason why it's a is because she hissed " boy, what are you doing here?"
she was alarmed and angry.
A current-controlled, three-terminal semiconductor device used for the control and amplification of electronic circuitry is called transistor
A transistor is a semiconductor device that switches or amplifies electrical impulses. The transistor is one of the fundamental components of contemporary electronics. [1] It has at least three terminals for connecting to an electronic circuit and is made of semiconductor material. The current flowing through another pair of the transistor's terminals is controlled by the voltage or current provided to one set of those terminals. Because the regulated (output) power might be higher than the controlling (input) power, a transistor can amplify a signal. Although many more transistors are found embedded in integrated circuits, some are packaged individually.

It generally depends on the teacher you're working with. But to be on the safe side, I'd incorporate your first and last name, the date the assignment was finished on, which assignment it was, and your teachers name. Anything else like lesson number and school name can be left out, but you might want to annalyse it before forgetting, or adding it in.
The death of infants are referred to as infant mortality ( So you can say for example "Infant mortality is a big problem for some countries) and the number of such deaths per 1000 births is called the infant mortality rate.
The infant mortality rate is very high for example in Africa and in India
