A beaker is better for heating compared to a test tube because it does not break up easily.

You say sorry to your parents then try to get better grade in Math test next time. Study harder.
a streak test is a test wheree you rub a mineral across a streak plate to see the color of its streak, which is a better indentifying factor of the mineral than the external color. A scratch test is when you scratch a mineral to find out its hardness on the Mohs Scale of Hardness. This is also another useful identifying factor
Well it is bad to cheat on any test. It is against the rules and morally wrong. It is also unfair to those who study and try hard to do their best without cheating. You are better off doing your best, even if you do poorly, and not cheating. You will sleep better and learn more too. Try it!
Do extra credit, or if possible, ask to rewrite a test or assignment to get a better grade for your report card.
It depends on the volume of the beaker and the test tube. Although throughout my scientific experience, beakers are larger than test tubes.

1. Never heat alcohol directly on naked flame 2. you should take a beaker with boiled water in it and then place the alcohol with the test tube in it 3. you should wear goggles while heating alcohol. 4. never smell the alcohol directly after heating

If you place the thermometer so it touches the sides of the test tube, you are measuring the temperature of the test tube, not the substance in the test tube. So, in order to get an accurate reading of the substance, do not touch the sides of the test tube with the thermometer.
Not usually. A beaker is used for measurement.

explain why the iodine test gave such results upon prolonged heating
Bigger, fatter test tubes are usually called boiling tubes.
