Answer 1

Answer:

Hello....

Explanation:

a)There are four major types of nonrenewable resources: oil, natural gas, coal, and nuclear energy. Oil, natural gas, and coal are collectively called fossil fuels. Fossil fuels were formed within the Earth from dead plants and animals over millions of years—hence the name “fossil” fuels.

b)Amoebas, bacteria, and plankton are just some types of unicellular organisms. They are typically microscopic and cannot be seen with the naked eye.

c)Examples of desirable friction:

1)Due to Friction, it makes us possible to walk.

2)We can write on blackboard due to the friction of the chalk with the blackboard.

3)On account of friction, some chalk particles get stuck on the board and we see the writing clearly.

d)Examples of metals are aluminium, copper, iron, tin, gold, lead, silver, titanium, uranium, and zinc. Well-known alloys include bronze and steel.

e)Cell Organelles:

1)Nucleus

2)Ribosomes

3) Endoplasmic Reticulum

4)Golgi Apparatus

5)Chloroplasts

6) Mitochondria
