Task 2.

(a)While you read find answers to these questions: What is the most common element in the solar system? In the Earth’s atmosphere? In your body?



(b) After reading the text match the words on the left with their definitions on the right.

	bicarbonate		a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26
	chromosome		a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
	experiment		a part, share, or number considered in comparative relation to a whole.
	gene		a salt containing the anion HCO3
	iron		a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
	molecule		a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
	nitrogen		a unit of hereditary information that occupies a fixed position (locus) on a chromosome
	nucleus		an instrument for weighing, originally a simple balance ( a pair of scales ) but now usually a device with an electronic or other internal weighing mechanism.
	organelles		any of a number of organized or specialized structures within a living cell.
	phosphorus		something done, felt, or thought in response to a situation or event.
	proportion		the central and most important part of an object, movement, or group, forming the basis for its activity and growth.
	reaction		the chemical element of atomic number 15, a poisonous, combustible non-metal which exists in two common allotropic forms
	scales		the chemical element of atomic number 7, a colourless, odourless unreactive gas that forms about 78 per cent of the earth's atmosphere.
	solar system		the collection of eight planets and their moons in orbit round the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets.

(c) Now put the words from the (b)task into these sentences.

Example: You use scales to weigh things.

1. A –––––––––––––––– is a part of a –––––––––––––––– which your cells can “read” to make proteins.

2. When you add sodium –––––––––––––––– to vinegar, you can see it –––––––––––––––– .

3. The –––––––––––––––– of –––––––––––––––– atoms in the human body is 0.22%.

4. You always follow the same model when you –––––––––––––––– an –––––––––––––––– .

5. I n a cell’s cytoplasm, there is a –––––––––––––– and several –––––––––––––––– .

6. A –––––––––––––––– is very small, but the –––––––––––––––– is very large.

7. –––––––––––––––– is a common metal, and –––––––––––––––– is a common gas.

8. If you put an acid together with a base, there is a chemical –––––––––––––––– .

(d) Match the English words to their definitions.
