Answer:
False
Explanation:
Not all molecules are compounds, since some molecules, such as oxygen gas (above image of molecule of-O2) or ozone (O3), consist only of one element or type of atom. Water is also a molecule because it is made from atoms that have been chemically combined.

Answer:
c. To facilitate a reaction of one substrate to form two products without the use of water
Explanation:
A lyase is an enzyme that catalyzes - accelerates the chemical reaction - in which a substrate is broken into two molecules. The reaction does not involve hydrolysis or oxidation, so the water molecule is not included in the chemical reaction. Thus, the enzyme facilitates the reaction in which a molecule (substrate) is decomposed into two molecules with the elimination of chemical bonds.

<u>Answer:</u> The correct answer is Option D.
<u>Explanation:</u>
We are given that car travels with a speed of 80 km/hr and we need to convert it into hm/s.
For that we use the conversions:
1 kilometer = 10 hectometer
And, 1 hour = 3600 seconds
To convert the quantity into hm/s, we multiply the numerator which is 80 by 10 to convert the whole quantity into hm/hr and now, to convert the result into hm/s finally, we divide the result by 3600.
Hence, the correct answer is option D.
