A molecule of methane contains one atom of carbon and four atoms of hydrogen.
7. Which of these animals is NOT a herbivore?

Herbivores are those organisms which feed directly on plants. Carnivores eat meat by feeding on other animals. Frogs eat insects, therefore, it is a carnivore.
8. Which of these changes is a chemical change?

Answer: slaking of lime

A chemical change is a permanent irreversible change which cannot be changed by reversing the conditions and where new substances are formed. A physical change is a temporary reversible change which can be changed by reversing the conditions and where no new substances are formed. Once lime is slaked, it cannot be changed back to its original form by reversing the conditions, so it is a chemical change.

Karl Landsteiner discovered that if blood from different groups is mixed, the haemoglobin present in blood gets destroyed. He was given the Nobel Prize for Medicine for this.
