Having put some hours studying biology, chemistry and physics, i have come to discover some key points and memory tricks that will help you gain mastery in science. For example

1. Myopia is the short-sightedness i.e. can only see near object clearly and can only be corrected using concave lens.

2. In the life history of Schistosomer (Bilharzia), snail is the secondary host.

3. The cerebrum is concerned with hearing, balance and muscular control.

4. Collagen fibres runs parallel to each other in bundles, they are connective tissue proteins.

5. Micronucleus (meganucleus) is not directly involved in sexual reproduction. The micronucleus in each animal disintegrates and eventually disappears into the cytoplasm.

6. Mosses, liverworts and ferns can be grouped together because they are seedless plants.

7. In spirogyra, the pyrenoid is used to store starch.
