Study Notes
Digestive System
- The human digestive system consists of hollow organs connected from mouth to anus
- Organs include mouth, esophagus, stomach, small intestine, large intestine, and anus
- The system includes associated organs like liver, pancreas, and gall bladder
Eye Structure and Function
- X is the retina
- The cornea produces maximum refraction of light rays
- A real and inverted image is formed on the retina
- The function of the pupil is to regulate the amount of light that enters the eye
Metal Reactivity
- Metals P, Q, R, S were tested for reactivity
- Metal R can be cut with a knife
- Metal P forms M₂O₃ oxide, reacting with both acids and bases
- P does not react with cold or hot water but reacts with steam
- Q reacts with hot water and floats
- R reacts violently with cold water
- S does not react with water
- Metal S needs to be stored in kerosene
- Metal Q is potassium
- Metal R forms amphoteric oxides
- The increasing order of reactivity is S < P < Q < R
