It is said that genes control the characteristic or trait but the question arises how ? The genes control the characteristic by making a specific protein. Genes are the segment of DNA that contains information to form RNA which ultimately forms protein. Each gene contains two alleles and this instructs the cell to make protein for expression of traits.
If the plant has gene for green seeds then it will make protein which will give green colour to seeds.

Any compound contains chemical energy that can be released when its chemical bonds are broken. Any substance that can be used as a fuel contains chemical energy. Examples of matter containing chemical energy include:
- Coal: Combustion reaction converts chemical energy into light and heat.
- Wood: Combustion reaction converts chemical energy into light and heat.
- Petroleum: Can be burned to release light and heat or changed into another form of chemical energy, such as gasoline.
- Chemical batteries: Store chemical energy to be changed into electricity.
- Biomass: Combustion reaction converts chemical energy into light and heat.
- Natural gas: Combustion reaction converts chemical energy into light and heat.
- Food: Digested to convert chemical energy into other forms of energy used by cells.
- Cold packs: Chemical energy is absorbed in a reaction.
- Propane: Burned to produce heat and light.
- Hot packs: Chemical reaction produces heat or thermal energy.
- Photosynthesis: Changes solar energy into chemical energy.
- Cellular respiration: A set of reactions that changes the chemical energy in glucose into chemical energy in ATP, a form our bodies can use.

In transverse waves, the particles transfer energy from one point to another point by vibrating perpendicularly in the direction of the propagation of the wave. What it means is that in transverse waves movement of particles are at right angles to the movement of energy.
In a transverse wave, the particles are displaced perpendicular to the direction that the wave travels. Examples of transverse waves include vibrations on a string and ripples on the surface of the water. We can make a horizontal transverse wave by moving the slinky vertically up and down. Radio wave, water waves are a few examples of transverse waves.

Homologous organs: These are organs having a similar structural plan, but different functions. For example, the wing of a bat, the flipper of a seal, the front leg of a horse and the arm of a man perform different functions, but have the same structural plan.

Prime factorisation of 420 = 2 × 2 × 3 × 5 × 7
Prime factorisation of 130 = 2 × 5 × 13
HCF of 420 and 130 = 2 × 5 = 10
LCM × HCF = Product of the Numbers
10 × LCM = 420 × 130
LCM = 420 × 13 = 5460
