Biofuels are designed to replace gasoline, diesel fuel and coal, which are called “fossil fuels” because they are made from animals and plants that died millions of years ago. Biofuels are made mostly from plants that have just been harvested. There are three main types of biofuel. Ethanol, biodiesel, and biojet fuel.

Acetic acid, also known as ethanoic acid or methanecarboxylic acid, is a colorless liquid with a strong and distinct pungent and sour smell. Its chemical formula is C2H4O2 or can be written as CH3COOH or CH3CO2H. Acetic acid is used in many industrial processes for the production of substrates and it is often used as a chemical reagent for the production of a number of chemical compounds like acetic anhydride, ester, vinyl acetate monomer, vinegar, and many other polymeric materials.

The middle ear is composed of a stretched membrane and three small bones. The stretched membrane is called the ear drum When sound wave comes to the middle ear, it sets vibrations in the ear drum. After that, sound waves are transferred from ear drum transfers these vibrations to the three bones.

Displacement reaction is a reaction in which a more reactive element displaces a less reactive element from its compound
Ex: copper sulphate + Iron → Iron sulphate + copper
In the above reaction iron is more reactive than copper so iron replaces copper from copper sulphate.

An object's change in position with respect to time is known as its displacement. Velocity can be thought of as the object's speed and direction, or change in position over time. The acceleration of an object is equal to the derivative of its velocity and describes the object's change in velocity over time.If an object moves relative to a reference frame—for example, if a professor moves to the right relative to a whiteboard, or a passenger moves toward the rear of an airplane—then the object's position changes. This change in position is known as displacement.

Ribosomes are the cell organelles found inside the cell and composed of RNA and Proteins. They may found suspended in the cytosol, called free ribosomes or bound to the endoplasmic reticulum, called bound ribosomes. They help in protein synthesis.
Ribosomes are typically composed of two subunits, a large subunit and a small subunit. These two subunits join together when the ribosome attaches to messenger RNA (mRNA) during protein synthesis. Ribosomes along with another RNA molecule, transfer RNA (tRNA), help to translate the protein-coding genes in mRNA into proteins.

- Mitochondria are the powerhouse of the cell because they supply power (energy) to all the cell of the body.
- All living cells have mitochondria (cell organelle), are responsible for producing energy (called ATP) that the cell needs to function.
- They are like power stations in our bodies, supplying energy to all cells for proper functioning.
- If our cells do not have energy, then the tissues or body organs that are made up of cells do not work properly, in the same way that if power stations do not produce enough energy for the country there will be areas of blackout, where parts of the country cannot function.

Cytoplasm is a thick jelly-like fluid inside the cell membrane. Nearly 80% of the cytoplasm is water. It occupies the space between the cell membrane and the nucleus. All the life functions take place in the cytoplasm. There are many small cytoplasmic bodies in cytoplasm. These are called cell Organelles. All organelles in cytoplasm play an active role in the functioning of the cell.

All eight planets in the Solar System orbit the Sun in the direction of the Sun's rotation, which is counterclockwise when viewed from above the Sun's north pole. Six of the planets also rotate about their axis in this same direction. The gravity from the sun causes our planet to move in a curved, elliptical path. Thankfully, the planets are moving fast enough so that they are not pulled into the sun, which would destroy Earth. On the other hand, we are also not moving quickly enough to escape the sun's pull.

A planet is round because of gravity. A planet's gravity pulls equally from all sides. Gravity pulls from the center to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three-dimensional circle. Our planets have continued spinning because of inertia. In the vacuum of space, spinning objects maintain their momentum and direction their spin because no external forces have been applied to stop them.
