Weeds are unwanted plants. They grow with crops and compete for nutrients and water with main crop. So weeds are very harmful. Process of controlling the weed is called weeding. Weeding is done manually by using khurpi and by using mechanical machines. Weeds are also controlled by using some chemical substances like 2, 4-D. These chemicals are called weedicides and are used to kill and destroy the weeds.

- Strong
Synthetic fibres are strong so they can take up heavy things easily. - Retain their original shape
Synthetic fibres retain their original shape so it's easy to wash and wear. - Elastic
Can easily be stretched out. - Soft
Synthetic fibres are generally soft so they are used in clothing materials. - Colour
Varieties of colours are available as they are manufactured. - Cost
Clothes made by synthetic fibres are generally cheaper than those made by natural fibres.
- Does not absorb moistures
Synthetic fibres do not absorb sweat, trapping heat in our body. - Rough feel
Synthetic fibres may give rough feel, making it unsuitable for pyjamas, underwear, etc.
<div>Advantages and Disadvantages of Natural Fibre</div> <div> </div> <div>Advantages</div>
- Comfortable
Clothes made by natural fibres are more comfortable than those made by synthetic fibres. - Environment
Producing materials from natural fibres are less harmful to our environment. - Fire resistant
Natural fibres are resistant to fire but polymer based fibres will melt.
- Expensive
Materials produced by natural fibres are generally expensive as synthetic fibres can be made easily by manufacturing. - Shrink
Natural fibres might shrink due to aggressive washing.

1. Ductility can be said to be the property of a material to stretch without getting damaged. Malleability can be said to be the property of a material to deform under compression.
2. Ductility also refers to the ability of a metal to change its form under tensile stress. Malleability refers to the ability of a metal to change its form under compressive stress.
3. A metal’s ductility is measured by looking at its tensile strength. The bend test is the commonly used test for determining the ductility of a metal.
4. A metal’s malleability is measured by looking at how much pressure it can withstand without breaking.
5. Metals having ductile property can be stretched into wires. The metals having malleable property can be rolled or beaten into sheets.

Yawning is a mostly involuntary process of opening the mouth and breathing in deeply, filling the lungs with air. It's a very natural response to being tired. In fact, yawning is usually triggered by sleepiness or fatigue. Certain conditions can cause a vasovagal reaction, which results in excessive yawning. Some evidence suggests that yawning is a means of communicating changing environmental or internal body conditions to others. Still, low oxygen levels in the paraventricular nucleus (PVN) of the hypothalamus of the brain can induce yawning. Another hypothesis is that we yawn because we are tired or bored.

The amount of heat energy produced on completely burning one Kilogram of fuel (in 02) is called the calorific value of a fuel. The more is the calorific value of a fuel, more is the efficiency of the fuel. The calorific value of the fuels is expressed in Kilojoules per kilogram (kJ/kg) or kilojoules per gram (kJ/g).

The differences between internal fertilization and external fertilization are:
i. Internal fertilization takes place inside the body of the female while the external fertilization takes place outside the body of the female.
ii. In case of internal fertilization sperms are ejaculated in female’s body by the male. In external fertilization sperms are discharged outside the body of the female.

Types of plastics: Plastics are of two types – thermoplastics and thermosetting plastics.
- Thermoplastics – Thermoplastics get soft when heated and hard again when they are cooled. Example – polythene and poly vinyl chloride. Such plastics are used in making toys, containers, plastic bags, raincoats and combs. Thermoplastics are used in making those articles which do not get too hot, and are flexible.
- Thermosetting plastics – Thermosetting plastics get soft only one, the first time they are heated after being made. When such plastics are heated for the first time, they become soft and can be moulded to make an article of any desired shape. On cooling, the article becomes hard and rigid. Example – Bakelite and melamine. They are used in making handles of cooking utensils, plates, cups, floor tiles, electrical fittings, telephone instruments, etc.

A fertiliser is an inorganic salt.Fertilisers are prepared in factories.they have all the three important plant nutrients nitrogen, phosphorous and potassium. They do not emit any bad smell but they cause alot of pollution.ex ammonium sulphate . A fertiliser does not provide any humus to the soil.
Manure is a natural substance obtained by the decomposition of cattle dung, human waste and plant residues. Manure is a natural product. it is prepared naturally in the field. And it mostly doesn't have the three important plant nutrients . Manure provides a lot of humus to the soil.
