Computer security basically is the protection of computer systems and information from harm, theft, and unauthorized use. It is the process of preventing and detecting unauthorized use of your computer system. "Unauthorized access" entails approaching, trespassing within, communicating with, storing data in, retrieving data from, or otherwise intercepting and changing computer resources without consent. These laws relate to these and other actions that interfere with computers, systems, programs or networks. 

Weeds can be defined as the unwanted plants that are grown in the field and harm the desired crops. Cyperinus is the most invasive weed found throughout the world. It is the weed of rice field. This is the weed which is commonly found in the temperate regions. A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place". Examples commonly are plants unwanted in human-controlled settings, such as farm fields, gardens, lawns, and parks.

Cell is the basic structural and functional unit of life

A cell is a functional, structural and fundamental unit of life

A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known organisms. A cell is the smallest unit of life. ... Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids. A cell consists of a nucleus and cytoplasm and is contained within the cell membrane, which regulates what passes in and out. The nucleus contains chromosomes, which are the cell's genetic material, and a nucleolus, which produces ribosomes.

The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.” 

Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network. 

 

During the polymerization process, some chemical groups may be lost from each monomer. 

 

The distinct piece of each monomer that is incorporated into the polymer is known as a repeat unit or monomer residue.

1. It enables us to select only healthy seedlings for the plants.

3. It promotes better development of shoot system of plants.

4. The process of transplantation enables us to plant the seedlings at the right spacing so as to ensure the uniform availability of water, nutrients and sunlight to the plants.

Minerals are naturally occurring substances that have a definite chemical composition. Minerals are formed in different  types of geological environments, under varying conditions. Minerals can be identified on the basis of their physical properties such as colour, density, hardness and chemical property such as solubility. Minerals are distributed in rocks and sea bed also. Tropical regions are very rich in terms of mineral resources.  Types of Minerals: On the basis of composition, minerals are classified into metallic and non-metallic types. Metallic, minerals contain metals in raw form. Metals are hard substances that conduct heat and electricity and have lustre or shine. For example, iron ore and bauxite. Metallic minerals are of two types: (a) Ferrous and (b) Non-ferrous. Ferrous minerals contain iron ore, manganese and chromites. Most of the Iron and steel industries and heavy industries depends on this mineral. Non-ferrous minerals do not contain iron but may contain some other metals like gold, silver, copper or lead.  Non-metallic minerals do not contain metals. For example, limestone, mica, gypsum, coal and petroleum.  Mining, drilling and quarrying are the three extraction methods of minerals. Mining is the process of taking out minerals from rocks buried under the earth’s surface. The process of mining includes two methods: (a) Open cast mining, (b) Shaft mining Deep wells are bored to take minerals out and this process is called drilling. In the process of quarrying, minerals that lie near the surface are simply dug out. Mineral based industries are the backbone of industrial development of a naion. Mining needs cheep labour and resources to extract it off. Distribution of Minerals: Minerals are found in igneous rock, metamorphic rocks and sedimentary rocks. Iron ore, nickel, copper minerals are found in igneous and metamorphic rocks. Limestone is found in sedimentary rocks. Plateau region of India such as Daccan and chota nagpur plateau provides the rich level of mineral distribution. Uses of Minerals: Some minerals  which are usually hard are used as gems for making jewellery. Copper is used in almost everything from coins to pipes. Silicon is used in almost everything from coins to pipes. Silicon is used in the computer industry which is obtained from quartz. Aluminium is used in automobile, airplanes, bottling industry, building and in kitchen cookware. Mica is used to make electrical appliances and glass making industries. Iron and steel is used in every indurstry. Distribution of Minerals in India: Iron: Jharkhand, Odisha and Chattisgarh Bauxite: Jharkhand, Odisha and Chattisgarh Mica: India is the leading producer of mica in the world. Jharkhand, Bihar, Andhra Pradesh are major producing states. Gold: Kolar in Karnataka  Conservation of Minerals: Minerals are the non-renewable resources. It is necessary to reduce wastage in process of mining. Recycling of metals is the way to conserve mineral resources. over exploitation is harmful for environment as well.  · Power Resources: Power resources are of two types: (a) Conventional Resources, (b) Non-conventional Resources We need power resources for industry,domastic use, agriculture, transport, communication and defence. Conventional Sources of Minerals: The energy resources which have been in common use for a long time are known as conventional sources. Firewood and fossil fuels are two main conventional energy sources. Fossil fuels comprises of Coal( known as burried sunshine), Patroleum (known as black gold), Natural Gas and Hydroelectricity. Non-Conventional Sources of Minerals: Non-conventional sources of energy are renewable in nature. Solar energy, wind energy, tidal energy, etc. are  the examples of non-conventional sources of energy. They are more expensive  as it needs technological upgradation. India has a great potential for Solar energy.

Distribution of Minerals:

1. Minerals are found in igneous rock, metamorphic rocks and sedimentary rocks.
2. Iron ore, nickel, copper minerals are found in igneous and metamorphic rocks.
3. Limestone is found in sedimentary rocks.
4. Plateau region of India such as Deccan and chota Nagpur plateau provides the rich level of mineral distribution.

Uses of Minerals:

1. Some minerals which are usually hard are used as gems for making jewellery.
2. Copper is used in almost everything from coins to pipes.
3. Silicon is used in almost everything from coins to pipes.
4. Silicon is used in the computer industry which is obtained from quartz.
5. Aluminum is used in automobile, airplanes, bottling industry, building and in kitchen cookware.
6. Mica is used to make electrical appliances and glassmaking industries.

There are two more methods- 1. Quarrying 2. Drilling

The mining process involves the excavation of large amounts of waste rock to remove the desired mineral ore. The ore is then crushed into finely ground tailings for chemical processing and separation to extract the target minerals. 

The primary methods used to extract minerals from the ground are: 

1. Underground mining
2. Surface (open pit) mining
3. Placer mining 

The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

Higher-grade metallic ores found in veins deep under the Earth’s surface can be profitably mined using underground methods, which tend to be more expensive. Large tabular-shaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well. The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock.

Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods, which generally cost less than underground methods. Many industrial minerals are also mined this way, as these ores are usually low in value and were deposited at or near the Earth’s surface. In a surface mine, hard rock must be drilled and blasted, although some minerals are soft enough to mine without blasting. 

Mineral as a “homogenous, naturally occurring substance with a definable internal structure. These are found in varied forms in nature, ranging from the hardest diamond to the softest talc. Minerals are usually found in 'ores'.

Mineral is defined as a “homogenous, naturally occurring substance with a definable internal structure.” Minerals are found in varied forms in nature, ranging from the hardest diamond to the softest talc. Rocks are combinations of homogeneous substances called minerals.

Mode of Occurrence of Minerals

Minerals are usually found in “ores”. The term ore is used to describe an accumulation of any mineral mixed with other elements. Minerals generally occur in the following forms:

• In igneous and metamorphic rocks, minerals may occur in the cracks, crevices, faults or joints.
• In sedimentary rocks, a number of minerals occur in beds or layers.
• The decomposition of surface rocks and the removal of soluble constituents also forms the minerals.
• Minerals also occur as alluvial deposits in sands of valley floors and the base of hills.
• The ocean waters contain vast quantities of minerals.

Classification of Minerals

In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. The star network is one of the most common computer network topologies. The hub and hosts, and the transmission lines between them, form a graph with the topology of a star. A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down.

COMPOUNDED HALF YEARLY- Principal= rs. 10,000 Rate= 5% per half year Time= 3 half years. Amount=Principal(1+Rate/100)time(in power) =10,000(1+5/100) 3(in power) =10,000*105/100*105/100*105/100 =(105*105*105)/100 =11,57,625/100 =11576. 25 Compound Interest=Amount-Principal =11576.25-10,00 =1576.25 COMPOUNDED ANNUALY- Principal=10,000 Rate= 10% per annum Time= 1(1/2) years. (first, we will find the interest for 1 year and then for half year.) (As time is 1 year, the SI=CI. So, to make our calculation easier, we are going to find it in simple interest only) Simple Interst= (principal*time*rate)/100 =(10,000*1*10)/100 =1000 Amount= principal+Interest =10,000+1000 11000 (for next half year, the amount becomes principal in CI ie 11000 becomes our new principal.) Intesrest= PRT/100 =(11000*10*1)/(100*2) =110*5 =550 Thus, for 1 and a half years compounded annually, our interest comes out to be rs. 550. Comparing the Interests- 1576. 25>550 Difference = 1576.25-550 =rs. 1026.25. Thus,the compound interest will be more if the principal is compounded half yearly.

To draw a line segment of a given length, we can employ either of the given methods:

• Using a ruler
• Using ruler and compasses

Using a Ruler

We are required to draw a line segment of length 5 cm. The simplest method is by using a ruler. We mark two points using a ruler which are at a distance of 5 cm from each other. Then, mark the points as A and B and join them. We get a line segment AB of length 5 cm

However, it is to be noted that if we do not look straight down at the ruler, we might end up capturing an incorrect distance. A more accurate method for the same is described below.

Using Ruler and Compasses

The steps to draw a line segment of length 5 cm using ruler and compasses are:

• Step 1: Draw a line of any length. Mark a point A on the line, which is the starting point of the line segment.
• Step 2: Using a ruler, place the pointer of the compass 5 cm apart from the pencil’s lead.

• Step 3: Place the pointer of the compass at A and mark an arc on the line with the pencil point.

• Step 4: Mark the point where the arc and the line intersect at B.
• Step 5: AB is the required line segment of length 5 cm.

Cells constitute various components of plants and animals. A cell is the smallest unit of life and is capable of all living functions. Cells are the building blocks of life. This is the reason why cells are referred to as ‘the basic structural and functional unit of life’. All cells vary in their shapes, sizes, and activities they perform. In fact, the shape and size of the cell is related to the specific function it performs.
