Random sampling refers to the method in which each of the sampling unit (units in the population) has a non-zero probability of being selected into the sample. Simple random sampling is a special case of random sampling when each of the sampling unit has equal chance of being selected.
Non random sampling is a method of sampling wherein, it is not known that which individual from the population will be selected as a sample.

Evidence that supports the theory
- The Matching of Continents (Jig-Saw-Fit): The shorelines of Africa and South America facing each other match remarkably.
- Rocks of Same Age Across the Oceans: radiometric dating methods have correlated the rock formation in different continents.
- Tillite: The glacial tillite found in Gondwana system of sediments has its resemblance to six different landmasses of the Southern Hemisphere. Counterparts of this succession are found in Africa, Falkland Island, Madagascar, Antarctica and Australia besides India.
- Placer Deposits: The placer deposits of gold in the Ghana coast do not have source rock in the region. The gold deposits of Ghana have been derived from the Brazil plateau when the two continents lay side by side
- Distribution of Fossils: identical species of plants and animals adapted to living on land or in freshwater are found on either side of the marine barriers. For example remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early Permian (between 286 and 258 million years ago), are found solely in Southern Africa and Eastern South America.

Connective tissue is a major supporting tissue in the body that provides structural framework and support to different tissues. Blood is regarded as a connective tissue because as the blood is circulated throughout the body due to pumping action of heart, it carries different materials and gases from one part of the body to another. Hence, it connects different tissues and organs of the body and thus, called as a connective tissue.

Nervous or the nerve tissue is the main tissue of our nervous system. It monitors and regulates the functions of the body. Nervous tissue consists of two cells: nerve cells or <a href="https://byjus.com/biology/neurons/">neurons</a> and glial cells, which helps transmit nerve impulses and also provides nutrients to neurons. Brain, Spinal Cord, and nerves are composed of nervous tissue, they are specialized for being stimulated to transmit stimulus from one to another part of the body rapidly.
Structure Of Nervous Tissue
- It is made of nerve cells or neurons, all of which consists of an axon. Axons are long stem-like projections emerging out of the cell, responsible for communicating with other cells called the Target cells, thereby passing impulses
- The main part is the cell body which contains the nucleus, cytoplasm and cell organelles. Extensions of the cell membrane are referred to as processes.
- Dendrite is a highly branched processes, responsible for receiving information from other neurons and synapses (specialized point of contact). Information of other neurons is provided by dendrites to connect with its cell body.
- Information in a neuron is unidirectional as it passes through neurons from dendrites, across the cell body down the axon.

Muscular tissue is a specialized tissue in animals which applies forces to different parts of the body by contraction. It is made up of thin and elongated cells called muscle fibers. It controls the movement of an organism.
The cytoplasm in the muscle fibers is called sarcoplasm. It contains a network of membrane called the sarcoplasmic reticulum. The membrane surrounding the muscle fibers is called sarcolemma.
Properties of Muscular Tissue
-
Contractibility– It is the ability of muscle cells to shorten forcefully.
-
Extensibility– A muscle has the ability to be stretched.
-
Elasticity– The muscles have the ability to recoil back to its original length after being stretched.
-
Excitability– The muscle tissue responds to a stimulus delivered from a motor neuron or hormone.
Types of Muscular Tissue
The muscular tissue is of three types:
-
Skeletal Muscle Tissue
-
Smooth Muscle Tissue
-
Cardiac Muscle Tissue

- Glandular epithelium is a type of epithelial tissue which covers the glands (both exocrine and endocrine) of our body. Their main function is secretion. Both endocrine and exocrine glands produce their secretions through the glandular epithelium via special cells called goblet cells.
- Glandular epithelium in the reproductive tract is called endocervical glandular epithelium and helps in sexual functions by secreting lubricating fluid during sexual excitation.
- The glandular epithelium also lines the intestine where it helps in the absorption of nutrients. Thus it aids in digestion. Thus glandular epithelium is a multifunctional tissue that combines with other tissues to perform vital functions of the body.

| TYPES OF TISSUES | STRUCTURE | FUNCTION | EXAMPLE |
| Simple Squamous | It forms a single layer of flat cells which is in contact with the basal lamina. | It helps in the filtration or diffusion of molecules. | Lining of Bowman's capsule |
| Simple Cuboidal | It forms a single thick layer and is made of cube-shaped cells. | It helps in secretions. | Lines the salivary glands |
| Simple Columnar | It forms a uni-layered, elongated shaped cells. | It helps in the secretion of digestive fluids and absorbs nutrients. | Lining layer of intestinal mucosa |
| Pseudostratified | It appears 2-3 layered (but in actual it is single layered). | It helps in removing mucus. | Lines the respiratory tracts |
| Stratified Squamous | It consists of squamous (flattened) epithelial cells arranged in layers over a basal membrane. | It forms a protective layer, block diffusion/microbes. | Epidermis of skin |
| Transitional | The shape of the surface cells changes/ transition depending on the degree of stretch. | It allows considerable stretching. | Lining of the urinary bladder |

Where earthquake waves are not reported, such zones are called earthquake shadow zones.
It is observed that seismographs located beyond 103° from the epicenter do not record the earthquakes.
Seismographs located beyond 142° again record ‘p’ waves only.
The entire zone beyond 142° do not receive ‘s’ waves
The shadow zone of ‘s’ waves is much larger than the ‘p’ waves it is equal to 40% of the earth surface

Any valuable thing which has monetary value and owned by a business, is its asset. In other words, assets are the monetary values of the properties or the legal rights that are owned by the business organisations.
Fixed Assets− These are those assets that are hold for the long term and increase the profit earning capacity and productive capacity of the business. These assets are not meant for sale, for example, land, building machinery, etc.
Current Assets− Assets that can be easily converted into cash or cash equivalents are termed as current assets. These are required to run day to day business activities; for example, cash, debtors, stock, etc.
Tangible Assets− Assets that have physical existence, i.e., which can be seen and touched, are tangible assets; for example, car, furniture, building, etc.
Intangible Assets− Assets that cannot be seen or touched, i.e. those assets that do not have physical existence, are intangible assets; for example, goodwill, patents, trade mark, etc.
Liquid Assets− Assets that are kept either in cash or cash equivalents are regarded as liquid assets. These can be converted into cash in a very short period of time; for example, cash, bank, bills receivable,Flexible Investments etc.
Fictitious Assets− These are the heavy revenue expenditures, the benefit of whose can be derived in more than one year. They represent loss or expense that are written off over a period of time, for example, if Research and Development expenditure is Rs 1,00,000 for 5 years, then each year Rs 2,00,000 will be written off.
