In five kingdom classification(scheme proposed by R. Whittaker in 1969), Protists make up a kingdom called “Protista”, composed of “Organisms which are unicellular or unicellular-colonial and which form no tissue.
Protists are the eukaryotes that are not members of the kingdom Plantae, Animalia or Fungi. Most Protists are unicellular, but few have hundreds or even thousands of cells.
Protists can be autotrophic or heterotrophic.
They move by cilia, flagella or pseudopodia.

Here are some of the MCQs which will help you while studying and preparing exams of Evolution. This file contain 220 MCQs which will revise your complete study of evolution.
The chordates are named for the notochord: a flexible, rod-shaped structure that is found in the embryonic stage of all chordates and also in the adult stage of some chordate species.
It is located between the digestive tube and the nerve cord, providing skeletal support through the length of the body.
In some chordates, the notochord acts as the primary axial support of the body throughout the animal's lifetime.

• Bioremediation – process of cleaning up environmental sites contaminated with chemical pollutants by using living organisms to degrade hazardous materials into less toxic substances
• Nutrient cycles referred to as biogeochemical cycles
• Gaseous forms of carbon, oxygen, and nitrogen occur in the atmosphere and cycle globally
• Less mobile elements, including phosphorous, cycle on a more local level
• Still, gains and losses from outside of the ecosystem are generally small when compared to the rate at which nutrients are cycled within the system.
ART refers to methods used to achieve pregnancy by artificial or partially artificial means.
• INCLUDES- artificial insemination, In vitro fertilization (IVF) , Zygote intrafallopian transfer (ZIFT) or Tubal Embryo Transfer, Gamete intrafallopian transfer (GIFT) , Intracytoplasmic sperm injection (ICSI)
There needs to be a balance between water ingested and water eliminated.
In order to maintain homeostatic levels of water, the body must undergo osmoregulation.
A number of morphologically and functionally diverse organs and tissue organs and tissue contribute to the development of immune responses .
These organs can be distinguished by function as the primary and secondary lymphoid organs .
Microbial cultures are foundational and basic diagnostic methods used extensively as a research tool in molecular biology.
Microbial cultures are used to determine the type of organism, its abundance in the sample being tested, or both.
It is one of the primary diagnostic methods of microbiology and used as a tool to determine the cause of infectious disease by letting the agent multiply in a predetermined medium.
It is often essential to isolate a pure culture of microorganisms

Honey bees are social insects, which means that they live together in large, well-organized family group.
Communication, complex net construction, environmental control, defense and divison of the labor are just some of the behaviour that honey bees have developed to exist successfully in social colonies.
A honey bees colony typically consists of three kinds of the bees 1) Queen. 2) Workers. 3) Drones.
In addition to thousands of workers adults, a colony normally has a single queen & several hundred drones.
Honey bees live in comb or nest.
Mutual cooperation exist.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

3. Introduction
In five kingdom classification(scheme proposed by R. Whittaker
in 1969), Protists make up a kingdom called “Protista”, composed
of “Organisms which are unicellular or unicellular-colonial and
which form no tissue.
Protists are the eukaryotes that are not members of the kingdom
Plantae, Animalia or Fungi. Most Protists are unicellular, but few
have hundreds or even thousands of cells.
Protists can be autotrophic or heterotrophic.
They move by cilia, flagella or pseudopodia.
4. History
John Hogg – He proposed kingdom Protoctista for microorganisms in 1961.
Ernst Haeckel – He suggested kingdom Protista inn 1996. He included
bacteria and all other microorganisms like amoeba in this kingdom.
Herbert Copeland – He separated prokaryotes from the kingdom Protista in
1966 and raised the prokaryotes to a status of separated kingdom.
Robert Whittaker – He gave five kingdom classification system in 1969. He
included unicellular eukaryotes in kingdom Protista.
Margulis and Schwartz – They modified the five kingdom classification
system in 1982. They also included colonial and simple multicellular
organisms in kingdom Protista.
Now, kingdom Protista have unicellular, colonial and simple multicellular
organisms.

ENVIRONMENT (Plant like
Protists
Produce large amount of oxygen.
Critical to marine food webs.
Maintains carbon cycle.
Help in decomposition.
Shows symbiosis ( Corals, Lichens)
15. ALGAL BLOOMS
Increase temperature and increase in nutrients (nitrates and
phosphates) leads to increased algal population.
Harmful to fishes and human (red tide).
PROTISTS AND THE INDUSTRY
Food source (kelps and sea weeds).
By-products used in cosmetics, drugs and gelatins.
Agar polysaccharides from cell wall of red algae.
Diatoms shell is used as abrasive.
16. PROTISTS AND HUMAN HEALTH
(Animal like protists)
MALARIA – Caused by Plasmodium.
SLEEPING SICKNESS – Caused by Trypanosoma and spread
by Tsetse fly.
