What is a virus?

Ans 1:

A virus is a microscopic organism that can replicate only inside the cells of a host organism. Most viruses are so tiny they are only observable with at least a conventional optical microscope. Viruses infect all types of organisms, including animals and plants, as well as bacteria and archaea. Approximately 5000 different viruses have been described in detail at the current time, although it is known that there are millions of distinct types.  Viruses are found in virtually every ecosystem on Earth, and these minute life forms are thought to be the most abundant type of biological entity.  The study of viruses is known as virology, a specialty within the field of  microbiology.

Ans 2:

An infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host.

Ans 3:

A piece of code which is capable of copying itself and typically has a detrimental effect, such as corrupting the system or destroying data.

Ans 4:

Viruses are tiny organisms that may lead to mild to severe illnesses in humans, animals and plants. This may include flu or a cold to something more life threatening like HIV/AIDS.

What is cellular respiration?

Ans 1:

Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of thecell. The process occurs in two phases: glycolysis, the breakdown of glucose to pyruvic acid.

Ans 2:

Cellular respiration is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.

What is respiratory system?

Ans 1:

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe.

Ans 2:

The respiratory system (called also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for the process of respiration in an organism.

Why is literature important in everyday life?

Ans1

Literature is important in everyday life because it connects individuals with larger truths and ideas in a society. Literature creates a way for people to record their thoughts and experiences in a way that is accessible to others, through fictionalized accounts of the experience. As an art form, literature has existed for thousands of years, with the oldest texts dating back to the 26th century B.C.E.

Ans2

Literary tradition is both oral and written. Civilizations that existed without a written language still managed to pass down their stories through oral telling. Many Native American cultures practice an oral literary tradition. The primary use of literature in ancient settings was to pass down customs, beliefs and traditions to the younger generations. In more recent centuries, literature has taken on a more comprehensive role of mirroring society in order for humans to study themselves and understand the underlying truths common to all people. For students, studying literature is a critical component in education, as it teaches students to see themselves reflected in art. This allows people to learn about life and truth. Literature also helps people to see life from the perspective of another. Identity-based literature teaches the reader what life is like for others, helping them to be more understanding and respectful of those around them.

Why is biology important in everyday life?

Ans1:

Biology is important to everyday life because it allows humans to better understand their bodies, their resources and potential threats in the environment. Biology is the study of all living things, so it helps people to understand every organism alive, from the smallest bacteria to California redwoods and blue whales. Professional biologists often concentrate on a small subset of living organisms, such as birds, plants or bacteria.

Ans2:

The study of biology has helped humans to understand the similarities between all forms of life. For example, the genetic code that helps to construct all living organisms is very similar in all life forms. The genetic material is stored in the form of DNA for all plants, animals, bacteria and fungi. By studying the DNA of all these different life forms, biologists have determined that all living creatures are related to each other.

Biology has also helped doctors learn how to keep people healthy and fight off disease. Biologists have learned that things called pathogens, which are themselves other living entities, cause diseases. By understanding how these dangerous organisms work, scientists can fight them off. Because of biology, many people have lived long lives as they have been able to avoid diseases.

Importanceof Biology in our Daily Lives with Respect to Agriculture and Industry

1.      Agriculture plays great role narrating the importance of biology in our daily lives. Agriculture is largely the result of man’s taking the advantage of the inter relations of soil, climate and natural habitat to select those particular combinations that meet his basic requirements. Thus to provide necessary food, man depends entirely on green plants that can alone capture the solar energy.

2.      High yielding varieties of crop plants like rice, wheat, jute, sugar cane, pulses etc are now bred experimentally. Disease resistant grains and verbalized seeds are made.

3.      Biological control strategies are undertaken as pest control emphasizing the importance of biology in our daily lives.

4.      Modern man does not depend on fishing and hunting like our ancestors and instead rears fishes as well as cattle and various other domestic animals to get food and other necessities of life. This has resulted in the development of fishery and animal husbandry.

5.      The importance of biology in our daily lives lies in the production of clothings and timber for making furnitures, in supplied raw materials for paper, dyes, etc.

6.      Fossils are important in locating underground oil and natural gas reserves. Even coal and mineral oil formed from decomposed plant bodies are key to industrial prosperity.

Importance of Biology in our Daily Lives with Respect to Health and General well Being

1.      Medical advancement also shows the importance of biology in our daily lives. The study of dreaded diseases, their causative agents, cure as well as the actions of drugs are a way of biological enlightenment that strives minimizing human suffering.

2.      Importance of biology in our daily lives also lies in finding and curing hereditary abnormalities like haemophilia, Down’s syndrome,etc.

3.      Biology aims in making effort to better human race through eugenics.

4.      Biology study has a vital role in controlling environmental pollution and attracted sense of art and beauty.

Give a brief account of Newton’s law of motion.

Newton’s law of motion is given below-

In 1687 in his book Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) the greatest English physicist Sir Isaac Newton first introduce the three laws of motion.

The laws are-

1. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

2. The vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration vector a of the object. Mathematically we can express the law as F=ma.

3. Every action has an equal and opposite reaction. In other word we can say that when one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
