Define the terms:
What is Biology? Name and define its three major branches.
Biology is one of the major branches of science. It is a natural science which deals with study of living beings, that is to say animals, plants and even humans. Biology is derived from two Greek words: 'bios' meaning life and 'logos' meaning study. Biology on the whole can be sub-divided into three major branches, namely:
How does Biology help us in leading a healthier life?
Knowledge of biology has greatly helped us in the field of human health. It provides to individuals and society, the knowledge that enables us to live a proper life. Basic knowledge can help in self-analyzing causatives of diseases, different microbes causing diseases. Thereby examining and studying their mode of living and propagating diseases. This study has paved the way for production of new drugs synthesized naturally or synthetically killing causatives of diseases.
A farmer and a housewife may have never studied biology, yet both of them know some of its general principles through experience. State any two principles which they know.
A farmer, although has never studied biology, knows by his experience how to increase his produce. He knows how to plough and plant crops and select good quality seeds for sowing. Right from selecting germfree seeds to sow, act of ploughing, crop plantation, using fertilizers, irrigation and its types, crop harvesting, cross-breeding with other plants, weed removal, etc, they have knowledge of basic biological concepts.
A housewife, by using her experience knows which fruit or vegetable to grow and how much time. She knows all the nutritional values of various foodstuffs. She can suggest first hand treatment for simple cold, cough and other mild mishaps. She knows to tame some useful animals like cow, goat and dog for her maximum benefit.

Do you think Biology can help in further increasing the yield of food? If so, how?
Yes, Biology can help in further increasing the yield of food. New varieties of plants and new breeds of cattle, poultry, etc. are being developed with the knowledge of Biology. The science has also increased our knowledge of diseases of plants and animals, and how to cure them. Plants and animals of newer varieties are cultivated by cross-breeding through the application of biotechnological principles, unleashing unexplored concepts for a brighter future. All these efforts are helping us to produce more food in fields, dairies and poultry farms.
Assertion (A): Ichthyology and Pisciculture are the same branches of zoology as both of them are related to fishes.
Reason (R): Both the branches are different as they deal with different types of fishes.
A is false but R is true.
Reason — A is false because Ichthyology and Pisciculture are not the same. Ichthyology is the scientific study of fish, while Pisciculture is the technique of growing fish. Both the branches are different.
R is true as both the branches are different as they deal with different types of fishes.
Therefore, A is false but R is true is the correct option.
Assertion (A): The study of the effects of radioactivity on living things is termed as Nuclear Biology.
Reason (R): It is also known as Radiation Biology as radioactive rays emit from the nucleus of the elements.
A is False and R is True
Reason — A is False the correct term is Radiation Biology (or Radiobiology), not Nuclear Biology.
R is True as radioactive rays emit from the nucleus of the elements so, it is called Radiation Biology.
Therefore, A is False and R is True is the correct option.
Assertion (A): The term viviparous is normally used for mammals who give birth to young ones.
Reason (R): None of the mammals are oviparous.
A is True and R is False.
Reason — A is True because animals who give birth to young ones rather than laying egg are known as viviparous animals.
R is False as most of the mammals are viviparous but there are some exception like platypus which is oviparous (lays eggs).
Therefore, A is True and R is False is the correct option.
Assertion (A): Pathology helps in the detection of diseases of plants and animals.
Reason (R): Pathological tests cover tests on blood, bodily tissues, urine, stools (faeces).
Both A and R are true and R is the correct explanation of A.
Reason — A is true as pathology is the study of diseases, including their causes, development, and effects on plants and animals.
R is true as pathology involves analyzing body fluids and tissues to diagnose diseases.
Therefore, Both A and R are true and R is the correct explanation of A is the correct option.
Assertion (A): Phycology is the study of algae.
Reason (R): Algae are simple, chlorophyll-containing organisms found mainly in aquatic habitats.
Both A and R are true but R is not the correct explanation of A.
Reason — A is true because Phycology is indeed the branch of biology that deals with the study of algae.
R is true as algae are simple, chlorophyll-containing organisms found mainly in aquatic habitats.
However, this reason only describes algae; it does not explain why the study of algae is called phycology.
Therefore, Both A and R are true but R is not the correct explanation of A. is the correct option.
