d. Discuss the different applied subjects of Biology

a. Carolus Linnaeus was professor of subject?

Carolus Linnaeus was a professor of Medicine.

b. What was the objective of Taxonomy?

The aim of classification is to acquire knowledge of every group and subgroup of each organism. To document the accumulated information systematically focusing on the diversity of living organisms, introduce the total knowledge concisely and take proper steps after identifying organisms to conserve them or increase the number of species for the well-being of human beings and the living world are the objectives of classification.

C. Classify the physical branch of Biology.

The following are the classification of physical Biology;

i. Morphology: The field deals with the form and structure of organisms. It is usually divided into two branches — external and internal morphology. The external description of the body is called external morphology and the internal description of the body is called internal morphology.

ii. Taxonomy: Classification of organisms and the principles related to this task are discussed in the field.

iii. Physiology: This branch of biology deals with the biochemical activities of different organs of organisms. Besides, detailed description of all the physiological process of organisms is found in it.

iv. Histology: The microscopic structure, arrangement and function of plant and animal tissues are studied in this subject.

v. Embryology: The branch of biology that discusses the development of embryo of organisms.

vi. Cytology: The structure, function and division of an individual cell in a body of organisms are studied in this field of biology.

vii. Genetics: The branch of biology which deals with genes and heredity.

viii. Evolution: The gradual development of life and organisms over successive generations on earth is studied in this subject.

ix. Ecology: It is the science of the reciprocal relationship between organisms and their environment.

x. Endocrinology: The field of science deals with the study of endocrine glands and hormones secreted by them in a body of organisms.

xi. Bio-geography: The branch of biology studies the geographical distribution of organisms, past and present, throughout the landscape of planet earth including the knowledge of classifying bio-geographical patterns.

d. Discuss the different applied subjects of Biology

The followings are the applied subjects of Biology. These subjects are related to life are included in this category, and some of them are mentioned below:

i. Paleontology: Science of the prehistoric life forms and fossils;

ii. Biostatistics: Science of statistics of organisms;

iii. Parasitology: Science related to parasitism, life process of parasitic organisms and diseases caused by them;

iv. Fisheries: Science dealing with fish, harvesting of fish, management and conservation of fish assets;

v. Entomology: Science related to the study of life, merit, demerit, and control of insects including the losses caused by them;

vi. Microbiology: Science related to virus, bacteria, fungi and other microorganisms;

vii. Agriculture: Science concerning agriculture;

viii. Medical Science: Science related to human life, disease, treatment, etc.;

ix. Genetic Engineering: Science associated with gene technology and its utilities;

x. Biochemistry: Science connected to biochemical process and diseases of organisms;

xi. Environmental Science: Science related to environment;

xii. Oceanography: Science related to the ocean and its resources;

xiii. Forestry: Science related to forest, management and conservation of its resources;

xiv. Biotechnology: Science associated with the technology of utilizing of organisms for the benefit of mankind;

xv. Pharmacy: Science dealing with technology and industry of medicine;

xvi. Wildlife: Science related to wild animals;

xvii. Bioinformatics: Biological information based on computer technology, information on the analysis of cancer, for example. On national science day, a column was published in Daily Mirror on distribution of organisms in different geographical regions and on sea animals respectively. The first one was on Bio-geography and the second one was on Oceanography.
