scope of biology by awantika
Biology is the study of life and living organisms. It recognizes the basic units of life as the cell and gene, and the process that drives evolution and creation of new species. Biology includes many subdisciplines that study different levels of life, such as molecular, cellular, physiology, and ecology. Structural biology studies molecular structures, physiology examines how structures function as a whole, and evolutionary biology focuses on the origin and change of species over time. While biology advances human prosperity, its techniques have also been misused for biowarfare, bioterrorism, sex-selective abortion, and other harmful purposes against humanity.
Introduction to Biology
Living things have several key characteristics:
1. They are made of cells, the basic units of life.
2. They obtain and use energy. Autotrophs like plants make their own food through photosynthesis, while heterotrophs like animals consume other organisms for food.
3. They grow, develop, and reproduce. Multicellular organisms grow by adding more cells through mitosis and development, while both unicellular and multicellular organisms reproduce sexually or asexually.

Introduction to Biology
Biology is the study of life. It began with early Greek philosophers who began classifying living things. Important figures like Aristotle, Galen, and Andreas Vesalius made advances in anatomy and classification. William Harvey discovered blood circulation. The development of the microscope allowed Anton van Leeuwenhoek to discover microorganisms. Charles Darwin developed the theory of evolution by natural selection. The major divisions of biology are botany, which is the study of plants, and zoology, which is the study of animals. Key areas of biology include anatomy, physiology, ecology, taxonomy, embryology, genetics, and microbiology.

Secondary biology; Introduction to Biology
Biology is the study of living things and is divided into several branches including zoology, botany, and microbiology. It involves studying the characteristics of living things such as nutrition, respiration, reproduction, growth, and response to stimuli. Classification systems group organisms based on similarities, with taxonomy being the science of classification. The main taxonomic units are domain, kingdom, phylum/division, class, order, family, genus, and species. Classification is important for identification, understanding evolutionary relationships, and arranging biological information.
General biology
Biology is the science of life and living organisms, including their structure, function, growth, origin, and distribution. It includes subdisciplines like microbiology, botany, zoology, anatomy, physiology, cell biology, biochemistry, genetics, and molecular biology. Biology seeks to understand life at different scales, from molecules to cells to tissues to whole organisms, and examines the chemistry and physics underlying living things. Key concepts that guide biologists include different levels of biological organization and the idea that the difference between living and non-living things is one of degree rather than kind.
Branches Of Biology2008 2009

This document provides an overview of the key characteristics of life, including organization, acquiring materials and energy, reproduction, response to stimuli, homeostasis, growth and development, and adaptation. It also discusses the classification of living things into domains, kingdoms, and species. Finally, it covers the organization of the biosphere into populations, communities, ecosystems, and the human impact on biodiversity.
Speciation
Speciation is the process by which new species form. It occurs when populations become isolated from each other and diverge to the point that they can no longer interbreed. Isolation can be geographic, such as when physical barriers separate populations, or reproductive, such as when changes prevent successful mating. Speciation rates may be gradual over millions of years or punctuated by rapid changes following events like natural disasters. The evolutionary history and relationships between species can be modeled in cladograms or phylogenetic trees.
Evolution of populations
This document discusses population genetics and microevolution. It explains that evolution occurs at the genetic level through heritable changes in DNA, arising from various sources of genetic variation within populations like mutation, recombination, and random mating. The key concepts of gene pool, allele frequencies, genetic equilibrium, and Hardy-Weinberg principle are introduced to illustrate how evolution can result from changes in the distribution of alleles in a population over generations under the influence of genetic drift or natural selection.

Patterns of heredity and human genetics
This document discusses several patterns of human genetics and heredity, including simple dominant and incomplete dominant inheritance. It provides examples of traits that follow each pattern, such as tongue rolling being a simple dominant trait and flower color in plants being an example of incomplete dominance. The document also covers codominance, polygenic inheritance, sex determination and sex-linked traits such as hemophilia. It explains how traits can be influenced by sex hormones in some cases.
Dna to chromosomes
The document discusses how eukaryotic cells package DNA into chromatin and chromosomes. DNA is found in the form of chromatin during interphase, which involves tightly coiling DNA around histone proteins to form nucleosomes. Nucleosomes are the basic unit of DNA packaging, allowing the 2 meters of DNA in human cells to fit inside the nucleus. Chromosomes only form when cells are preparing to divide and reproduce, allowing DNA to be passed from parent cells to daughter cells.
Species interactions comm ecology
This document summarizes the five major types of species interactions: predation, competition, parasitism, mutualism, and commensalism. It defines each interaction and provides examples. Predation involves one species consuming another for food, while competition occurs when two species require the same limited resources. Parasitism benefits one species at the expense of the other. Mutualism is a cooperative relationship that benefits both species, such as pollination. In commensalism, one species benefits while the other is not affected.
The biosphere
The document summarizes the key spheres that make up Earth's biosphere - the geosphere, hydrosphere, atmosphere, and anthrosphere. It then discusses Biosphere 2, an artificial closed ecosystem experiment in Arizona meant to study interactions within a biosphere. The experiment identified issues like too much CO2 and not enough O2 or food production. It also summarizes the major biogeochemical cycles of water, carbon, nitrogen, and phosphorus that are vital to life on Earth.
Ecological succession
Ecological succession is the gradual replacement of one community by another over time. It is initiated by disturbances that remove existing organisms or alter resources and habitat. There are two types of succession: primary succession occurs in areas without soil, while secondary succession occurs in areas with existing soil following a disturbance. In both cases, pioneer species are the first to colonize, and succession progresses gradually until an equilibrium climax community dominated by less tolerant species is reached if undisturbed.
Unique properties of water
Water is a polar molecule that is essential for life. Its polarity allows it to dissolve many other polar substances and act as a solvent for biological molecules and reactions in living cells and organisms. Water has unique physical properties, such as a high heat capacity and ability to form hydrogen bonds, that make it well-suited to regulate temperature and support life processes on Earth. The polarity and hydrogen bonding of water molecules also allow water to have high surface tension and influence many other physical phenomena.
Cells of the six kingdoms
There are six kingdoms that classify life on Earth - Eubacteria, Archaebacteria, Protista, Fungi, Plantae, and Animalia. Eubacteria and Archaebacteria are prokaryotic and unicellular, while Protista, Fungi, Plantae, and Animalia are eukaryotic. Protista can be unicellular or multicellular, Fungi and Plantae are multicellular, and Animalia are always multicellular. The kingdoms differ in their cell structures, body forms, and modes of nutrition, which can include photosynthesis, chemosynthesis, heterotrophic nutrition like phagocytosis, or secretion and absorption of enzymes
Cells
Cells are the basic units of life. All living things are made of cells, and cells come only from other living cells. There are two main types of cells - prokaryotic cells which lack a nucleus and membrane-bound organelles, and eukaryotic cells which have a nucleus and membrane-bound organelles. The document goes on to describe the structures and functions of various cell organelles like the nucleus, mitochondria, chloroplasts, cell membrane, and others. It also compares the differences between plant and animal cells.
Introduction to ecology 2
This document provides an introduction to ecology, including definitions of key terms and concepts. It explains that ecology is the study of the relationships between organisms and their environments. It describes the different levels of ecological organization from the biosphere down to the individual organism. It also defines biomes as large geographical areas with similar climates and ecosystems, and lists some major biomes such as tundra, taiga, and tropical rainforest. Finally, it discusses adaptations as traits that enhance an organism's survival and are maintained by natural selection.
Characteristics of life
This document outlines the 8 characteristics of living organisms: 1) unique biochemistry, 2) organization and cells, 3) response to stimulus, 4) homeostasis, 5) metabolism, 6) growth and development, 7) reproduction, and 8) adaptation and evolution. Each characteristic is defined and an example is provided to illustrate the meaning. The document explains that all living things share fundamental biochemical similarities and that cells are the basic functional units of living things.
Hierarchy of biology additional notes
The document discusses several key topics in biology including cells, tissues, organisms, populations, communities, ecosystems, biomes, and the biosphere. It explains that cells are the basic structural and functional units of all life on Earth and can be either prokaryotic or eukaryotic. Tissues, populations, and communities are discussed in the context of multicellular organisms. Ecosystems are natural systems consisting of biotic and abiotic factors in an area, while biomes represent major communities with similar environmental conditions over large geographic areas. Finally, the biosphere encompasses all global ecosystems within the zones of air, land, and water where life exists.
Methods used by biologists
Biologists use several methods to study organisms including making inferences based on observations and prior knowledge, direct observation using the five senses to detect things in experiments and record events, and both qualitative observations using words, diagrams, pictures, colors, odors and sounds as well as quantitative observations involving numerical data through measurements, calculations and graphs which must include units when reporting raw or processed data.
Introduction to HBS: Unifying Themes
Introduction to the course of Human Body Systems (and how it relates to basic anatomy and physiology)
What is biology and Why study biology?
Biology is the study of living things, life processes, habitats, interactions, history and future of life. It examines all kingdoms including animals, plants, fungi, protists, eubacteria and archaebacteria. Studying biology is important because living things are interdependent and human existence relies on other organisms. Understanding biology has allowed humans to develop agriculture, solve medical problems, and be curious about their place in the world. Continued discovery will provide knowledge to improve lives and ensure a healthy future for our planet.
Antigens and antibodies
Antigens are substances that cause the immune system to produce antibodies. Antigens can be external, like bacteria or viruses, or internal, like bacterial toxins or damaged cells. Antibodies are proteins produced by the immune system in response to antigens. Each antibody targets a specific antigen. When an antibody binds to its matching antigen, it helps protect the body or tags antigens for destruction.
Body defenses against infection
The document summarizes the body's immune defenses against infection. It describes two main types of immunity: innate immunity, which provides nonspecific defenses like skin barriers and phagocytes; and acquired (adaptive) immunity, which develops after exposure and provides pathogen-specific responses using B cells, T cells, antibodies, and immunological memory. The immune system uses successive lines of defense, from physical barriers and phagocytes to inflammation and antibodies, to protect the body. Vaccines help produce active immunity by exposing the immune system to weakened or killed pathogens.
Lymphatic system notes
The lymphatic system defends against infection and disease by returning tissue fluid to the bloodstream. It consists of lymphatic capillaries that collect fluid from tissues, terminal ends that connect to lymphatic ducts, and lymphatic ducts that return the fluid to the venous system.
Enzymes for hbs
Enzymes are proteins that act as biological catalysts and are necessary for most chemical reactions in living cells. They help reactions occur by lowering their activation energy. Enzymes have a unique three-dimensional shape with active sites that allow them to specifically bind to substrates and rearrange the molecules involved in chemical steps. While they are not consumed in these reactions, enzymes increase the rates of reactions and can be reused, making them highly efficient biological catalysts.

Editor's Notes
- Notes handout. Recommended for students to color-code their notes.
- Subatomic particles determine the type of matter and the behavior of matter. Ex: the number and arrangement of electrons determines the interaction of one atom with another.
- Molecules are made up of atoms. Biologically significant molecules: DNA Carbohydrates Proteins Lipids
- Nanotechnology is the manipulation of matter on an atomic, molecular, and supramolecular scale. Nanotech range = 1-100 nm Nanometer (nm) = one billionth of a meter (10-9) Nano – from greek for dwarf Nanotechnology in biology Molecular nanotechnolgy Nanofluids Nanomedicine Tissue engineering (tissue scaffolds) DNA nanobots = targeted drug delivery Environmental applications
- Cells of may types are the working components of living organisms.
- A tissue is a group of many cells with similar and coordinated functions.
- Organs combine several tissues that function together.
- Organs form systems.
- An organism is a recognizable, self-contained individual. A multicellular organism is made up of organs and organ systems.
- Species is the largest group of organisms where two individuals are capable of reproducing fertile offspring. A population is a group of many organisms of the same species
- Communities consist of populations of many different species
- Biological communities in the same geographical location, along with all of the nonliving components, make up an ecosystem.
- Major ecosystems that spread over a large portion of the earth and share similar abiotic and biotic factors are referred to as biomes.
- Ecosystems exchange energy and create earth’s biosphere.
- The unifying themes of biology tie biology together from the smallest level to the largest. The unifying themes of biology apply to life studied at any level on the hierarchy.
