Is There A Scientific Dictionary

Biology Definition

This dictionary provides scientists, science writers, and all who work in scientific publishing with a clear style guide for the presentation of scientific information. In over 9,700 entries, it reflects widely accepted usage and follows the recommendations of international scientific bodies such as IUPAC and IUPAP.

What Happens When We Degrade

To degrade is defined as to treat someone with disrespect, to lower someones rank, to make something not as good, or to break down or deteriorate. When you talk down to someone and insult him, this is an example of a time when you degrade the person. To lower in quality or value make inferior or less valuable.

Where Do Biology Graduates Work

Biology graduates can hold a wide range of jobs, some of which may require additional education. A person with a degree in biology could work in agriculture, health care, biotechnology, education, environmental conservation, research, forensic science, policy, science communication, and many other areas.

biology, study of living things and their vital processes. The field deals with all the physicochemical aspects of life. The modern tendency toward cross-disciplinary research and the unification of scientific knowledge and investigation from different fields has resulted in significant overlap of the field of biology with other scientific disciplines. Modern principles of other fieldschemistry, medicine, and physics, for exampleare integrated with those of biology in areas such as biochemistry, biomedicine, and biophysics.

Biology is subdivided into separate branches for convenience of study, though all the subdivisions are interrelated by basic principles. Thus, while it is custom to separate the study of plants from that of animals , and the study of the structure of organisms from that of function , all living things share in common certain biological phenomenafor example, various means of reproduction, cell division, and the transmission of genetic material.

Animal Form And Function

Biology form 4(Chap 1 (1)

The cells in each animal body are bathed in interstitial fluid, which make up the cell’s environment. This fluid and all its characteristics can be described as the animal’s internal environment, which is in contrast to the external environment that encompasses the animal’s outside world. Animals can be classified as either regulators or conformers. Animals such as mammals and birds are regulators as they are able to maintain a constant internal environment such as body temperature despite their environments changing. These animals are also described as homeotherms as they exhibit thermoregulation by keeping their internal body temperature constant. In contrast, animals such as fishes and frogs are conformers as they adapt their internal environment to match their external environments. These animals are also described as poikilotherms or ectotherms as they allow their body temperatures to match their external environments. In terms of energy, regulation is more costly than conformity as an animal expands more energy to maintain a constant internal environment such as increasing its basal metabolic rate, which is the rate of energy consumption. Similarly, homeothermy is more costly than poikilothermy. Homeostasis is the stability of an animal’s internal environment, which is maintained by negative feedback loops.

The Basic Principles Of Modern Biology

Four principles unify modern biology, according to the book “Managing Science” :

  • Cell theory is the principle that all living things are made of fundamental units called cells, and all cells come from preexisting cells.
  • Gene theory is the principle that all living things have DNA, molecules that code the structures and functions of cells and get passed to offspring.
  • Homeostasis is the principle that all living things maintain a state of balance that enables organisms to survive in their environment.
  • Evolution is the principle that describes how all living things can change to have traits that enable them to survive better in their environments. These traits result from random mutations in the organism’s genes that are “selected” via a process called natural selection. During natural selection, organisms that have traits better-suited for their environment have higher rates of survival, and then pass those traits to their offspring.

    Basic Principles Of Biology

    The foundation of biology as it exists today is based on five basic principles. They are the cell theory, gene theory, evolution, homeostasis, and laws of thermodynamics.

    • Cell Theory: all living organisms are composed of cells. The cell is the basic unit of life.
    • Gene Theory: traits are inherited through gene transmission. Genes are located on chromosomes and consist of DNA.
    • Evolution: any genetic change in a population that is inherited over several generations. These changes may be small or large, noticeable or not so noticeable.
    • Homeostasis: ability to maintain a constant internal environment in response to environmental changes.
    • Thermodynamics: energy is constant and energy transformation is not completely efficient.

    Subdiciplines of BiologyThe field of biology is very broad in scope and can be divided into several disciplines. In the most general sense, these disciplines are categorized based on the type of organism studied. For example, zoology deals with animal studies, botany deals with plant studies, and microbiology is the study of microorganisms. These fields of study can be broken down further into several specialized sub-disciplines. Some of which include anatomy, cell biology, genetics, and physiology.

    What Is Biology At Ntnu

    Introduction to Biology | What is Biology | Science | Letstute

    The word biology is derived from the greek words /bios/ meaning /life/ and /logos/ meaning /study/ and is defined as the science of life and living organisms. An organism is a living entity consisting of one cell e.g. bacteria, or several cells e.g. animals, plants and fungi.

    Aspects of biological science range from the study of molecular mechanisms in cells, to the classification and behaviour of organisms, how species evolve and interaction between ecosystems.

    Biology often overlaps with other sciences for example, biochemistry and toxicology with biology, chemistry, and medicine biophysics with biology and physics stratigraphy with biology and geography astrobiology with biology and astronomy. Social sciences such as geography, philosophy, psychology and sociology can also interact with biology, for example, in administration of biological resources, developmental biology, biogeography, evolutionary psychology and ethics.

    What Does Identical Mean In Biology

    identical – Medical Definition


    Thereof, what does the word identical?

    Also called: quantitatively identical exactly alike, equal, or agreeing. designating either or both of a pair of twins of the same sex who developed from a single fertilized ovum that split into twoCompare fraternal (def.

    Likewise, what is the root word of identical? Great mind may think alike, but they’ll never be identical. Twins, on the other hand, very well may be if they’ve come from the same split embryo that is. It makes sense then, that the word identical has linguistic roots in the Latin word idem, meaning “the same.”

    Similarly one may ask, does identical mean exactly the same?

    Similar and identicalWe use similar if two or more things are not entirely the same, or identical if two or more things are exactly the same. We use the patterns similar to and identical to, a similar + noun or a similar + one and an identical + noun or an identical + one.

    How do you define identical twins?

    identical twinone of a pair of twins who develop from a single fertilized ovum and therefore have the same genotype, are of the same sex, and usually resemble each other closely.

    Origin Of The Term Biology

    Before the term biology was adapted, other terms existed which described the study of plants and animals. For instance, the term Natural History was used to explain animals, plants, fungi and other lifeforms in their natural environment.

    Furthermore, it was observational rather than an experimental field of study. Hence, a person who would study natural history is termed as a natural historian or a naturalist. Other terms that came before biology included Natural Theology and Natural philosophy.

    The term Biology, in the modern sense, was introduced through the works of Michael Christoph Hanow in 1766. However, it was introduced independently four more times through the works of Thomas Beddoes , Karl Friedrich Burdach , Gottfried Reinhold Treviranus and Jean-Baptiste Lamarck .

    Bacterial Transformation In Biology: What Is The Process

    In the lab, bacterial transformation is a four-step process. The first step begins with preparing competent cells that need to be transformed. This usually involves injecting a desired bacterial strain in a liquid medium as a starter culture and then creating a larger amount of culture. The strain is then made competent through the process of heat shock or electroporation.

    Once cells are competent, they are put through another round of heat shock or electroporation in the presence of plasmid DNA. This results in the uptake of the plasmid DNA by the competent cells. The transformed cells are then cultured again to increase cell viability and efficiency of the molecular cloning process.

    Lastly, when answering what is transformation in biology transformed cells are plated with the required resources to identify and recover the desired transformants. Then these transformants are used for other processes such as protein expression, subcloning, and plasmid isolation.

    What Is Inhibition In Biology

    What Is Biology?

    4.8/5biologyinhibitbiological inhibitorinhibitorbiologicalanswer here

    Inhibit comes from the Latin inhibitus, meaning “to hold in”, “to restrain”, or “to keep”. In biology, there are various molecules whose function is to inhibit. In biology, an inhibiting molecule controls, prevents, restrains, arrests, or regulates, as in “to inhibit an action”.

    One may also ask, what are the three types of enzyme inhibition? We will discuss four types of enzyme inhibition competitive, non- competitive, uncompetitive, and suicide. Of these, the first three types are reversible.

    Also to know is, what does an inhibitor do?

    Enzyme inhibitors are molecules or compounds that bind to enzymes and result in a decrease in their activity. An inhibitor can bind to an enzyme and stop a substrate from entering the enzyme’s active site and/or prevent the enzyme from catalyzing a chemical reaction. There are two categories of inhibitors.

    What is a non competitive inhibitor in biology?

    Noncompetitive inhibition is a type of enzyme inhibition where the inhibitor reduces the activity of the enzyme and binds equally well to the enzyme whether or not it has already bound the substrate.

    What Is Transformation In Biology

    Transformation is the specific process where exogenous genetic material is directly taken up and incorporated by a cell through its cell membrane. This usually occurs when the cell is in a state of competence, which is a state where the cell can uptake exogenous material. A state of competence is typically a time-limited one caused by environmental conditions around the cell.

    It can occur naturally in the environment or laboratory conditions referred to as natural competence. It can also be artificially induced by treating laboratory cultures to make cell membranes permeable to the exogenous genetic material around them.

    Combining the knowledge of colony microbiology and transformation is a crucial part of molecular cloning and synthetic biology.

    The Many Branches Of Biology

    Although there are only four unifying principles, biology covers a broad range of topics that are broken into many disciplines and subdisciplines.

    On a high level, the different fields of biology can each be thought of as the study of one type of organism, according to “Blackie’s Dictionary of Biology” . For example, zoology is the study of animals, botany is the study of plants and microbiology is the study of microorganisms.

    Uses Of Transformation In The Lab

    If you know why colonies are important in the study of microbiology and molecular biology and the different types of colonies, you must also understand what the transformation process is used for.

    For example, molecular cloning, in which transformation plays a major part, is necessary for genome organization, recombinant protein production, creation of transgenic organisms, gene therapy, and more.

    Definition Of Transformation In Biology

    What is Biology? The Characteristics of Life.

    Transformation is an important component of molecular genetics studies into the process began in the 1920s when a physician named F.Griffith realized that Streptococcus pneumoniae could convert between being harmless and disease-causing.What is transformation in biology? The theory he had back then was that a transforming principle released by dead S.pneumoniae cells caused living cells around them to form a capsule membrane that turns the pathogen into its disease-causing form. This theory has since been expanded upon with the discovery of DNA.

    So, what is the meaning of transformation in biology? Transformation is one of the three processes where genetic material is transferred from one microbial cell to another, the other two being conjugation and archaeal DNA transfer.
