A Biologist Explains: What Is Life
Is Mimivirus alive?
CC BY 4.0
Although biology is the study of life, even biologists don’t agree on what ‘life’ actually is. While scientists have proposed hundreds of ways to define it, none have been widely accepted. And for the general public, a dictionary won’t help because definitions will use terms like organisms or animals and plants — synonyms or examples of life — which sends you round in circles.
Instead of defining the word, textbooks will describe life with a list of half a dozen features based on what it has or what it does. For what life has, one feature is the cell, a compartment to contain biochemical processes. Cells are often listed because of the influential cell theory developed in 1837-1838, which states that all living things are composed of cells, and the cell is the basic unit of life. From single-celled bacteria to the trillions of cells that make up a human body, it does seem as though all life has compartments.
A list of features will also mention what life does — processes like growth, reproduction, ability to adapt and metabolism . Such views are echoed by experts such as biochemist Daniel Koshland, who listed his seven pillars of life as program, improvization, compartmentalization, energy, regeneration, adaptability and seclusion.

Monod’s Chance & Necessity And The Origin Of Life
In Chance and Necessity: Essay on the Natural Philosophyof Modern Biology, Jacques Monod argued that the discoveries of molecular biologythoroughly vindicate Darwin by providing the mechanism of heredity that was the majorknowledge gap in his theory . In hisessay Monod chastised biologists who dont concede that organisms do in factact purposefully , wherein lies a flagrantepistemological contradiction that Monod sees as the central problem of biology. Whataccounts for the purposefulness of organisms, according to Monod, is the naturally selectedhereditary mechanism that Darwin was not privy tothe inherited information encoded in the nucleotide sequence of DNA, which in the context of a living cell not onlyspecifies the functional structure of proteins , but also the information needed fortheir appropriate deployment under the range of circumstances that a cell normallyencounters. Monod pointed out that this information was completely arbitrary with respect tothe laws of physics and chemistry, and therefore was not predictable from those laws. Inother words, biology, unlike physics and chemistry, is a special scienceconcerned with functional information, i.e. information that is useful toorganisms, and hence contextually meaningful. Monod, following Ernst Mayr, refers to this asteleonomy.

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.
Within those broader fields, many biologists specialize in researching a specific topic or problem. For example, a scientist may study behavior of a certain fish species, while another scientist may research the neurological and chemical mechanisms behind the behavior.

Practices Of Science: The Language Of Science
At first glance, the language of science has lots of long words that look foreign and unfamiliar. But a closer look at scientific language can reveal that many long words are made of smaller, recognizable parts. And although they come from foreign languagesGreek and Latin for the most partthe words are more familiar than a first glance might reveal.
Lets look at an example word, biology.
Biology can be broken into two parts, or morphemes: bio– and –logy.
The morpheme bio– refers to life, and the morpheme –logy refers to the study of something. So, taken together, the word biology refers to the study of life.
These morphemes can be combined with other morphemes to create new words. Below are some words that use the morphemes bio– and logy. Check out the list of words you made using these two morphemes:
What do these words mean? Use the grid of morphemes below to understand the words.

What does the word morpheme mean? Work with a group to come up with a definition for this word.
Most words that refer to science concepts come from Latin. Some of the Latin words originally came from Greek or from Arabic, but it is the more modern Latin forms that we use today. Science words tend to stay in Latin regardless of what language is used. For example, this text is written in English, but even if it was written in Spanish, the science words would stay the same because they are in Latin.

What Does Terf Usually Stand For
According to Trans Advocate, the acronym TERF stands for trans-exclusionary radical feminist. Trans-exclusionary radical feminists are people who do not believe that trans women are real women. These people believe that the interests of cisgender women and the interests of transgender women do not intersect and that trans women should not be afforded the same validity as those born in a female body.
TERFs assert that people born male and identify as women do not have the same experience as a cisgender woman. They infer that trans women are not real women by this logic. While it is true that people who are transgender and people who are cisgender have different life experiences, this does not justify discrimination towards transgender women.
People who believe trans women are not real women also think that the term TERF is a slur and that anyone who uses it is a misogynist. This is not the case.
Others believe that the term TERF is misleading. These people see it as a facade for transphobia under the guise of feminism and womens rights. The exclusion of a transgender person does not make a person a feminist it makes them transphobic. Therefore, the term TERF is overly generous to transphobic individuals.

False Positives And False Negatives
Choosing whether it is better to risk false positives or false negatives is not necessarily an objective process. If the issue is a new and tasty but potentially harmful artificial sweetener, extremely wary consumers might want to bias their judgment against false negatives during safety testing. That is, they may prefer to lose a good sweetener than to mistakenly accept as safe one with harmful side effects. However, the company marketing the sweetener may feel otherwise. The company has more to lose with a false negative and may want a more even balance between the likelihood of false negatives and false positives. A less scrupulous company may want to bias the judgment against false positives. Consumers who are more concerned with preventing weight gain than with ensuring their health may likewise want a bias against false positives.
By contrast, the third definition of lifeas evolution by natural selectiondoes not yield a high rate of false positives. No known abiotic agent could ever give patterns similar or analogous to those in and . Based on our knowledge of terrestrial chemistry and biology, the ability to change and improve in the manner predicted in the figures can be the result only of evolution by natural selection. And, on Earth, evolution by natural selection is the exclusive characteristic of life. On this basis, false positives are not possible if the definition of life is evolution by natural selection.

What Is Biology At Ntnu
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.
