My Scientific Glossary
My Scientific Glossary.
Hi, my name is Khadija Baccouche and I live in Laval. I have been studying in the Natural Sciences program for over a year, specifically in science, at Montmorency College. College comes after studying 6 years of primary school and 5 years of secondary school. This glossary is for people who want to learn some words from this program in English, so it may be useful for people who are already in this program, as well as people who want to enroll in it. Each of these words is related to one of the main subjects of this program, and each definition was taken from Google.

- Example: All the body systems create the human.
- fr: système corporel
- catalyst
- noun
- A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
- Example: Although true empowerment must come from within, organisations, like a CATALYST, play a crucial role in this process.
- fr: catalyseur
- cell
- noun
- The smallest structural and functional unit of an organism, typically microscopic.
- Example: Mitochondria are among the larger organelles in the CELL.
- fr: cellule
- chemical reaction
- noun
- A process where existing chemical substances, called reactants, are transformed into new substances, called products, by rearranging their atoms and breaking and forming chemical bonds.
- Example: One possible way to deal with this problem is to control the motion of molecular in CHEMICAL REACTION.
- fr: réaction chimique
- chemistry
- noun
- The branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
- Example: Advances in agricultural CHEMISTRY caused many farmers to simplify their rotations.
- fr: chimie
- deoxyribonucleic acid (DNA)
- noun
- The molecule that carries genetic instructions for the development, functioning, and reproduction of all known living organisms.
- Example: In the nucleus, DNA is associated with proteins called histones.
- fr: acide désoxyribonucléique (ADN)

- electron
- noun
- A stable particle with a charge of negative electricity, found in all atoms.
- Example: This ELECTRON transport chain is much simpler compared to that of the ammonia oxidizing bacteria.
- fr: électron
- energy
- noun
- Power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.
- Example: They take electrons from food molecules extract the ENERGY and combine them to oxygen and protons.
- fr: énergie
- enzyme
- noun
- A substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.
- Example: This is done by the action of an ENZYME.
- fr: enzyme
- equation
- noun
- A symbolic representation of the changes which occur in a chemical reaction, expressed in terms of the formulae of the molecules or other species involved.
- Example: The restricted model is represented by EQUATION.
- fr: équation

- evolution
- noun
- The process by which animals, plants, and other living organisms are transformed into different forms by the accumulation of changes over successive generations.
- Example: A hypothesis to explain the role of meat-eating in human EVOLUTION.
- fr: évolution
- histogram
- noun
- A diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval.
- Example: HISTOGRAM of Log Returns.
- fr: histogramme
- molecule
- noun
- A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
- Example: The protein complex loads onto the end of a DNA MOLECULE, as it travels along it produced two loops.
- fr: molécule
- organism
- noun
- An individual animal, plant, or single-celled life form.
