Micronutrients are nutrients needed throughout life in small quantities
a chemical element required only in minute amounts by living organisms for normal growth.
the basic unit of a chemical element.
The atom is a basic unit of matter that consists of a dense, central
nucleus surrounded by negatively charged electrons
the central part of any object or living thing
the number of protons in the nucleus of an atom
no electric charge
the number of protons and nuetrons in and atom
Electron energy level
amount of electrons and protons are level
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons
The radioactivity breaking down the object into half its original form
a molecule with negatively charged ends
weak bond between molecules a negative to a positive atom
the chemical process to maintain life (homeostasis)
a substance that takes part and changes in a reaction
manufactured by an enzyme
a thing that is composed of two or more separate elements
a chemical bond that involves sharing a pair of electrons between atoms in a molecule
atoms bonded together
an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
positively charged ion
a negatively charged ion
A bond wiht the loss of one proton or nuetron
a mix of elememets not changing into a new thing
a mixture where they create something new
a acid that can dissolve something
minor component in a solution
a basic element that can be changed easily
carbon 14 dating
age of materials
each of two or more compounds with the same formula but a
different arrangement of atoms in the molecule and different properties.
a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded togethe
energy about to accour
basic energy made up of sugar and junky food
any class of sugar
any of a class of sugars whose molecules contain two monosaccharide residues.
the conversion of a vapor or gas to a liquid.
In chemistry and the biological sciences, a dehydration reaction is
usually defined as a chemical reaction that involves the loss of water
from the reacting molecule. Dehydration reactions are a subset of
plant cell wall
a substance deposited in bodily tissues as a store of carbohydrates
any of a class of organic compounds that are fatty acids
a colorless, sweet, viscous liquid formed as a byproduct in soap manufacture
the last form of enegy burnt
a simple organic compound containing both a carboxyl (-COOH) and an amino (-NH2) group.
the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.
he primary linkage of all protein structures
a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction.
a complex organic substance present in living cell
a compound consisting of a nucleoside linked to a phosphate group.
Nucleotides form the basic structural unit of nucleic acids such as
deoxyribonucleic acid, a self-replicating material present in nearly all living organisms
ribonucleic acid, a nucleic acid present in all living cells. Its
principal role is to act as a messenger carrying instructions from DNA
for controlling the synthesis of proteins
molecule or other entity that can donate a proton or accept an electron pair in reactions
not an acid
A system that regulates
the chemical breakdown of a compound due to reaction with water.
