an attraction between two atoms, resulting from a sharing of outer - shell electrons or the presence of opposite charges on the atoms; bonded atoms receive complete outer electron shells
What is a CHEMICAL BOND
100
cell's genetic material
What is DNA
100
substance that cannot be broken down to other substances by chemical reactions
What is ELEMENT
100
a macromolecule serving as a catalyst, a chemical agent that increases the rate of a reaction without being consumed by the reaction; most are proteins
What is ENZYMES
100
the third phase of mitosis, in which the spindle is complete and the chromosomes, attached to microtubules at their kinetochores, are all aligned at the metaphase plate
What is METAPHASE
200
a type of strong chemical bond in which two atoms share one or more pairs of valence electrons
What is COVALENT BOND
200
units of inherence that transmit information from parents to offspring
What is GENES
200
smallest unit of matter that still reins the properties of an element
What is an ATOM
200
any group of large biological molecules, including fats, phospholipids, and steroids, mix poorly with water
What is LIPIDS
200
the first stage of mitosis; chromatin condenses into discrete chromosome visible with a light microscope; nucleus remains intact
What is PROPHASE
300
a chemical bond resulting from the attraction between oppositely charged ions
What is an IONIC BOND
300
diverse and widespread prokaryotes and are classified in multiple kingdoms; rod shaped structure
What is BACTERIA
300
a subatomic particle with a single positive electrical charge; found in the nucleus of an atom
What is PROTONS
300
a carboxylic acid with a long carbon chain. Fatty acids vary in length and in the number and location of double bonds three form a fat molecule known as a triglyceride
What is FATTY ACID
300
the fifth and final stage of mitosis, in which daughter nuclei are forming and cytokinesis has typically begun
What is TELOPHASE
400
a covalent bond between atoms that differ in electronegativity; positive and negative get pulled together
What is a POLAR COVALENT BOND
400
live in Earth's extreme environments; multiple kingdoms; prokaryotes; round structure
What is ARCHAEA
400
a subatomic particle with a single negative electrical charge; one or more electrons move around the nucleus of an atom
What is ELECTRON
400
the second stage of mitosis in which the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the chromosomes
What is PROMETAPHASE
500
the linking together of like molecules, often by hydrogen bonds
What is COHESION
500
organisms that contain eukaryotic cells; includes these 3 kingdoms Plantae (land plants), Fungi (mushrooms), Animalia (ingest other organisms)
What is EUKARYA
500
the number of grams of a substance that equals its molecular weight in daltons and contains Avogadro's number of molecules
What is MOLE
500
one of two compounds that are mirror images of each other and that differ in shape due to the presence of an asymmetric carbon
What is ENANTIOMERS
500
the fourth stage of mitosis, in which the chromatids of each chromosome have separated and the daughter chromosomes are moving to the poles of the cell
