Chemistry
What are the fundamental substances that make up all chemical compounds? (Hint: about 90 occur naturally)
The elements
Organisms that lack this part of the cell are called prokaryotes.
The nucleus.
It means, species are made up of organisms that inherit better traits to survive and reproduce.
Natural selection
A tool used to predict the probability of a genetic cross.
Punnett square
The term scientists use to describe the origin of the universe.
The big bang.
The name for this fundamental particle of matter means "not cuttable".
Atom
What separates the inside of a cell from the outside.
Cell membrane.
Term meaning all organisms must produce more offspring than will survive long enough to reproduce.
Overproduction
General term for the type of cells that fuse to form a zygote.
Gametes.
Age of the universe
13.77 billion years.
The most abundant element in the universe.
Hydrogen
Process by which cells copy their genetic material and make a new nucleus in preparation for cell division.
Mitosis
The differences between individuals in a population
Variation
Having two copies of every chromosome in a genome.
Diploid
Newton's 2nd Law of Motion
f=ma
or the acceleration of an object depends on the net force acting on the object and the objects mass.
Because of this principle, the mass of reactants must equal the mass of products in any reaction.
Conservation of Matter
Small organelles that decode RNA to produce proteins.
Ribosomes
The cause of genetic variation.
Mutations
The probability of two heterozygous parents producing an offspring with a recessive phenotype.
25%
A star and all the planets, moons, asteroids, comets. and other smaller bodies that orbit it.
A solar system
Has a definite volume but not a definite shape
Liquid
The network of passages that serves to transport materials through the cell.
Endoplasmic Reticulum
Variation, Inheritance, Selection, Time, Adaptation
A gene is a section of ____________ that contains the instructions for making a particular type of ______________.
DNA, protein
Currents in the mantle that are responsible for the movement of the plates of the Earth's crust
Convection currents
