Traits and Reproduction
Instructions for making a protein molecule
gene
Oxygen, glucose, and amino acids
a noticeably different form or state of the same substance
phase
The temperature at which a substance changes from the solid phase to the liquid phase is the ____________
melting point
Two gene copies that are the exact same
homozygous
When one parent cell duplicates and creates a cell that is exactly the same
asexual reproduction
System that accepts oxygen
respiratory system
Increase in Kinetic Energy of a substance will lead to what phase change?
melting or evaporating
During chemical reaction, atoms cannot be _______ or ________
Created or destroyed
Two gene copies that are different
heterozygous
When two different parent reproduction cells combine and make an offspring's cell
sexual reproduction
This system is made up of mouth/nose, stomach, and small intestine
What happens to the molecules of a substance as it changes phases?
molecules move differently
A process in which atoms rearrange to form a new substance
chemical reaction
A group of atoms joined together in a particular way
molecule
variation
This organelle is where cellular respiration occurs and is the power house of the cell
Mitochondria
When transferring energy out of a substance it can change the molecules ___________
Freedom of movement
Evidence that a chemical reaction has occurred is
a change to the properites
(color, smell, temp, etc.)
product
When a gene randomly changes and sometimes gives the offspring a new trait
mutation
These molecules are used by cells for growth and repair
protein or amino acids
When increasing kinetic energy of a substance, when does the phase change occur?
when enough energy is added to overcome the molecular attraction
During a chemical reaction, what happens to the atoms?
ALL of the atoms that make up the reactants rearrange to form the products
independent variable
