Change in Velocity / Time Taken
what is Acceleration
Energy that travels across distances in the form of certain types of waves.
Type of genotype in which an individual has 2 of the same allele for a gene
what is Homozygous
A membrane bound structure that is the basic unit of life
body system the breaks down food and absorbs nutrients. Includes: mouth, esophagus, stomach, small and large intestines.
what is Digestive System
Mass x Acceleration
A layer in the stratosphere (at approximately 20 miles) that contains a concentration of ozone sufficient to block most ultraviolet radiation from the sun.
Type of genotype in which an individual has 2 different alleles for a gene
what is Heterozygous
The lipid bilayer that forms the outer boundary of the cell
the body's system of defense against disease.
what is Immune System
Force / Area
An instrument that measures air pressure in the atmosphere.
The weaker version of a gene. The form that is masked if a dominant one is present
what is Recessive
This says that 1. all living things are made of cells, 2. cells are the basic unit of structure and function and 3. cells only come from other cells.
The system that delivers oxygen and nutrients and removes carbon dioxide and wastes from the body by the blood. Includes the heart and blood vessels.
what is Circulatory System
Mass x Gravity
A process by which a substance changes from its liquid state to its gas state by random particle movement.
The stronger version of a gene. The form that will show up if present
what is Dominant
A rigid structure that surrounds the cells of plants and most bacteria
The system that removes wastes from the body.
what is Excretory System
Useful Energy Output / Total Energy Input
The influence of Eath's rotation on objects that move over Earth.
Combination of alleles (2) that an individual inherits for a specific gene
The region of the cell between the cell membrane and the nucleus
