How did Lamarck explain changes in organisms? He hypothesized that acquired traits arise during an organisms lifetime as a result of the organism's experience or behavior How did Charles Darwin explain changes in organisms? He reasoned that the environment limits the growth of the population by in...

Adhesion and cohesion The representation of H - O - H is known as: a structural formula A substance that is composed of only one ...

Two main ideas contained in the cell theory -cells come from other living cells via reproduction -cells are the basic unit of structure and function for all living things The role the surface area plays in the exchange of materials between the cell and its environment for a cell: the membrane -anyt...

What are the three parts of the cell theory? Every cell is made up of one or more cells. Cells are the basic unit of structure. All cells are from pre-existing cells. How was the cell theory discovered? The cells theory was discovered by Robert Hooke when he was looking at a peice of cork under a m...

Mitochondria An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. Golgi body A structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them...

Adaption Inherited characteristic that improves an organism's ability to survive and reproduce in a particular environment Natural Selection Process by which individuals with inherited traits well-suited to the environment leave more offspring than do other individuals Descent with modification O...

To be classified as a living organism, what qualities must you possess? Metabolize, reproduce, cells, homeostasis, evolve, grow/develop, and stimuli. What is homeostasis? The ability to maintain constant or stable conditions What is the difference between growth and development? To grow is to get ...

Your bone cells, muscle cells, and skin cells look different because ___________. Different genes are active in each kind of cell. If the nucleus of a frog egg is destroyed and replaced with the nucleus of an intestine cell from a tadpole the egg can develop into a normal tadpole. This demonstrates...

Explain why the kingdom Protista is a "catch-all" kingdom. -Protists have a far greater degree of diversity than any other eukaryotic kingdom. -They are not members of the plant, animal, or fungi kingdoms. -The kingdom Protista is made up of organisms that don't really belong anywhere else. Desc...
