levels in biological systems beginning with atoms/molecules and increasing in complexity. 

What is regulation (homeostasis) in the essential characteristics of life?

keeping internal conditions stable. 

What is reproduction in the essential characteristics of life?

pass along traits from one generation to the next. 

What is energy processing (metabolism) in the essential characteristics of life?

energy is required for all life processes.

What is the response to the environment in the essential characteristics of life?

reacts to changes in the internal or external environment.

What are growth and development in the essential characteristics of life?

1. Explain the difference between prokaryotic and eukaryotic cells.

Prokaryotic- a cell that does not have a nucleus.

Eukaryotic- a cell with a nucleus (surrounded by its own membrane) and other organelles.

1. Explain the difference between unicellular and multicellular organisms.

Unicellular- made of a single cell.

Multicellular- made of multiple cells.

Describe the levels of organization present in living organisms.

Explain the difference between asexual reproduction and sexual reproduction.

Asexual- process of reproduction involving a single parent that results in genetically identical offspring.

Sexual- process of reproduction involving two parents that combine genetic material to produce an offspring. 

1. Describe how negative feedback loops maintain homeostasis within organisms. 

1. Explain the difference between autotrophs and heterotrophs.

Autotrophs- organism that makes its own food.

Heterotrophs- organism that obtains energy from the food it consumes.
