Q

Includes both the living and no living components of an area (adding water to the mix)

A

Ecosystem

Q

Refers to all parts of the planet that can support life

A

Biosphere

Q

Chemistry of living cells

A

Metabolism

Q

Constant stream of energy required to maintain organized life

A

Metabolism

Q

3 purposes of metabolism

A

1) build new structures
2) repair old ones
3) reproduce

Q

True/False: photosynthesis and cellular respiration are examples of energy use

A

True

Q

Extract energy and nutrients from non-living environment

A

Producer/autotrophs

Eat other organisms, living or dead, for nutrients

Consumer/heterotrophs

Obtain energy from wastes or dead organisms

Decomposer

Plants and some microbes are examples of which part of the energy flow?

Producer/autotrophs

Fungi and many bacteria are examples of which part of the energy flow?

Decomposed

Humans and other animals are examples of which part of the energy flow?

Consumer/heterotrophs

State of internal constancy or equilibrium | Ex. Shivering, vasoconstriction/dilation

Homeostasis

Homeostasis of internal body temp

37 degrees C | 98.6 degrees F

Disease is

A disruption of homeostasis

Is mitosis sexual or asexual

Asexual

Is meiosis sexual or asexual

Sexual

Asexual or Sexual: Organism produces all offspring identical to itself

Asexual

Asexual or sexual: Genetic material from 2 parent individual unites to form an offspring, which had a new combinations of inherited traits

Sexual

Mitosis or Meiosis: Allows variety and diversity and is an evolutionary advantage

Meiosis

Which must have multicellular? Mitosis or Meiosis

Meiosis

A change in the genetic makeup of a population over multiple generations

Evolution

True/False: some organisms can reproduce either way depending on conditions

True

What term defines that some organisms seem "perfectly" adapted to their environment

Evolution
