Q

What are two binary fission examples?

A
  1. Bacteria Fission- one cell multiplies its DNA and size then splits into two identical cells (Prokaryotic)
  2. Amoeba Fission- one cell multiplies its DNA and size then splits into two identical cells (Eukaryotic)

19
Q
  1. NEED FOOD & ENERGY

What are the two types of feeders?

A

Autotrophs and Heterotrophs

20
Q

a.) What is a Autotroph?

b.) What is a Heterotroph?

A

a.) They make their own food using photosynthesis- using light to make glucose

b.) The can’t make their own food so they rely on other organism for energy

21
Q

What is the equation for photosynthesis?

A

light+C6H12O6=====> C6H12O6+6CO2

22
Q

What are the two types of heterotrophs?

A
  1. Consumers- ingest and digest food
  2. Decomposers- absorb nutrients
23
Q

What are the three types of consumers?

A
  1. Carnivores- meat eaters
  2. Herbivores- plant eaters
  3. Omnivores- plant and meat eaters
24
Q

a.) What is cellular respiration?

b.) What is the equation for cellular respiration?

A

a.) Using energy

b.) C6H12O2====>H2O+CO2+ATP

25
Q
  1. HOMEOSTASIS

a.) What is homeostasis?

b.) What is an example?

A

a.) To maintain balance in the body

b.) Body temp- sweat to cool down + shiver to heat up

26
Q
  1. RESPOND TO THE ENVIRONMENT

a.) What does respond to the environment mean?

b.) What are two examples?

A

a.) To react to the environment

b.) 1. Fight or Flight
2. Plants grow toward light

27
Q
  1. ADAPT TO THE ENVIRONMENT

a.) What does adapt mean?

b.) What is an example?

A

a. To change (increase chance of survival) because DNA changes

b. Polar bears- have lost of blubber, look white to blend in

27
Q
  1. MADE UP OF CELLS THAT CONTAIN DNA

a.) What are cells?

b.) What is DNA?

A

a.) The building blocks of life
