Define unicellular and give an example

What is a living thing that consists of a single cell. Bacteria and protists.

100

Define growth and give an example

What is a change in size. Getting taller

100

Define: stimulus

What is anything that cause a reaction. A signal to which an organism responds.

100
Define evolution
What is change in a species over a great amount of time.
100
What is biology?
What is the study of life
200

Define multicellular and give an example.

What is an organism with more than one cell. Human, dog, cat, fish, frog, etc

200

Where does an organism get their traits?

What is from their parents

200
Define metabolism
What is the combination of chemical reactions by which an organism builds up or breaks down material
200
Give an example of an adaptation
What is desert plants, desert animals, fur on polar animals, coloring of animals....
200
Define a cell
What is a collection of living matter surrounded by a barrier
300

Define reproduction

What is the process by which organisms produce new organisms.

300

Define development and give an example

What is a change in physical or physiological appearance. Caterpillar-butterfly, puberty, larvae-fly

300
Define autotroph and heterotroph and give an example of each
Autotroph: An organism that makes it's own food (Plant, algae, certain bacteria) Heterotroph: An organism that eats to obtain energy (human, dog, cat, bird, certain bacteria)
300
Define homeostasis
What is the processes by which an organism maintains a relatively stable internal environment.
300
Explain the difference between an observation and an inference
An observation is the gathering of information using the 5 senses. An inference is a logical interpretation based on prior knowledge
400

Define budding

What is a type of asexual reproduction where the offspring "buds" or grows off the parent, then detaches becoming a new organism.

400

Do single-celled organism grow and develop?

No, they grow in size, but do not develop

400
What are the 2 types of stimuli and give an example of each.
What is internal (body temperature, water balance, blood sugar) and external (light, temperature, sound, gravity, pressure)
400
How does a species evolve?
What is mutations. Random changes in the DNA of a species.
400
What is the independent variable?
The variable we intentionally change in an experiment.
500

Is reproduction essential to the survival of the species or the individual and why?

The survival of the species. A species as a whole must be able to reproduce, but each individual organism does not need to reproduce to survive.

500

Explain how the offspring of asexual reproduction and the offspring of sexual reproduction differ and why.

Offspring of asexual reproduction are clones (genetically identical) to their parents. Offspring of sexual reproduction differ from their parents because they have a combination of genetic material from both.

500
Identify and explain the 2 ways we discussed that autotrophs use to obtain energy. Which one is more common?
What is Photosynthesis: Using sunlight energy to make food* Chemosynthesis: Using chemical energy to make food
500
Define thermoregulation and explain the processes your body goes through to maintain it.
What is the regulation of body temperature. When our temperature is too high we sweat to cool down. When our temperature is too low we shiver to warm up.
500
Define specialization and give an example
Cells that have a particular function or job within a multicellular organism. Brain cells, nerve cells, muscle cells....
