*Genetic code

*Composed of cells

*Organized

*Reproduction

*Growth & Development

*Use Energy & materials

*Adapt & Respond to the environment

*Change over long periods of time as a group (Evolve)

*Maintain homeostasis

65-68) What is the difference between growth and development? Give an example of each.

*Growth is when structures get larger

EX: A flower growing larger

*Development is when structures are changing or differentiating

EX: A tadpole developing into a frog

A caterpillar developing into a butterfly

69-72) What is the difference between adaptation and evolution?

*Adaptation takes place when an individual changes to respond to its environment.

*Evolution is when changes take place in populations (groups of organisms of the same species), over multiple generations. Evolution is genetically based.

73-77)Make a case for whether a computer is living OR NOT using at least 2 characteristics of life.

Short Answer:

78-81) What is the difference between eukaryotic and prokaryotic cell?

*Eukaryotic cells contain nuclei and other membrane bound organelles, while prokaryotic cells do not.

82-85) Choose 2 tenets of the nature of science, and give specific examples of each.

*Science is collaborative( Watson & Crick

*Science is creative( Rutherford’s experimental set-up and analysis

*Science is subject to change( After the structure of DNA was discovered the

field of biology and understanding of inheritance changed dramatically.

*There is no one scientific method( Fleming (by chance)

*Science is affected by perceptual frameworks( Fleming was driven by his

experiences in WWI

*Science is affected by society and vice versa( The change in beliefs about the

origins of living things were slow to change due to religious/cultural

beliefs

*Science is based on both observation and inference( Redi observed presence or

absence of flies on meat & inferred that flies only come from other flies

(& not spontaneous generation)

Bonus questions:

1) Is a picometer a very small or a very large unit of measurement?

Very small

2) What chromosomes does a human female have?

XX

3) What molecule does DNA code for? (This is how DNA controls the traits of organisms.

Proteins

4) What is the largest species of beetle found in North America?

Hercules beetle

5) What is sexual dimorphism? Give an example.

When the sexes in a species have different physical features

EX: Crab species have a giant claw

6) Where is DNA in cells? Be specific to prokaryotic and eukaryotic cells.

Prokaryotic cells—floating in the cytoplasm

Eukaryotic cells—in the nucleus

7) Fleming discovered Penicillin by observing penicillin killing bacteria on a dirty

Petri dish

8) Watson & Crick by building models in 1953

9) Rosalind Franklin took a picture of the DNA with x-ray crystallography which

helped Watson & Crick to make their discovery

10) The cultural and religious beliefs at the time were consistent with spontaneous

generation
