Bio 103 Test 1

Front 1

Be prepared to recognize true and false statements regarding the nature of science (for example, saying that science is the only way to understand the universe would be false while saying that science produces models of the physical universe would be true)

Back 1

Science is an open system of skeptical inquiry producing falsifiable knowledge subject to modification based on empirical and objective testing.

It is open & always changing.

Front 2

empiricism

Back 2

making observation using the 5 senses

Front 3

objectivity

Back 3

trying to reduce bias

Front 4

quantification

Back 4

using numbers or measuring

Front 5

precision

Back 5

getting same results consistantly

Front 6

accuracy

Back 6

getting right or acceptable answer

Front 7

reductionis,

Back 7

summarizing info by making table or graph

Front 8

skepticism

Back 8

challenging you ideas and even others.

Front 9

no absolutes

Back 9

open to change

Front 10

scientific method

Back 10

solving through observation, questioning, hypothesis (testable & open to be falsified), testing, analyzing and interpreting, conclusding, new questions hypthosis and results published for verification

Front 11

inductive reasoning

Back 11

bottom-up specific to general

Front 12

deduction

Back 12

top down general to specific

Front 13

Pseudoscience

Back 13

a claim, belief, or practice which is presented as scientific

Front 14

frontier science

Back 14

underdeveloped or new science. not much research

Front 15

From a scientific perspective, what's are the problems with using personal experience, intuition, authority or dictionary definitions to define "life?"

Back 15

personal experience: no data
dictionary: vague
intitution: no data
authority: no data

Front 16

What's an operational definition and what are its advantages to a scientific definition of life?

Back 16

-needs to construct a list of characteristics of life. They must be open to objective, empirical, and verification.

Front 17

Why is a list of characteristics of life a guideline to establishing that something is or was alive versus an all-or-nothing definitive definition?

Back 17

It is objective, empirical, and can be verified

Front 18

Understand the different ways that biologists approach the study of life such as choosing an organism to investigate or a level of organization to focus on

Back 18

type of organism (botany, zoology..orhithology, ichthyology, herpetology)
2) based on organization level (molecular, cellular, organismic)
3) study based on function or structure (anatomy, evolution, behavior)
*or combination

Front 19

What were the ancient Greek and Indian paradigms of matter and what is the current chemical paradigm? How are they similar and how are they different?

Back 19

Greek & Indian models proposed smallest particle of matter atom. Matter is composed of limited number of building block elemets. (Fire/Water/Air/Eath)

Current: atomic theory. Matter made of limited number of element. Elements made of atoms unique to them. 92 natural elmests. Atoms bond to make molecules.

Front 20

Paradigm shift

Back 20

change in basic assumptions within the ruling theory of science

Front 21

Could you state the law of conservation of matter in your words or recognize an example of it?

Back 21

Matter isn't created nor destryoed. Just rearranged.

Front 22

Know the properties of carbon and the resulting consequences to life

Back 22

Stable in water-doesnt decompose in water

2)small-more stable

3) each atom is capable of forming 4 bonds (backbone for bio molecules)

Front 23

Know the properties of water and the resulting consequences to life

Back 23

1)interacts w/ many molecules
2)excellent solvent- carries waste/delivers nutriets
3) transparent- can see and let sun penetrate through

Front 24

What are the four major types of biological molecules and, for each type, how is it constructed and what are the primary functions?

Back 24

lipids-fat
proteins-amino acids fuction as enzymes
carbohydrates-simple sugar function as energy
nuclear acid (DNA)-function inheritance

Front 25

For photosynthesis, be familiar with the following:

What is its basic function?
What enters and leaves the process in terms of matter and energy?
What happens (in general) in the light-dependent and light-independent parts of the process?
How does it obey the law of conservation of matter conservation?
How does it obey the laws of thermodynamics?

Back 25

Production of glucose from CO2 and H20 using energy from sunlight.
Part 1: sunlight captured in Atp and nadp
Part 2: energy released atoms in CO2 adn H20 and recombine to C6H12O6 & O2
What goes in? Mater
Out? Sugar
Energy in? Heat
Out? Chemical

Function: Capture sunlight
Carbon isn't created nor destroyed.

Front 26

For cellular respiration, be familiar with the following:

What is its basic function?
What enters and leaves the process in terms of matter and energy?
What happens (in general) in this process?
How does it obey the law of conservation of matter conservation?
How does it obey the laws of thermodynamics?

Back 26

Breakdown of glucose into CO2 and H2O releasing energy for ATP production.
energy released
atp produced
matter in? sugar
out? co2
energy? chemical
out? chemical
basic function: capture sugar energy and release atp
sugar broken down releasing atp
no matter created nor destroyed
heat given off.
