Q

Enumerate each level of organization (starting from the subatomic particles) and state their respective definitions.

A

Subatomic Particles

proton (p^+) + electron (e^-) + neutron (n^0) = atom

Atom

building block of matter, fundamental unit of an element (ex. O^2, H, Au, etc.)

Molecule

group of arranged atoms
Biomolecules (biological macromolecules/molecules of life)
—-> lipids, proteins, nucleic acids (DNA and RNA)

Organelle

organs of the cell
book: membrane enclosed structure

Eukaryotes: membrane enclosed
Prokaryotes: no membrane bounded organelles

??? prokaryotes have no organelles, all have cell wall?

Biological Organization

Cell

fundamental unit of life

Tissue

group of collaborating cells
substructure of an organ

Organ

group of collaborating tissues

Organ System

group of collaborating organs
*EVERY organ system is essential to the body

Organism

individual living thing
unicellular vs multicellular

Population

group of SAME interacting organisms in the same place

Community

group of DIFFERENT interacting populations in the same place

Ecosystem

Community + setting including the abiotic factors (light, water, mountains, soil, etc.)

Biome

large scale biological communities (same plant growth types????)

Biosphere (highest level of organization)

Earth !! (ex. biotic, abiotic - land, water, lower atmosphere, etc.)

Q

What property of life is shown?

Means of duplicating one’s self, continuing one’s species.

A

Reproduction (key word: copy paste, sexual: copy paste dif font (affected by DNA of other organism), asexual: copy paste) NOTE: through reproduction, species continue to exist (thats why experts often put male and female of the same endangered speices together)

Q

What property of life is shown?

In sexual reproduction, the progeny’s characteristics may be similar to those of the parental organisms. The parental organisms pass down genetic information in the form of genes.

A

genes = segments of DNA

Q

What property of life is shown?

A

Evolution/Evolutionary Adaption???

17
Q

What property of life is shown?

feeling thirsty after running

A

Homeostasis (remember, REGULATION!!, ask yourself “what is being regulated?)

18
Q

What property of life is shown?

ex. 1 when salt is poured on a worm

ex. 2 touching a hot pot

A

Irritability (remember, stimuli, ask yourself “what is the direct reaction/effect, what is the stimuli/cause?”)

19
Q

What property of life is shown?

adjusting the aircon when your hot

A

Homeostasis (what is being regulated? the temperature of your body)

20
Q

Growth or development?

puppy — senior dog :(

A

Growth (growth doesn’t include TOO MUCH change in structure (physical including its abilities), development does)

21
Q

Bonus: recitation

Define and enumerate the properties of life (notice: “all living things”)

A

Order/Cellular Organization

all living things follow pattern/symmetry

Metabolism/Energy Processing

consumers vs producers
ATP - Adenosine Triphosphate
all living things require energy —> transformed to do work/operate

ex. consumers = food –> nutrients —> feed cells —> released: energy

Irritability/Response to Stimulus (singular)

any reaction
all living things’ reaction to stimuli (changes in external/internal environment) varies

Remember: your body tends to adapt and adjust for your benefit

Homeostasis (Regulation)

INTERNAL STABILITY BALANCED while adjusting to external conditions

Growth and Development

G = gradual increase in physical charc, STRUCTURE AND ABILITIES DON’T CHANGE THAT MUCH !!!

D = complete process –> new structures!! and abilities

Adaption

ensure survival, adjust to survive

ex. squirrel - store food

???? Evolutionary Adaption

  develop charc. (ex. grizzly --> polar)

Evolution

massive !! changed over a LONGG period of time (physical and genetic structure)

ex. phylogenetic tree

Reproduction

replicate

ex. starfish leg - regenerate, bacteria - binary fission, cell - cell division

sexual (variation of linkages compared to lower forms) vs asexual repro.

Heredity

all living things posses DNA (genetic system is based on DNA)

Eukaryotic cells: found in nucleolus/nucleus??

Prokaryotic cells: found in nucleoid
