BIO LAB FINAL

Question 1

scientific literature

Answer 1

scholarly publications that report OG empirical/theoretical work

Question 2

3 types of sci lit

Answer 2

primary: sci papers that report OG findings
secondary: review papers and books
tertiary: national geographic

Question 3

main parts of every sci article

Answer 3

abstract, intro, methods, results, discussion, acknowledgement, references

Question 4

importance of each part of sci articles

Answer 4

abstract = short summary
intro = bg info
methods = what they did
results = data collected
discussion = explain results
acknow. = thank you for helping
references = citations

Question 5

2 microscopes

Answer 5

compound = bacteria, microbio, light goes through
dissecting = bee, bigger things, light on

Question 6

steps of sci method

Answer 6

observation, question, hypothesis, experiment, analysis, conclusion

Question 7

can theories become laws

Answer 7

NO
laws are generalizations of a pattern, and theories are explaining why that pattern exists

Question 8

types of investigations

Answer 8

experimental: treatment
observational: no treatment

Question 9

hypothesis

Answer 9

proposed explanation for phenomenon, testable and falsifiable

Question 10

variables

Answer 10

independent: manipulated x axis
dependent: measures y axis

Question 11

sowbugs

Answer 11

scavengers, crustacea, have gills, and live in wet environments

Question 12

components to a graph

Answer 12

axi labels, units, intervals, and captions

Question 13

structure of cells

Answer 13

genetic material, cytoplasm, plasma membrane, ribosomes

Question 14

cell theory

Answer 14

all organisms are made of cells
cells are basic unit of life,
all cells come from pre exisiting cells
FUNGI ARE MOST CLOSELY RELATED TO ANIMALS

Question 15

endosymbiotic theory

Answer 15

eukaryotes rely on prokaryotes which are in eukaryotes (mitochondria and chloroplasts)

Question 16

pro vs eukaryotes

Answer 16

P= no nucleus, simple, unicellular, no organelles
E= nucleus, complex. unicell OR multicell, organelles

Question 17

gene

Answer 17

individual coding of DNA

Question 18

enzymes in DNA

Answer 18

helicase= unzips
DNA polymerase= creates lagging strand
complementary strand = opposite strand
ALL OCCURS IN NUCLEUS

Question 19

transcription

Answer 19

DNA polymerase makes mRNA
begin at start codon (AUG) then finish at stop codon

Question 20

translation

Answer 20

in cytoplasm
mrna binds to trna with amino acid, peptide bond shifts, trna exits, starts over

Question 21

mutation that occured to serratia

Answer 21

thymine dimer

Question 22

gene mutations

Answer 22

substitution, inversion, insertion, deletion

nonsense= codes for diff AA
silent= codes for same AA

Question 23

organism is diploid for half its life and haploid for another

Answer 23

alternations of generations

Question 24

meiosis in sporangia

Answer 24

creates meiospores

Question 25

everything fused together in slime mold

Answer 25

plasmogamy

Question 26

mature plasmodium

Answer 26

is diploid

Question 27

structures for meiosis

Answer 27

is haploid

Question 28

What are the four causes of mutations that we talked about

Answer 28

Mutagens
Carcinogens
Replication errors
Transposons

Question 29

Every scientific name must follow two rules, besides how they are written. They can’t be __ and they cant be __.

Answer 29

They can’t be redundant, and they can’t be ambiguous

Question 30

The group opisthokonts is represented by three groups. What are they?

Answer 30

Animals, chanoflagellates, and fungi

Question 31

Bryophytes have to grow close to, or in water. Why is this?

Answer 31

They do not have vascular tissues for water and nutrient transport
