Question 1

peer reviewed information

Answer 1

primary and secondary

Question 2

what adaptations allowed plants to colonize land

Answer 2

1 Vascular tissue
2 roots
3 internal gametophytes
4 seed production
5 seed coats

Question 3

Alternation of Generation

Answer 3

species alternate between haploid and diploid phase

Question 4

Life cycle of fern

Answer 4

hermaphrodite. GAMETE
archegonia(eggs) and antheridia(sperm)
male only GAMETE
antheridia.
sperm released, fertilize egg, diploid zygot undergoes mitotic to form embryo, turns into sporophyte

Question 5

processes that produce new species

Answer 5

allopatric speciation
sympatric speciation

Question 6

4 mechanisms of evolution

Answer 6

mutation,geneflow, selection, genetic drift

Question 7

how do selective pressures shape population

Answer 7

less fit or unsexy individuals die and dont reproduce -> genes not passed down

Question 8

ecology

Answer 8

study of interaction of individuals and their environment

Question 9

habitat

Answer 9

ecological environment where an organism lives

Question 10

competition (INTRA VS INTER)

Answer 10

intraspecific competition: competition within population
interspecific competition: competition between 2 species

Question 11

how much energy transfered between trophic level?

Answer 11

10%

Question 12

characteristics of fungi

Answer 12

-made of chitin
-heterotroph
-absorb nutrients from environment using enzymes and stuff
-hyphae

Question 13

lifecycle of fungi sexual

Answer 13

1meiosis to produce spores -> germinate to hyphae, 2 plasogamy: fusion of cytoplasm,
karyogamy: fusion of nuclei
meiosis

Question 14

lifecycle of fungi asexual

Answer 14

spores produces, germinate boom and redo

Question 15

ecological roles of fungi

Answer 15

decomposers, pathogens, most feed on organic matter( saphrocites) mycorrhizzae, lichen(symbiotic relationship)

Question 16

2 types of mycorrhizae

Answer 16

ectomycorrhizae: surround root
arbuscular mycorrhizae: penetrate

Question 17

importance of lichen

Answer 17

symbiotic relationship with photosynthetic cyanobacteria that fixes nitrogen and produces sugar in return for moisture and shelter

Question 22

nematoda body plan

Answer 22

bilateral, triploblastic, hemocoel, no segmentation,

Question 23

anthropoda body plan

Answer 23

blateral triploblastic coelem, tigmatization

Question 24

differences protosomes and deutrosomes

Answer 24

protosomes: determinate, spiral, formation of mouth first
duetrosomes: inteterminate, radial, anus first

Question 25

characteristics of echinoderms

Answer 25

5 fart radial symmetry (bilateral embryo)
-Calcarious endo skeleton
water vascular system modified for locomotion

Question 26

characteristics of chordata

Answer 26

Notochord
dorsal hollow nerve cord
Pharyngeal slits
Post anal tail

Question 27

advantages of radial and bisymmetric

Answer 27

radial: non motile, equal opportunity for each direction
bilateral: motile animals, detect prey in front(cephalization–>sensory anterior)
