Q

identify archaea

A

unicellular, autotrophic, prokaryotic, has cell wall

18
Q

identify protista

A

mostly unicellular, both heterotrophic and autotrophic, eukaryotic, usually no cell wall

19
Q

identify plantae

A

multicellular, autotrophic, eukaryotic, have cell walls

20
Q

identify fungi

A

multicellular, heterotrophs, eukaryotic, cell walls made of chitin

21
Q

identify Animalia

A

multicellular, heterotrophic, eukaryotes, lack cell walls

22
Q

what was the original name that all bacteria were once grouped under?

A

kingdom monero

23
Q

what are the 3 bacterial shapes

A

sherical- coccus
rod- bacillus
coil- spirillum

24
Q

what are the simple colonies

A

mono- one
diplo- 2
staphylo- clusters
strepto- chains

25
Q

difference between eubacteria and archaea bacteria

A

Archie can live through rough conditions

eubacteria are found everywhere

26
Q

difference between conjugation and binary fission

A

binary copies the nuclear and splits

conjugation joins a partner and swaps DNA

27
Q

some roles bacteria have in an ecosystem

A

decomposing and recycling nutrients.

28
Q

different conditions bacteria survive in

A

extreme PH, lakes and springs, harsh conditions.

29
Q

examples of benefcial bacteria and harmful bacteria

A

beneficial - lies in gut and helps break down food

harmful- E.Coli goes in gut and makes people sick.

30
Q

why are viruses not considered living?

A

no charecteristics of living cells, must invade a cell to reproduce.

31
Q

compare DNS. and. RNA

A

DNA- replicate in the host cytoplasm directly

RNA- inject RNA in cytoplasm of host cell to replicate.

32
Q

compare lytic and lysogenic cycle

A

In the lytic cycle, a virus quickly makes copies of itself and bursts the host cell. In the lysogenic cycle, the virus sneaks its DNA into the host’s DNA and stays hidden for a while before it can become active

33
Q

why is there a new flu shot every year

A

bacteria is always evolving and becoming stronger.

34
Q

positive uses for viruses

A

phage therapy to kill harmful bacteria

35
Q

what is a vaccine? how do we develop immunity?

A

a vaccine puts the virus in you so you develop the antibodies to fight it. we develop immunity by exposure to viruses that develop antibodies

36
Q

are protists considered eukaryotic and unicellular ?

A

yesh

37
Q

how do protists obtain nutrients

A

some autotrophic and make their own food through photosynthesis, while others are heterotrophic and consume organic matter or other organisms.

38
Q

the importance of protists in ecosystems

A

help keep bacteria in check

39
Q

what is antibiotic resistance and how can it affect your life?

A

decreased ability to treat infections and illnesses in people which can lead to death and illness

40
Q

what are the 3 domains

A

ARCHAEA BACTERIA- ancient, can live through rough conditions.

EUBACTERIA- contains bacteria and cyanobacteria.

EKARYOTES- have a nucleas and organelles

41
Q

what is cladogram and phylogenetic trees

A

phylogenetic Is the eveloution

caladogram are observable traits
