biodiversity

Question 1

biodiversity

Answer 1

variety of organisms
genetic differences
the ecosystems

Question 2

species diversity

Answer 2

variety of different species in an area
most basic level
plants to microorganisms

Question 3

genetic diversity

Answer 3

variations among genetic resources

Question 4

ecological diversity

Answer 4

an ecosystem= living + nonliving and their interaction
diversity among ecosystems

Question 5

advantages of biodiversity

Answer 5

supports food security
sustains livelihood through overall genetic diversity
a large number of plants=variety of crops
greater species diversity ensures natural sustainability
healthy ecosystems can withstand disasters
humans have negative effect on biodiversity

Question 6

prokaryotes

Answer 6

prokaryotic cells , no nucleus

Question 7

eukaryotes

Answer 7

eukaryotic cells, nucleus+ organelles

Question 8

features of organisms

Answer 8

nutrition= autotrophic(makes own food), heterotrophic(feeds on living)

cell organisation=unicellular, multicellular

cell type= eukaryotes(genetic material surronded by membrane),
prokaryotes(lacking a membrane)

respiration=aerobic, anaerobic

reprodution

movement

Question 9

domains of organisms and their kingdoms

Answer 9

archea (archeabacteris)
bacteria(bacteria)
eukarya(protista, fungi, plantae, animilia)

Question 10

animal kingdom two catergories

Answer 10

vertebrates (warm blood cold blood)
and
invertebrates( with jointed leg without legs)

Question 11

warm blood ex:

Answer 11

mamallas bird

Question 12

cold blood ex:

Answer 12

fish reptile

Question 13

with jointed leg

Answer 13

with 3 or more than 3

Question 14

without legs

Answer 14

worm like and not worm like

Question 15

animals characteristics

Answer 15

multi celled
heterotrophic eukaryotes aerobic
sexual reproduction
movement

Question 16

how many species are there?

Answer 16

9-10 million
most known are insects(1 million)

Question 17

plant kingdom

Answer 17

species of vegetation
one of the oldest
immobile, autotrophic, multicell, eukaryotic
sexual or asexual
vascular and non vascular

Question 18

fungi

Answer 18

unicellular + multicellular
RECYCLING
chitin in their walls, feed of other living things,
reproduce through spores
some have toxins
beneficial ones= penicilin+antibiotics

Question 19

protista

Answer 19

primitive of eukaryotes
eukaryotic organisms that are not deemed to be animals, plants, fungi such as protozoa
ex: euglena, amoeba, paramecium, algea
some have organelles that are found in animal cells(mitochondria), while others have organelles that are found in plant cells(chloroplast)

Question 20

monera kingdom(archra+eubacteria)

Answer 20

microscopic+prokaryotes
present in all habitats and is made up of single-cell things with no defined nucleus
most bacteria are aerobic and hetetrophic
archea usually anaerobic and metabolism is chemosynthetic
some bacteria are photosynthetic

Question 21

archabacteria

Answer 21

cell wall composition= for extreme conditions

archea of methonogon=found in guts of humans and animals

reproduce by binary fission(asexual)

1 circular chromosome

use flagella to move

Question 22

eubacteria

Answer 22

considered true bacteria
in every environment
compose human microbiota
ensures our body to function normally

Question 23

human microbiota

Answer 23

healthy growth
protect body
help digestion
regulate moods

Question 24

distruption of microbiata

Answer 24

know as dysbiosis

results in obesity, dermotits, neurological imbalance, irritable bowel syndrome

cure= probiotics, prebiotcs

Question 25

how do gut bacterias affect our body?

Answer 25

gut-brain= autism, psychiotric disorders, pneumonia, neurodegenerarive disorders heart diesease= hearth failure, atheroscleros thrombiosis gut-skin= psoriosis, acne vulgaris, skin cancer metabolsim=obesity, T2 diabetes, cancer, mitochondrial dysfunction gut-lung=asthma, lung cancer, obstructive pulmonary disease

Question 26

microorganisms on surface...

Answer 26

guard against invasion healing wounds immune syustems produce signaling molecules

Question 27

gut...

Answer 27

harbores the highest amount of microorganisms microbes in gut posses enzymes to digest carbohydrates and extraction of nutrients

Question 28

intestinal microorgnaisms...

Answer 28

produce K2 B12 active role in medication we ingest first to interact with drugs

Question 29

babies???

Answer 29

get microorgansisms from their moms during delivery lactobacilli= in moms vagina= cesarean= colonize baby's intestines to help in digestion of milk after birth microorganism are obtained from diet= breast milk= acquire bacteria from mother's skin that colonize baby's intestines

Question 30

ecosystems 2 components

Answer 30

abiotic(non-living) biotic(living)

Question 31

it takes up ... years to get enough microbes

Answer 31

2

Question 32

tardigrades

Answer 32

micro animal live in water moss algae for over 500 million years survived artic, space, turn into tun= release water this is called cryptobiosis organs protected by sugary gel called trehalose can survive 1000x more radiation than us

Question 33

can plants communicate using the electricity

Answer 33

yes

Question 34

kingdoms are

Answer 34

Archaebacteria (ancient bacteria) Eubacteria (true bacteria) Protista Fungi Plantae Animalia
