CARDS B2 ( biogenesis, carbon cycle, protozoa and types)

Question 1

Biogenesis

Answer 1

claimed that every living theing is formad from another living thing. Louis paster proved this with the swan neck flask experiment

Question 2

Abiogenesis

Answer 2

aristotles cloims that life could arise from inanimate matter througth spontaneous generation. that worms would come from rotten meat, and tadpoles from mud

Question 3

Carbon cycle

Answer 3

begins through photosyn thesis with the help of the sun, where the plants that capture water from the soil and carbon dioxide from the atmosfere, with the help of the sun during the day, will the transformed into oxygen and will be realeased into the air and glucose that will serve as food for the plants. animals and humans feed on plants and animals, so they adquire carbon and realise half of it through beathing, which retruns to stop ante the cicly stard again

Question 4

Methane gas

Answer 4

is produced in anaerobic situations by anaerobic bacteria, without the presence of oxygen

Question 5

Protozoa

Answer 5

are eukaryotes, unicelluar and heterothophs. its cell has a lot of functions; gas exchange, locomotion, reproduction… most is free1living and others live as mualits. their format elongat and oval

Question 6

Digeston protozoa

Answer 6

are heterothophs, feed on small protozoas, bacterias, algae, fungi.. through the process of phagocytose and pinocytosis

Question 7

Reproduction protozoa

Answer 7

asexual: bipartetion or binary
sexual: by exchand of genetic material

Question 8

Classification protozoa

Answer 8

are pseudopods, cilia, flagela, or may be absent

Question 9

Rhizopods or sarcodina

Answer 9

ameba one types, represents pseudopodes, feeding by phgocytoses reproduction is asexual

Question 10

ciliates or ciliophora

Answer 10

have cilia, have oral grave, where has one smal opening, through whick bacteria enter, is food have macronucleus and micronucleus. reproduction is asexual, bipartion

Question 11

flagellates or masligoplora

Answer 11

they have fagella, representatives include, trypanosoma cruzi which causes chagas disease, trypanosoma gambiense, which causes sleeping disease. its reproduction is asexual by bipartion
