living environment quiz

Question 1

evolution is…

Answer 1

the change within a population overtime

Question 2

the hypothesis of a primitive atmosphere is

Answer 2

the ancient atmosphere of Earth was made up of methane, ammonia, hydrogen, water, nitrogen and carbon dioxide

Question 3

the hypothesis called primordal soup is

Answer 3

as the temperature of the ancient oceans cooled, it started to rain which brought those molecules in the air into the ocean

Question 4

the hypothesis of energy is

Answer 4

energy added into the primordal soup created organic compounds such as amino acids and sugars in the form of heat and electrical.

Question 5

______ and ______ were able to accomplish the energy hypothesis in a lab

Answer 5

Stanley Miller
Harold Urey

Question 6

the hypothesis of protocells is…. _____ was able to do this in a lab

Answer 6

the organic compounds combined to form protocells. while they are not considered alive, they are “life-like”, they can reproduce. Sydney fox was able to do this in a lab

Question 7

the hypothesis of living cells is

Answer 7

from the protocells, the first living cells are formed. they are probably prokaryotes (simple cell), heterotrophic, and anaerobic (there is no oxygen in the atmosphere yet)

Question 8

the hypothesis of development of autotrophs is

Answer 8

from these first heterotrophs, the autotrophs will develop. these organisms are still anaerobic but they go through photosynthesis and adding oxygen to the atmosphere (may take millions of years)

Question 9

aerobic transformation is the most efficient way..

Answer 9

to get energy from glucose

Question 10

the hypothesis of aerobes develop is

Answer 10

as oxygen levels rise in the atmosphere from the anaerobic autotrophs, a new group of organisms develop. these organisms can use oxygen during respiration, also known as aerobes.

Question 11

what is an aerobe

Answer 11

an organism that uses oxygen

Question 12

the only type of rock fossils can be found in is

Answer 12

sedimentary rock

Question 13

the lower the fossil is found in the rock…

Answer 13

the older it is

Question 14

other forms of fossils include..

Answer 14

actual bones
teeth
organisms frozen in ice
organisms trapped in amber

Question 15

amber is

Answer 15

hardened tree sack

Question 16

homologous structures have..

Answer 16

similar anatomy but the structures have different functions

Question 17

homologous structures are used to..

Answer 17

demonstrate common ancestry, that these organisms all developed from a single organism

Question 18

analogous structures are…

Answer 18

structures that have the same function but different anatomy

Question 19

analogous structures do not..

Answer 19

demonstrate anything

Question 20

vestigal structures are

Answer 20

structures that are present but no longer function. it is believed that at one time these structures did function

Question 21

(comparative biochemistry) all living things share the same

Answer 21

basic molecular reactions

Question 22

(comparative biochemistry) all living things use the same

Answer 22

compounds needed to produce DNA

Question 23

comparative biochemistry is one of the

Answer 23

strongest evidences used to support evolution

Question 24

comparative biochemistry is used to

Answer 24

suggest common ancestry between organisms

Question 25

an example of a chemical compound used for comparative biochemistry is

Answer 25

DNA

Question 26

embryology is the study of

Answer 26

embryos

Question 27

comparative embryology studies the

Answer 27

similarities between embryos of different species

Question 28

comparative embryology is used to suggest

Answer 28

common ancestry

Question 29

human embryos, at some point in their devlopment have..

Answer 29

gill slits and a tail

Question 29

“ontogeny recapitulates phylogeny” references to

Answer 29

human embryonic development, means that the human embryo, as it develops, demonstrates all the major evolutionary developments that took place to life on Earth
