CO2 in the atmosphere means that..

the first cell

ozone finally forms fully
incorrect
7.
microspheres

8.
biogenesis
incorrect
9.
primitive atmosphere
incorrect
10.
as the rain erodes crust, what enters the water basins?
incorrect
11.
endosymbiosis
incorrect
12.
origin of life/organic soup theory
incorrect
13.
these simple organic molecules form more complex organic molecules such as...
incorrect
14.
abiogenesis or spontaneous generation
incorrect
15.
what types of energy convert primitive gases into ions...
incorrect
16.
primitive earth, 4.5 billion years ago
incorrect
17.
phospholipids- important why?
incorrect
18.
ions recombined forming WHAT simple organic molecules?
A.
the relationship (mutualism) between organisms like the mitochondria, chlorophyll and the ancient prokaryotic cells which eventually led to simple cells becoming complex and life finally evolving into actual organisms.
B.
since the glycerol part of phospholipids are hydrophilic while the fatty acids are hydrophobic, they formed spheres called microspheres; eventually, proteins entered these spheres. this led to the formation of cell membranes.
C.
all hot magma; the atmosphere is cold, so the earth is slowly cooling.
D.
monosaccharides, glycerol, fatty acids, amino acids, and nucleotides.
E.
life comes from life
F.
heterotrophic, anaerobic, and prokaryotic; anaerobic respiration led to CO2 being released into the air.
G.
one type of molecule- like a ring of phospholipids
H.
UV, heat, radioactive materials, and lightning
I.
phosphorus and salts enter the water basins, meaning that important materials enter the water and can bond with ions to form the building blocks of life.
J.
chemosynthesis can occur
K.
polysaccharides, lipids, proteins, DNA, and RNA.
L.
life comes from nonliving things. ex: people believed that the Nile mud spawned snakes and frogs, and food waste was the direct cause of maggots.
M.
had H2 (hydrogen gas), H20 (water vapor), NH3 (ammonia), CH4 (methane). There is no free oxygen. There is also no Ozone layer (O3) which means the sun is shining too brightly- radiation!
N.
water pulls ions out of the atmosphere and into the newly collected water basins (since water has a polar covalent bond)
O.
life can leave the seas.
P.
discovered in the 1920s by Oparin and Haldane.
Q.
boiled chicken for LESS than five minutes and then placed in a sealed flask. He found that microorganisms grew. (proving abiogenesis)
R.
1953- duplicated the primitive atmosphere and after one week produced two amino acids.
Type the Answer that corresponds to the displayed Question.
incorrect
19.
DNA in the core of a microsphere/coacervate
Type the Question that corresponds to the displayed Answer.
incorrect
20.
aerobic respiration can occur--> leads to Eukaryotic cells.
incorrect
21.
tried to prove abiogenesis. he put a dirty shirt into a barn; 21 days later, he found mice there. he thought this proved the theory.
incorrect
22.
he discovered microorganisms.
incorrect
23.
several types of molecules- ex, phospholipids with proteins throughout (NO DNA-meaning not a cell)
incorrect
24.
photosynthesis being able to occur (more sun protection with Ozone layer); this means that free oxygen can also enter the atmosphere.
incorrect
25.
took chicken broth and boiled it for more than 5 minutes. Then he made an S-shaped bottle to prove that the bacteria is caused by undercooked chicken, not out of the 'air' or by the chicken. microorganisms linked to disease.
incorrect
26.
boiled chicken for more than 5 minutes and then placed in a sealed flask. He found that NO microorganisms grew. (disproving abiogenesis)
incorrect
27.
took the Urey/Miller experiment further and produced proteins.
incorrect
28.
meat into a glass jar and found that flies were inside; then covered with an airtight top; found that no flies were there. people claimed he had killed the life (gives rise to flies) of airflow; so then, he covered jar with cheesecloth; still no flies.
