Lipid bilayers, which form cell membranes, can only be synthesized by biological organisms. It is believed that the internal compartments of eukaryotic cells, like organelles, developed from invaginations of the external prokaryotic cell membrane. Abiogenesis hypothesizes that life exists throughout the universe and was distributed to Earth via meteorites and asteroids, bringing extremophile bacteria trapped in debris. However, abiogenesis proposes that life arose from non-living organic compounds on Earth, not bacteria from space.

1. Lipid bilayers can only be synthesized by biological organisms. This is supported by the rise of
internal compartmentalization seen in eukaryotic organisms. It is thought that the formation of
internal organelles in eukaryotic cells resulted from the invagination of the external cell
membrane in prokaryotic cells True False Abiogenesis is the hypothesis that life exists
throughout the universe, distributed by meteorites, planetoids and asteroids. The theory of
abiogenesis proposes that life in this planet arouse from extremophile bacteria that came from
outer space trapped in interstellar debris. True False The basic elements that are the building
blocks of life in this planet are only found in living organisms; hence, these are only of biological
origin. This contradicts the theory of abiogenesis. True False
Solution
30) False.
In abiogensis, life arose from non living matter like organic compounds. It didnot arise from
extremophile bacteria.
The panspermia hypothesis is an alternatively theory which suggests life on earth arose from the
microscopic life from meteoroids, asteroids and other small Solar System bodies entered the
earth.
31) False.
Lipid bilayers are liposomes can be made in vitro
