<em>The structure of the plasma membrane is to protect the cell from its surroundings. The plasma membrane is composed of a bilayer of phospholipids, with their hydrophobic, fatty acid tails in contact with each other. The landscape of the membrane is studded with proteins, some of which span the membrane. Some of these proteins serve to transport materials into or out of the cell. Carbohydrates are attached to some of the proteins and lipids on the outward-facing surface of the membrane. These form complexes that function to identify the cell to other cells. The fluid nature of the membrane owes itself to the configuration of the fatty acid tails, the presence of cholesterol embedded in the membrane (in animal cells), and the mosaic nature of the proteins and protein-carbohydrate complexes, which are not firmly fixed in place. Plasma membranes enclose the borders of cells, but rather than being a static bag, they are dynamic and constantly in flux</em>.
Hope this helped you-have a good day bro cya)

Answer:
4. You want to figure out more about the atmosphere of the planet from question 2, so you have measured the star’s absorption spectrum during the planet’s transit. Using the sample spectrum of elements AND the spectrum from the star you observed, figure out what elements the planet’s atmosphere is made out of.
a. What is it made out of?
b. Is there any oxygen in that atmosphere?
c. Would there be a chance of life (like ours) on this planet?
Explanation:
zapped gas/liquid into amino acids
many amino acids thought to have come from meteorites
a mixture of gases and water that Miller thought were present on early Earth was heated and zapped with electricity to mimic lightning. This created five identifiable amino acids
newscientistcom
We know amino acids exist in some kinds of meteorites and interplanetary dust
Many left-handed amino acids were found inside the Murchison meteorite. Most were kinds not found on Earth.
92 different amino acids have been identified in the Murchison meteorite. Of these, only 19 are also found on Earth. The remaining amino acids have no apparent terrestrial source. This discovery led scientists to consider the possibility that Earth's life forms originated elsewhere in the universe. And the same cosmic process that may have helped life arise on Earth could also be seeding life elsewhere in the universe
