A glass dish containing a few drops of water in the presence of carbon dioxide gas, nitrogen gas, and small organic compounds is

heated by a flame and UV radiation. Which early Earth scenario does this set-up most closely resemble?
a. amino acid formation from organic molecules in ocean water splashing on hot rock, sand, or clay
b. deep sea volcanoes giving off gases, sulfur, and iron to produce organic molecules

The correct answer is (a )

This experiment shows that the life has evolved from the inorganic materials. The substances like carbon dioxide, nitrogen gas when heated and exposed to UV radiation led to generation of life supporting element called as amino acids. The UV radiation and heat provided the energy needed by gases to convert into amino acids.

SashulF [63]

Answer:

The minimum mass of dissolved cholesterol that the new system must be able to detect is 0.43 milligrams.

Note: The question is incomplete. The complete question is:

<em>GenAlex Medical, a leading manufacturer of medical laboratory equipment, is designing a new automated system that can detect borderline high levels of dissolved cholesterol (170, to 200. mg/dL), using a blood sample that is as small as 250 μL Calculate the minimum mass in milligrams of cholesterol that the new system must be able to detect Be sure your answer has the correct number of significant digits.</em>

Explanation:

Range of the equipment to detect cholesterol in blood = 170.0  to 200.0 mg/dL

Minimum amount of cholesterol that can be detected by instrument = 170 mg/dL

Volume of blood sample = 250 <em>μ</em>L= 0.0025 dL (1 dL = 100000 <em>μL)</em>

Amount of dissolved cholesterol in 250 <em>μL</em> sample of blood =

170 mg/dL * 0.0025 dL =  0.425 mg

The minimum mass of cholesterol that the new system must be able to detect is 0.43 milligrams.
