According to most theories about the evolution of early life on earth, the atmosphere had an abundance of ammonia, methane, and carbon dioxide, shown above. Free energy from lightning could have allowed chemical reactions to occur that generated the precursors to life on earth. Which inorganic molecule(s) are accurately paired with their role in the formation of organic molecules necessary to life? A)Ammonia would have provided the nitrogen found in the amine groups of amino acid and the nitrogenous bases in DNA.

B)Methane would have provided the hydrogen to form water, a universal solvent for chemical reactions supporting life.

C)Ammonia would have provided the electrons to generate ATP using an electron transport chain within the mitochondria.

D)Carbon dioxide would have provided the oxygen needed to perform photosynthesis, resulting in the production of glucose.

A

Explanation:

The correct option would be A.

The presence of ammonia in the atmosphere of primitive earth provided the nitrogen found in the amine groups of amino acid and the nitrogenous bases in DNA. This has been proven through the simulation experiment of the primitive earth's atmosphere by Stanley Miller and Harold Urey.

The water in the primitive atmosphere was formed from the condensation of water vapour from volcanoes that were characterics of the earth's environment while oxygen in itself is not needed for photosynthesis but a by-product of it.

glycolysis

explanation:

glycolysis must occur before any of the other steps can occur.

hope this !

i believe the correct answer is the virus gets an envelope that contains host molecules when it leaves the host cell.

explanation:

during the bidding/release stage of a virus, it encapsulates itself with part of the membrane of the host cells in this case the cells of the monkey and is the reason as to why the scientist found the genetic material of the monkey on the viral cell surface.

further explanation

to understand this answer, we have to know the cycle a virus undergoes to replicate. a virus is basically a bunch of genetic material enclosed in a capsule and lacks any machinery or organelles to ensure their survival so they must enter a host cell in order to get the environment needed to survive. some viruses enter and lyse(destroy) the host cell after they have replicated and undergo the lytic cycle while some enter and leave the cell intact after replicating and these undergo a lysogenic cycle. to enter the cell, they undergo the first process called attachment by binding to specific receptors and co-receptors on the surface of the host cell. after attaching to the cell, they start the second phase called penetration where virus enters or is engulfed whole by the host cell through a process called endocytosis. it is the same process that a cell takes up materials it needs or pathogens around it. uncoating of the virus then happens after the virus has been engulfed and is the third stage. the virus then undergoes releasing of its genetic material in the host's matrix.   the materials then enter the nucleus and undergo biosynthesis by adding themselves in strands of rna being translated and then copies of the virus are produced in addition to the host genetic material. the material/newly formed viral material then undergoes assembly inside the host cell and form a capsule around them. the virus undergoes the last release/budding stage by binding to the host membrane and pushing outwards. in doing so when they tear away from the host membrane, they pick up the genetic material from the membrane of the host cell to form their envelope.
