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.

Answer:

A

Explanation:

<em>The correct option would be </em><em>A.</em>

<u>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.</u>

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.

Compare photosynthesis and respiration with regard to each of the following
docker41 [41]

Answer:

Explanation:

Photosynthesis Vs. Respiration

1) Photosynthesis gets it's energy from sunlight, and uses the sunlight to change water and CO2 into energy. Cellular respiration gets it's energy from glucose molecules and oxygen.

2) Photosynthesis uses energy, CO2, and water to make energy and releases oxygen. Cellular respiration uses glucose molecules and oxygen to make energy, and releases CO2 and water.

3) Cellular respiration takes place in the mitochondria, and photosynthesis takes place in chloroplasts.

How does a prokaryotic cell such as bacteria differ from eukaryotic cells?​
LenKa [72]

Answer:

The main difference is that EUKARYOTIC cells <em><u>have</u></em> a nucleus while a PROKARYOTIC cell <em><u>does not</u></em>. Instead, prokaryotes have free floating genetic material.

Explanation:

To help you remember this distinction:

EU = YES eukaryotes <em><u>HAVE</u></em> a nucleus.

PRO = NO prokaryotes <em><u>DO NOT</u></em> have a nucleus.

I hope this helps and good luck with your assignment.
