Oparin and Haldane's theory and Miller's experiment are the proof that long complex molecules that carry information such as DNA, might have formed on early earth.
Explanation:
Oparin and Haldane Hypothesis states that life on Early earth could have evolved by chemical evolution.
Oparin and Haldane said that the reducing atmosphere of the early earth caused simple inorganic molecules to react by using sunlight and formed molecules like amino acids and nucleotides.
These monomers combined to form polymers, they would have attained self-replicating tendency eventually these would have assembled into structures and these macromolecules had also made membrane-bound organelle.
Although this hypothesis is not fully accepted but part of it which talks about formation of molecules is accepted.
Millers and Urey in their experiment created an artificial reducing environment like that of early earth. They used a heated pool of water, atmospheric gases like H2O,CH4,N2, NH4 and sparks of electricity. After running the experiment for some days they found that amino acids, sugars, lipids and other organic molecules had formed.
Their hypothesis is not fully accepted but part of is evident that organic building block is formed from inorganic constituent on the earth.
The proposed kingdom of euglenozoa includes protists with one or two flagella emerging from an anterior pocket
This flagella give them the ability to swim/moved throughout the water where they usually live
hope this helps
Answer: True
Explanation: Like all living things, prokaryotes need energy and carbon. They get energy from inorganic chemical compounds.
Chemoautotrophs are organism that utilizes inorganic molecules to supply energy for the organism, and use carbon dioxide as a carbon source. Chemoautotrophs are mostly prokaryotes that break down hydrogen sulfide and ammonia.
Most Eukaryotes cannot utilize these inorganic molecules as energy source.
Answer:
The light is shifted to the red end of the spectrum, as the wavelengths get longer.<em> </em>
4 billion years ago the temperature was much higher due to repeated volcanoes and hot gases present in the atmosphere. There weren't any live forms on earth. ... The atmosphere had a different concentration of gases on the earth. There were no life sustaining gases.
