Answer:
There are two possible answers: Deep-sea vents provided the energy needed for the first organic compounds to form OR self-replicating RNA molecules passed on genetic information.
Explanation:
The reason for the first answer is due to the hypothesis that indicates that life (organic molecules) arose from inorganic molecules synthesized from the amino acids in those energy vents. This is called the metabolism first hypothesis. The Miller-Urey Experiment provided evidence that organisms could rise from inorganic molecules (they simulated under the conditions you would see on early Earth). The second hypothesis is the RNA World hypothesis (second answer) which suggests that the formation of RNA that could replicate (possible due to mutation or evolution), led to life that could preserve its genetic integrity through replication (greater stability to the organism) and create lipid bi-layer membranes/other organelles. Some scientists support the Metabolism First Hypothesis, while others are skeptical (this goes for the RNA World Hypothesis as well). However, the RNA World Hypothesis is for more reasonable in the fact that its main point is the fact that RNA molecules were able to replicate and maintain genetic stability despite early Earth conditions. Although either hypothesis could explain why all organisms share the same genetic code, the RNA World Hypothesis better explains the universality of DNA/RNA of genes that we see today.
The human brain consumes up to 20% of the energy used the entire human body which is any other single organ. the brain represents inly 2%of the body wheight yet it recieves 15% of the cardiac output and 20% of the total body oxygen consumption.
<span>The battery which Ryan kept in fridge, assuming it was well protected from any moisture or water, it would tend to play the CD longer than the one stored in a desk drawer. This is because storing batteries in a cool dry location while protected from any moisture or water, can help to prolong shelf life. This is due to the fact that low temperatures tends to slow down the electric current flow within the electrolyte fluid inside the battery, hence, the rate of power dissipation is reduced thus slowing down of the power drain from battery by the electric current flow .
Thus, the battery stored in the fridge tends to have lost less power, if any, compared to the one stored in a desk drawer.</span>
Well, I'm assuming you're talking about these terms...
Species, Genus, Family, Order, Class, Phylum, Kingdom, Domain
