Oxidation process occurring in liver rids bloodstream of not 32% of alcohol present.
Once the alcohol enters the body, 5 percent of it is excreted in the form of the urine and another 5 percent is eliminated from the body by exhaling and the rest of the alcohol is converted to acetic acid by oxidation.
Thus,
Oxidation process occurring in liver rids bloodstream of 90% of alcohol present.
Answer:Extra carbon dioxide in the atmosphere increases the greenhouse effect. More thermal energy is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. This increase in the Earth's temperature is called global warming .
Explanation:
Answer:
In prokaryotes nucleus is not present so replication transcription and translation takes place in the cytoplasm in the prokaryotes while in eukaryotes replication and translation takes place in the nucleus.
In prokaryotes, transcription and translation are coupled but in eukaryotes, transcription and translation are separated by nucleus and post-transcriptional modification takes place in eukaryotes, not in prokaryotes.
In prokaryotes, ATP synthesis takes place in cell membranes because they do not have mitochondria. Eukaryotes contain mitochondria where ATP synthesis takes place in them.
Answer:
1. Greenhouse gases are compounds that are able to trap heat in the atmosphere, keeping the Earth's surface warmer than it would be if they were not present. These gases are mainly carbon dioxide; metahne, nitrous oxide, and flourinated gases.
2. Carbon dioxide enters the atmosphere from animals and plants through the process of respiration and the burning of fossil fuels from industries.
