The continual input of energy, mostly from sunlight, sustains the process of life. Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere. There are a few exceptions to this, such as ecosystems living around hydrothermal vents on the ocean floor, which derive their energy from the chemical compounds such as methane and hydrogen sulfide. In either case, the overall productivity of an ecosystem is controlled by the total energy available.
Answer:
Alanine is obtained as the first amino acid, taking into account that the reaction with the Sanger reagent hydrolyzes N- (2,4-dinitrophenyl) alanine. thus with the fragments of the partial hydrolysis they are organized to create a polypetidic chain
ala-asp-gly-ala
gly-ala-phe
phe-be-wing
be-wing-phe-asp
We obtain that the correct sequence of the peptide is "ala-asp-gly-ala-phe-ser-ala-phe-asp"
Answer:
vaccination
Explanation:
The vaccination has been one of the most revolutionary inventions in the medical field. This invention helped protect people from numerous diseases, some being totally neutralized, while some having only minor effects on the human body. The vaccination basically is a way of enhancing the immune system of the body by injecting in it a weakened form of the pathogen. In this way, the weakened form of the pathogen is not capable to harm the body, and the body is not fighting against it, but instead the pathogen becomes part of the body and its defense mechanism, so when the pathogen strikes, the body has a counter attack and defeats it.
