The essential amino acids cannot be produced in the human body and hence these amino acids have to be obtained through the diet. Hence these amino acids have this characteristic that these cannot be produced in the human body and have to be obtained through diet this makes them essential. Hence those nine amino acids are considered as the essential amino acids.
Trophic level: the feeding level of an organism in a food web or chain. Food web: a diagram showing a series of interconnected food chains and the flow of energy through an ecosystem. Food chain: a diagram showing the flow of energy from one trophic level to the next. E.g. Consumer or decomposed Consumer: an organism which feeds on other organisms to obtain its nutritional requirements (part of a food web/chain). Producer: an organism capable of trapping the suns energy and converting it to sugar in the process of photosynthesis. Therefore the term food web is the term used to include all of the above.

Answer:
Averaging the fitness of its members.
Explanation:
The fitness of a whole population can also be determined by averaging the fitness of its members. Absolute fitness is the ratio between the number of individuals with a genotype before selection versus after selection. Fitness is usually discussed in terms of genotypes, or collection of genes.
The correct answer is B combustion.
Lavoisier’s oxygen theory of combustion was one of his most notable contribution to science and earned him the title of the “father of modern chemistry”. He recognized the combustible property of oxygen and that phosphorus and other metallic elements increased in terms of weight when burned.
