Answer:
Empirical evidence of his ideas
Explanation:
The scientific process involves the formulation of hypotheses that enable to answer questions about the real world, and then to carry out experiments or observations that are used to confirm (or reject) such predictions. In the last 160 years, Darwin's ideas on 'descent with modification' have constantly been subjected to experimental assessment, and obtained data confirmed his observations. For example, molecular evidence based on the DNA and RNA -which constitute the genetic material of all living organisms- has shown the conservation of this process. In consequence, molecular evidence has been used to construct 'evolutionary' phylogenetic trees from DNA/RNA sequences. Moreover, evidence in genetics has shown the critical role played by mutations in the mechanism of natural selection proposed by Darwin, thus also confirming his theories. These are only some examples, and supporting evidence confirming Darwin's ideas has been collected from different research fields ranging from ecology to molecular biology.
Answer:
The correct answer is carbon.
Explanation:
Carbon is the major constituent of almost all organic compound.Carbon in form of carbon dioxide is used during photosynthesis in which the CO2 act as reactant that interact with water to generate glucose and oxygen.
On the other hand carbon is found in carbohydrates such as glucose contain 6 carbon atoms,found in protein which contain a carboxy terminal end and an amino terminal end,found in the fatty acid monomers of lipid molecules.
The correct answer is a law
Laws explain what occurs, not why it occurs. This is a law because it states that a limp stalk of celery will become crisp if put into ice water. There is no explanation why or how it occurs, only that it will happen.
