The answer would be : <span>It is a well supported explanation which cannot become a law.
A law and a theory are different you know. In fact, the law is universel. This applies for everything unlike a theory which explains in particular why something is happening.
Any doubts ?
Hope this helps !

Answer:
the internal organ in which the major part of the digestion of food occurs, being (in humans and many mammals) a pear-shaped enlargement of the alimentary canal linking the esophagus to the small intestine.
Answer:
The correct answer is "high heritability".
Explanation:
Concordance, is a term used in genetics to describe the probability that one of the twins have certain trait if his brother certainly has it. A high percentage of concordance, such as 75%, is translated into high heritability since monozygotic twins have identical genomic sequences. Additional information to determine heritability will be to study the exposure to similar environmental conditions, since environment can also affect the presence of certain traits.
Answer:
The bacterium Vibrio cholerae is the primary cause of cholera disease that mainly infects the small intestine and primarily leads to the dehydration of the body.
Explanation:
The genetic analysis reveals that the aforementioned causative bacteria surpass the acidic conditions of the stomach and eventually reaches the intestinal wall and attaches to it. This is followed by the production of toxic protein by the bacterium. This protein is taken inside the cell via receptor mediated endocytosis followed by its binding to the host protein Arf6. This binding leads to the production of cAMP that results in the dehydration process. This mechanism leads to excessive accumulation of chloride ion in the intestine preventing the entry of sodium ion.
These two ions are associated with the creation of water-salt environment in the intestine that leads to tremendous diarrhea via the process of osmosis.
Hence, we can say that cholera bacterium affects the individuals at the cellular level and osmosis plays a vital role in the process.
Answer:
Energy storage, cell structure, signalling.
Explanation:
The functions that lipids serves in the body is - storage of energy, cell structure and signalling. Lipid is an efficient source and storage of energy. It helps in absorption and transportation of fat soluble vitamins ( A, D, E ,K). lipids work as a building block of cellular membrane. Lipids also act as a chemical messanger
