Answer:
Regulation of intake is governed by thirst receptors that pick up signals of dehydration and return the body to a rehydrated state.
Explanation:
The state of hydration in someone's body is given by the plasma osmolarity values (the ratio of solutes to water in blood plasma). After regular activities that involve the loss of water, such as urination and sweating, happen, the blood begins to concentrate and the osmoreceptors located in the hypothalamus are triggered to generate a response that leads to water intake.
Answer:
Denatured (unfolded) proteins do not function normally.
Explanation:
Proteins are the polymers made of the alpha amino acids that are linked through the peptide bond. Protein is one of the most important biomolecule acts as the main building block of the body.
Protein are specific in functions and works only when they have correct three dimensional structure. The denaturation of protein causes the change in its structure, makes the protein less folded and the protein is unable to perform its function after the denaturation.
Thus, the correct answer is option (2).
Determined by its primary structure (sequence of amino acids.)
the sequence of amino acids in an protein is determined by the nucleotides in the DNA encoding it
