PLEASEEE HEL TIMES TEST !! Aminoacyl-tRNA synthetase is an enzyme that is responsible for attaching the correct amino acid to the tRNA
molecule. As the mRNA transcript is read by the ribosome, the complementary tRNA molecule then brings the correct
amino acid to the polypeptide chain. Although aminoacyl-tRNA synthetase is very accurate, it will rarely attach the
wrong amino acid to the tRNA. Which of the following could be the cause of an error in this process that results in the
histidine amino acid being substituted for a phenylalanine amino acid, causing a misfolding of polypeptide chain?
O The wobble effect of tRNA will allow aminoacyl-tRNA synthetase to bind to a group of amino acids.
O Aminoacyl-tRNA synthetase will change the structure of the tRNA to allow for binding to a different amino acid.
O Certain amino acids have very similar structures in their attachment ends and can cause aminoacyl-tRNA
synthetase to bind to the wrong amino acid.
O Aminoacyl-tRNA synthetase determines if a misreading error has occurred by the ribosome and will replace the
tRNA anticodon to pair with a different amino acid.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

air enters through the nose, moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi andbronchioles till the alveoli.
