Select the correct answer. Which statement correctly explains the polarity of the water molecule? A. The hydrogen end of the mol
ecule has a partial negative charge and the oxygen end has a partial positive charge. B. The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge. C. Both ends of the molecule have a partial negative charge, which attracts the other water molecule towards itself.
option B) The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.
Justification:
The electronegativity of an element accounts for its relative ability to attract electrons.
Being oxygen more electronegative than hdyrogen (the electronegativity of oxygen is 3.44 while the electronegativity of the hydrogen is 2.20), the electron density will be displaced toward the oxygen, letting it with a partial negative charge and the hydrogen with a partial positive charge.
Finally, since the charge is not symmetrical distributed around a center of the molecule, the molecule ends being polar.
Enzymes. Most enzymes are proteins and therefore their function is specific to their structure. ... The enzyme binds with the appropriate substrate only in the correct alignment and orientation to connect the molecules. The resulting enzyme-substrate complex enables the reaction to occur.
BINOMIAL NOMENCLATURE is a method of naming and classification used for naming and classifying living organism in their respective taxa in accordance with their characteristics.
CARLOUS LINEOUS was the scientist who developed this system.
It is confusing to use common names because common names have no scientific basis and are of no use while naming organism also many organisms may have different common names in different areas of world.
Scientists use Latin or Greek language for naming and classification.
The first name in a scientific name is the genus name.
The second name in a scientific name is the specie name.
Molly's kidney will adapt to this sodium meal by increasing the sodium content of the urine and later decreasing the amount of pure water in the urine. Its accomplished through the hormone aldosterone. as dietary sodium level increases, the secretion of aldosterone decreases resulting in an increase loss of sodium from body and decreases loss of pure water.
