Matter can exist in which of the following states: - CORRECT ANSWER -Gaseous
Solid
Liquid
Amino Acids that must be obtained from food in the diet / cannot be manufactured by the hum
an body are known as while amino acids that are able to be manufactured by the huma
n body are known as . - CORRECT ANSWER -Essential
Non-essential (See 1.2)
Selective Permeability: - CORRECT ANSWER -
is characterized by the ability of certain substances to pass through the cell membrane while ot
her molecules cannot
Lipids are insoluble in water because: - CORRECT ANSWER -Lipids are primarily made up of non-
polar hydrocarbon chains. As water is polar, itBwill only dissolve other polar or ionically bonded s
ubstances. Lipids are non-
polar and this is why they are insoluble in water but can be dissolved with non-
polar solvents such as alcohol (See 1.2)
