assuming that you're asking a multiple choice question, waxing skis reduces friction so that you can move faster on the snow. grease and oil are used as lubricants. they reduce friction in most instances. throwing sand on an icy driveway would increase friction between a cars tires and the ice. a good rule of thumb is that most liquids work as lubricants, most gritty or solid stuff works to increase friction, and powder can do either.
Friction between skis and snow may be reduced by waxing the skis. Air friction is reduced by tucking the body into a streamlined position.
Actually, waxing skis increases friction. Wax is not slippery. If you wanted less friction you could oil your skis.
When you rub a bar of wax on a board, the heat caused by the rubbing causes the wax to melt into bumps all over the board.
A type of wax called cutin is produced by the epidermal cells of plants, forming a water-resistant coating on the surfaces of stems, leaves, and fruits. This helps the apple conserve water and also acts as a barrier to infection. Other than this natural cutin , there is artificial waxing done on apples for preserving. This artificial waxing is legal in US with restrictions on the type of wax used and the thickness etc. As usual, there is illegal waxing also done on apple as an adulteration method.

waxing is growing and waning is decreasing
yes
the wheels, ya.
Getting larger is WAXING. Getting smaller is WANING..
When the visible bright part of the Moon is increasing in size, the term "waxing" is used. When the visible part of the Moon is less and less illuminated each night, the term "waning" applies.

It is called Waxing! _________________________ The Moon is always the same size. What we see increasing is the lighted part of the nearside of the Moon. When it is increasing, we call it "waxing"; when we see it decreasing, the word "waning" is used.

After the New moon, the next phase is the "waxing crescent". "Waxing" in the context means "growing" or increasing. The opposite is "waning", or decreasing.
