Answer:

C. Vitamins

Explanation:

The factor Vitamin is being tested in this experiment. For an experiment to occur, it is necessary that we plan an experimental group as well as a placebo group (control group). In this experiment, all other factors have the same experimental group as well as the same placebo group except for the factor vitamin. The factor 'vitamin' has a experimental group in which the particular vitamin is given to the  object of test and a placebo group in which the vitamin is not given to the object of test. Hence, vitamin is the variable that is being tested in this experiment.

What are the similarities and differences between carrier proteins and channel proteins​
kvv77 [185]
* Channel proteins- these are proteins with a hydrophilic pore where specific ions are able to pass through the membrane. Each channel protein is specific to an ion. This is the only way ions can travel through the membrane. They are trans membrane proteins.

* Carrier proteins- these are proteins which allow larger or polar molecules through the membrane. They are trans membrane proteins.

Carrier proteins essentially “carry" signals that are not soluble in aqueous solution through the blood stream to their target cells. Carrier proteins for hydrophilic signals prevent degradation of the signal. Channel proteins are embedded in cell membranes. They often are receptors (though not always), and when activated, allow specific ions to pass through the membrane.

A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules

The carrier protein facilitate diffusion of molecules across the cell membrane. The protein is imbedded in the cell membrane and covers the entire membrane. This is important because the carrier must transport the molecule in and out of the cell.

Dietary fibre is diffcult to digest ,yet it is advisable to Include in our diet.Why?
iren [92.7K]

Fiber is made out of cellulose. Our body doesn't synthesize an enzyme that digests cellulose(cellulase) that's why we can't metabolize it. fiber is good because it reaches the colon undigested and helps the intestinal fauna and can even prevent colon cancer
