External stimuli are changes outside the body, or knowledge that is passed to us through our senses. This could be cold or hot weather, light levels, or danger. Examples: if someone threw a ball at you, you flinch. If someone shines a bright light in your eye you close your eyes.

hodyreva [135]

<u>Answer</u>:

There are a number of lipids that are found in foods and contribute to various functions in the body. Triglycerides are the most common lipid found in food and in the body; they consist of a <u><em>Glycerol</em></u><u> </u>backbone attached to three fatty acids.

Fatty acids are classified based on the degree to which the carbon chain is saturated with <u><em>Hydrogen</em></u>

A fatty acid is <u><em>saturated </em></u>if it contains no carbon-carbon double bonds,   <em><u>polyunsaturated </u></em>if it contains  two or more carbon-carbon double bonds, and<em><u> monounsaturated </u></em>if it has only one carbon-carbon double bond.

The unsaturated fatty acids can exist in one of two structural forms: the <em><u>trans </u></em>form occurs when hydrogens on both carbons forming the double bond lie on opposite sides of that bond.

When hydrogens on an unsaturated fatty acid lie on the same side of the carbon-carbon double bond, a <u><em>cis </em></u>formation exists.

Eva8 [605]

Answer: True

Explanation: The plasma membrane is a membrane the protects the cell and its environment. It regulates what goes inside and what comes out of the cell. .

Plasma membrane as a structure composed of multiple components, including phospholipid bilayer, carbohydrates, and other lipids. The phospholipids possess one head and two tails. The head is basically polar and hydrophilic (water-loving) while the tails are non-polar and hydrophobic (water-fearing).

The plasma membrane is decorated with proteins. Some protiens are extrinsic proteins that run halfway through the membrane, while others are called integral proteins that go entirely through the membrane. The function of these proteins is to serve as channels to allow the molecules to enter and leave the cell.
