What are the role of all four types of lipids: fats, phospholipids, waxes, and steroids.
ycow [4]
Steroids
are complex structure four connected rings of carbon atoms. They are cholesterol which is in all body cells and used to synthesize other steroids:sex hormones, such as estrogen, and testosterone and several hormones from the adrenal glands.

Waxes
are comprised of an ester of a long-chain alcohol and a fatty acid. Many plants have leaves and fruits with wax coatings to help prevent water loss.

Phospholipids
consist of Glycerol portion and fatty acid chains. Only two fatty acids chains; in place of the third is portion that include a phosphate group. THe phosphate portion is soluble in water [hydrophobic] forms the ''head'' of the molecule, while the fatty acids portion is insoluble in water [hydrophobic] and forms a ''tail''.

Fats
to store energy for cellular activities. Carbohydrates fat molecules are composed of carbon, hydrogen and oxygen atoms.

Stacey wants to know if plants have the same phototrophic reaction from artificial light as they do from natural light. Using st
joja [24]

Scientific method includes some steps that are necessary for conducting the successful experiment.

1. Make an observation

You observe the growth of the plant under the influence of light (phototropic effect) and you notice that some plants successfully grow under artificial light. You want to compare that growth with growth under the sunlight.

2. Ask a question

How does the light influence plant growth?

Are the wavelengths of the light important?

Is natural light source (sun) better for plant growth...

3. Form a  hypothesis - it is a testable potential answer to the question

For example: Sunlight induces higher phototropic reaction.

4. Make a prediction

Sunlight is richer in red and blue hues which are both extremely important to plant growth.  

5. Test the prediction

Design an experiment by putting one pot with beans outside on sunlight and other under the light bulb. Other conditions such as water must be the same. Monitor their growth for about 2 weeks and measure the results.

6. Analyze the data and make a conclusion.
