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.

Explain how carbohydrates and lipids are similar/different.
e-lub [12.9K]

Answer:

Carbohydrates and lipids are similar in that they are both sources of energy but they are different in the amount of energy they produce.

Explanation:

Carbohydrate and lipids are similar in the sense that both of them are  parts of foods consumed by humans and the two marcro molecules are good sources of energy for the body cells. The carbohydrate has to be broken down to glucose before it can be absorbed by the body cells. This is because glucose is the only energy source that the body cells can use. The lipid has to be converted to glucose through biochemical reactions such as gluconeogenesis before the cells can use it.

The basic difference between the two energy sources is that the amount of energy that they supply is quite different. Lipid contains more energy than carbohydrate; carbohydrate can only supply about one-quarter of the energy that lipid can supply.

Pancreatic cells, which secrete a large amount of digestive enzymes, are labeled with radioactive leucine and then chased for se
Citrus2011 [14]

Answer:

Exterior of the cell.

Explanation:

The pulse chase experiment was done to understand the secretion pathway of the protein at different time intervals. The protein travels through the endomembrane system for its secretion.

The cells of the pancreas are labelled with the leucine which is radioactive in nature. The black spots will be shown on the cell exterior as three hours are enough for the secretion of the protein outside the cell.  This indicates that the protein has been secreted out of the cell.

Thus, the answer is exterior of the cell.
