Question 5:
A scientific theory should not be regarded as reliable (false).
Scientific theories are reliable.
Question 6:
It is best to use a line graph to show change over time.
<span>To determine the kcal of energy available from the serving of granola, multiply the number of grams of carbohydrate, fat, and protein, and fat by 4,9, and 4, respectively. Then add the results.</span>
25 grams of carbohydrate x 4 kcal/g= 100 kcal
<span> 5 grams of fat x 9kcal/g= 45 kcal</span>
<span> 6 grams of protein x 4 kcal/g = 24 kcal</span>
<span> Total= 169 kcal</span>
Answer: False.
Explanation: The Archimedes screw was initially used for removing water from the hold of a large ship, not for moving people.
<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.
B. If there were no greenhouse effect, liquid water would not exist on the surface of the Earth
D. The Earth has reached thermal equilibrium, emitting the same amount of energy into space as it absorbs from the Sun.
E. The more carbon dioxide there is in an atmosphere, the stronger the greenhouse effect will be
Explanation:
The greenhouse effect plays major role in the climate of our planet in diverse ways:
- it is responsible for the existence of liquid water on the surface of the earth.
- it allows the earth to reach an equilibrium with space in exchange of thermal energy.
- carbon dioxide concentration in the atmosphere has huge roles.
The greenhouse effects results from the abundance of greenhouse gases in the atmosphere. These gases are able to prevent long wave solar radiation from leaving the surface of the earth. When the gases interacts with the radiation, it produces heat that warms the earth surface. Examples of these gases are carbon dioxide, methane, water vapor e.t.c.
The warming of the surface helps to free freshwater trapped as ice and keeps it in the liquid form throughout.
In this exchange of energy, there is a balance between the amount of heat absorbed and radiated back into the atmosphere. As energy enters the earth, it is also radiated out into space. This helps to keep the earth temperature in balance.
