Answer: B. It is associated with a negative change in free energy.
Explanation:
<u>A polymer is an organic compose made of many simple molecules </u>that are repeating structural units called monomers. Examples of polymers are DNA, lipids, carbohydrates and proteins.
Polymers are broken down into monomers in a process known as hydrolysis, which is a reaction that splits the bond between monomers. During these reactions, the polymer is broken into many components.
This process of breakdown is called catabolic reactions, which, as it was said, is the break down of larger molecules into smaller molecules through the hydrolysis of its bonds. <u>This reaction releases energy which was found in the bond between this monomers.</u> And, when energy is released, there is a negative change in free energy. This means there is more free energy available for the cell to be used.
Alfred Marshal was one of the most influential economists of his time and the author of the Principles of Economics book which was the principal economic textbook in England for long years. During his economic theory development, he borrowed a concept from the marginalists which is the theory of demand and the collective result of buyers who yearns services and products or the concept of scarcity.
Ok, a few things here:
This is an egg drop experiment, so I'm assuming you are testing out different ways of protecting the egg.
The independent variable is what you want to change: This would be the type of protection you have on the egg
The dependent variable is what would be effected by the changes in the independent variable: which would be something like the integrity of the egg after it hits the ground. You'd have to measure that somehow.
There are two types of controlled variables: <em>Internal and External.</em>
Internal variables are within the scope of the experiment and can be controlled, whereas external variables are outside the scope of the experiment and we have no control over them.
Internal:
- Height of the drop
- Type of egg
- Person dropping
- How the egg is dropped
- Surface being dropped on to
External:
- The person designated to drop the egg is sick
- You run out of eggs to drop
- Somebody loses all the planning for the experiment
- The weather forces you to do the experiment inside versus outside
- The wind blows your egg off course, leading to it hitting the ground at an angle
So, the way your teacher "chucks" the eggs off the roof should be a controlled internal variable. The action should be done as consistently as possible to avoid an uncontrolled variable.
