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.

Explanation:
Answer:
In the Eukaryotes, the cytoplasm functions as the site of energy production, storage, and the manufacture of cellular components.
Answer:
Due to presence of ocean near it.
Explanation:
The heat capacity of water is higher than soil means that soil quickly heats up at day time and cool down at night whereas, water takes more time to heat up and cool down so that's why those areas present far from ocean observe high fluctuation in day and night temperatures due to quickly heat up and cool down as compared to those areas present near water such as coastal areas which takes more time to heat up and cool down..
