2. A

3. D

4. E

5. C

Explanation:

Energy can be defined as the ability (capacity) to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.

The Law of Conservation of Energy states that energy cannot be destroyed but can only be transformed or converted from one form to another.

Some of the terminologies associated with energy includes the following;

1. Fuel cell: produces electrical energy chemically. It is a technology that operates just like batteries but do not need to be recharged since it doesn't run down. Also, it comprises of two (2) electrodes which are: positive electrode (cathode) and negative electrode (anode), with an electrolyte embedded in between them.

2. Alternative energy: energy sources that are still in development. These includes energy source other than fossil fuels. Some examples are petroleum, diesel and coal.

3. Energy conservation: includes lifestyle changes. It involves energy saving actions in order to reduce the level of energy consumption such as daylight savings, energy saving bulbs, etc.

4. Ocean thermal energy conversion (OTEC): produces electrical energy using the temperature difference between two layers of water.

5. Energy efficiency: percentage of energy that does useful work. It determines the amount of work that can be done at a particular time.

What is geographic variation and how does the term cline relate?
prisoha [69]

Geographic variation was the study or examination that living things which are relatively similar are different because of their habitat and geography was dissimilar. Comparable organisms parted ways by physical features and global positioning.

It depends on the position of the species a cline can happen. This can relate to a specific one of two or more substitute forms of a genetic factor that arise by transformation and are found at the same place on a chromosome which will assist in surviving of a different but reachable geographic location.
