The Nervous System is the power source of your body. Using electrical impulses, your nervous system helps control your muscle movements. The two main functions are the Sensory(afferent) division- which brings information to your brain. Then your Motor(efferent) division- which sends signals out.
Polygenic inheritance. The characteristics of a person aren't controlled completely by a single gene, but rather several genes that generally only make a small contribution to how the child turns out in the outcome. At one point there was a study that showed over 400 genes were linked to height, so imagine any other characteristics of a person. Environmental effects also serve a large purpose in how a child is to turn out. These children may all be growing up in the same environment, however that's not to say they all grow up the same. They could all be treated the same way and react differently to it, this counts both for physical and mental traits. All human's features such as eye colors, hair color and height are determined by several different genes. As an example, there are around 2 major eye color genes, however there are also around 14 different genes that actually contribute in determining a person's exact eye color. Some are bound to look the same, as they have the same parents, however, just because they have the same parents doesn't mean they all will look exactly alike.
An advantage of using models to represent the carbon cycle is: B. show a complete and detailed account of every event in the cycle.
A carbon cycle refers to the series of biogeochemical processes through which carbon atoms or carbon compounds are interconverted and used by living organisms within an environment, especially by transporting carbon from the atmosphere to planet Earth and then back to the atmosphere.
Basically, there are four (4) main processes that are associated with carbon cycle and these include:
- Combustion such as burning of fossil fuels.
A model can be used to graphically illustrate or simulate the all of the activities (events) that are taking place within the carbon cycle.
Hence, an advantage of using models to represent the carbon cycle is that it would illustrate (show) a complete and detailed account of every event in the cycle.

Answer - A
Prokaryotic cells, being unicellular organisms, do not have a defined nucleus. They have a nucleoid in place of the nucleus which is formed of a single chromosome consisting of double stranded DNA.
