1. Cell starts into mitosis phase of the cell cycle.
2. Helicase begins to break the hydrogen bonds between the nitrogen bases. (The double helix has to be unwound in order to expose the nucleotides)
3. DNA polymerase attach the free-floating nucleotides to the exposed nitrogen bases. (this allows a new DNA strand to be made on the existing one)
4. Free floating nucleotides pair up with exposed nitrogen bases (this is what really builds the new strand, based around the template strand)
5. Two new molecules of DNA are created
Statements:
Adenine
Cytosine (Car in the Garage, Apple in a Tree is a good trick to know how they pair)
DNA
Replication
Double helix

I claim light, water and minerals are the limiting factors that might affect the growth or diversity of our ecosystem.
Abiotic factors are the non-living components of an ecosystem and include light, minerals, water etc. These are the vital components without which an ecosystem cannot exist.
Light is essential not only for photosynthesis in plants, but also in maintaining a livable temperature on Earth. Day and night cycles affect and form all the organisms as well as the interactions between them .
Water in itself makes possible the process of photosynthesis in plants as well as the majority of chemical processes in living organisms. Furthermore, makes possible the absorbtion of soil nutrients by the plant roots. Without water, life would not be possible.
Minerals are trace elements that exist in all living organisms and are vital to the existance of life. They can be found in both organic and inorganic combinations and are responsible for the existance and functioning of all mental and physical processis. They are most important in maintaining all physiological process as well as acting as catalysts for many biological reactions.
Ecosystems are complex systems that are built on complex interactions between organisms and their physical environment. In order for any life to exist, certain conditions and requirements need to be fulfilled. Among these, light, water and minerals are vital to the existance of life. Without these three, life as we know it would not be possible. They shape both the ecosystem and the organisms living in a certain area. Their abundance dictates both the growth and diversity of our ecosystem.

<span>Observing that fibroblasts grew better in cell culture when blood serum was added to the growth medium instead of blood plasma. Thus proving that there was a substance in serum that made it easier for fibroblasts to grow.</span>
