The Cell Cycle Brittany Jameson Vista College Abstract The cell cycle is made up of five steps. These steps are interphase‚ mitosis‚ cytoplasmic division‚ cell differentiation‚ and cell death. During mitosis there is a series of four stages. The Cell Cycle To start the cell cycle the cells first go through a step called interphase. During this step the cell grows and synthesizes new molecules and organelles. In the S phase the DNA of the cell is replicated in preparation for cell division

Sulfur Cycle Sulfur (S)‚ the tenth most abundant element in the universe‚ is a brittle‚ yellow‚ tasteless‚ and odorless non-metallic element. It comprises many vitamins‚ proteins‚ and hormones that play critical roles in both climate and in the health of various ecosystems. The majority of the Earth’s sulfur is stored underground in rocks and minerals‚ including as sulfate salts buried deep within ocean sediments. The sulfur cycle contains both atmospheric and terrestrial processes. Within the

The Rock Cycle & Classification of Rocks The rock cycle is the formation‚ breakdown and reformation of a rock as a result of sedimentary‚ igneous‚ and metamorphic processes. The rock cycle is an illustration that is used to describe how the three rock types are related and how Earth processes change a rock from one type to another over time. Each group contains a collection of rock types that differ from each other on the basis of the size‚ shape and arrangement of mineral grains. Due to the driving

The Business Cycle The business cycle‚ it is also called economic cycle‚ are periodically and unstable levels in the economy that an economy has in different periods of time.

The Business cycle will guide the businesses‚ industries‚ and companies to act in a specific way‚ depending in which of the 4 phases the business cycle is. Since business cycle could be on

The Nitrogen Cycle The Nitrogen cycle is the exchange of nitrogen gas in the earth’s atmosphere and living organism’s. Nitrogen is a necessity to all living organisms in their production of proteins‚ DNA‚ and RNA in their cells . However‚ only a few organisms can use this gas directly‚ due to the fact that it may limit the growth of plants. Nitrogen takes up about 78% of the earth’s atmosphere. The nitrogen cycle has three main chemical transformations‚ including nitrogen fixation‚ nitrification
