All living organisms are composed of one or more cells‚ and like any living organism‚ cells are made up of smaller structures that help them function. In the context of cells‚ these smaller structures are referred to as organelles and each organelle has its own unique function that has developed over time. While we are typically aware of how these organelles function‚ how they evolved raises several questions. The main model for how eukaryotic cells evolved over time is the endosymbiont theory. This

When dehydrated‚ the colonists would drink even more of the polluted water‚ leading to further dehydration and eventually diseases such as dysentery and giardia. In Document C‚ it states that thirty-nine of the 104 original colonists were sailors.

Investigatory Project (Natural Mosquito Repellent) Abstract Mosquito repellents are essentially required these days. Mosquito coils are one of the cheapest and effective way of avoiding them‚ but this coils are made up of chemicals which can harm our health. So we thought about making a substitute mosquito coil that is not harmful to our health and that is the Anstor katol a natural and environmental friendly coil.
