The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;

Prokaryotic Cell Structure Bacterial Cell Structure Mariana Ruiz Villarreal/Wikimedia Commons Prokaryotes are single-celled organisms that are the earliest and most primitive forms of life on earth. As organized in the Three Domain System‚ prokaryotes include bacteria and archaeans. Prokaryotes are able to live and thrive in various types of environments including extreme habitats such as hydrothermal vents‚ hot springs‚ swamps‚ wetlands‚ and the guts of animals.

Why is cell differentiation important in the formation of organ systems? - When a cell differentiates‚ it becomes more specialized and it may undertake major changes in its size‚ shape‚ metabolic activity‚ and overall function. Cellular differentiation is important and occurs so cells can specialize for distinct functions‚ such as an organ system‚ within an organism. All cells in the body‚ beginning with a zygote‚ contain the same DNA then go through cell growth and division‚ also called mitosis

EXECUTIVE SUMMARY The case “The Threat of Global Gridlock” by George Stalk highlights that the world is about to face a major crisis in transportation because of not meeting the demand of the global economy. The author believes that currently the threat has been masked away but it’s imminent and if the prerecession trend reappears it would be a serious problem with the lack of infrastructure and the rising prices of oil. According to him there are four basic means of transportation that are by truck‚ train

Electron Transport Chain The first step in the electron transport chain process is for the NADH2 produced during glycolysis‚ the intermediate step‚ and the citric acid cycle to be attracted to Complex I (FMN ·FeS)due to its high affinity for NADH2. This attraction pulls NADH2 to Complex I (NAD dehydrogenase) and the two electrons from H2 are pulled off by the FeS (ferrous sulfate) leaving two H+ ions and NAD+. These molecules repel each other and this results in the NAD+ being recycled
