2 days ago · Tutankhamun (flourished 14th century bce) was a king of ancient Egypt (reigned c. 1333–24 bce), known chiefly for his intact tomb, KV 62 (tomb 62), discovered in the Valley of the Kings in 1922. During his reign, powerful advisers restored the traditional Egyptian religion and art, both of which had been set aside by his predecessor Akhenaten ...
It took eleven years to build the AutoSyringe, which he sold to Baxter International for $30 million. It was a defining moment for Kamen. He realized he loved working on many things and established DEKA (DEan KAmen). It is a state-of-the-art engineering lab, built with Kamen’s own funds, and staffed with three hundred engineers.
The legendary engineer says innovation = idea + scale. Dean Kamen is trying to create a runway for startups that will revolutionize biomanufacturing. Over the past 20 years, technological advances ...

The first letter of MRS GREN stands for movement. Although some organisms are pretty much immobile they will always have some level of self-powered movement, be it their entire body or particular body parts. Movement is evolutionarily important for organisms because it improves the chances of catching food or avoiding capture for both predator and ...
Respiration is the conversion of energy from carbohydrates and fats into energy that can be used by cells. In multi-cellular organisms, respiration is built around the breakdown of sugars with the use of oxygen. This produces carbon dioxide as a by-product. Some microorganisms, in areas where there is not very much oxygen, use other molecules, such...
Sensitivity refers to the way organisms respond to their environment. All organisms are able to sense changes in their environment and will respond accordingly. For example, barnacles will close their shells during low tide to prevent themselves from drying out, squid release ink when they feel threatened, and deer run away when they are startled b...
MRS GREN is sometimes known as MRS C GREN to recognize the importance of how living things control their internal environment. All living things have an internal environment inside their body and inside their cells. This internal environment needs to be maintained within certain conditions. Control refers to the way organisms are able to preserve t...
Growth is an irreversible change in mass. It is possible because respiration provides excess energy for organisms to use to grow. Excess energy can be used for the production of new cells and tissue which inevitably leads to the growth of an individual.
Reproduction is the creation of a living thing from an existing organism. The simplest form of reproduction is the division of one cell into two. For large, multi-cellular organisms reproduction is more complicated than a single division of a cell. Reproduction can occur sexually or asexually. Sexual reproduction requires two organisms. Asexual rep...
All organisms produce wastes that need to be removed. Normal functions in cells and tissues of organisms produce waste such as urine and dead cells. If waste products stay inside an organism they can become toxic. All organisms, therefore, have methods for removing waste products from their body. Excretion is the term used to define the removal of ...
Nutrition is the final component of MRS GREN. In order for organisms to survive they require food for energy and nutrients. Energy and nutrients are essential for growth, survival and reproduction. Many living things, such as animals, acquire nutrients by eating other organisms. Other organisms, such as plants, get food and nutrients from their env...
Movement – they move or change position. Respiration – they get energy from their food. Sensitivity – they respond to stimuli such as light, sound, temperature. Growth – they grow and develop. Reproduction – they have the ability to reproduce. Excretion – they get rid of waste products. Nutrition – they need food for energy.
