As soon as the blood was introduced into the solvent‚ we shook the mixture to ensure the process would happen correctly and efficiently. Results Table I gives the values in seconds of how long all 11 solutes took to hemolysis in seconds. Each molecule has been tested by 7 separate groups as to have a variation

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue‚ salivary glands‚ pancreas‚ liver‚ and gallbladder).[1] In this system‚ the process of digestion has many stages‚ the first of which starts in the mouth. Digestion involves the breakdown of food into smaller and smaller components‚ until they can be absorbed and assimilated into the body. Chewing‚ in which food is mixed with saliva begins the process of digestion. This produces a bolus

How does the amount of dissolved NaCl in water effect the volume of one drop? Aim: This experiment plans to measure the volume of one drop of water and compare it the volume of one drop of sodium chloride solution. What will be attempted by this experiment is to measure the volume of one drop of distilled water by measuring a control and comparing it the volume of one drop of distilled water with dissolved NaCl. This will be done by using a burette for dropping the distilled water and a electrolyte

roles of mitotic cell division‚ meiosis‚ and fertilization in the human life cycle. Mitosis allows for growth and repair from the fertilized egg to the adult. In reproductively mature individuals‚ meiosis creates gametes with half the genetic material. The male gamete then fertilizes the female gamete during sexual reproduction‚ forming a zygote with a full set of genetic material. 2. Why are both cell division and apoptosis necessary for the development of an organism? Cell division is needed

Damage of Beet Cell Membranes Caused by Different Temperatures Resulting in Betacyanin Leakage By: Trevor Sandum‚ Lab 2‚ March 9‚ 2013 Introduction: A red pigment called Betacyanin located in the vacuole of the beet cells is released when the membrane is damaged (Danyk‚ 2013). The membrane is necessary for sustainability of the cell’s life‚ it separates the cell from the outside environment‚ and is responsible for diffusion‚ exocytosis and endocytosis‚ and transport. It

how the does the skin act as a barrier The skin is cleverly designed to perform in helping the skin acting as a physical‚ chemical and physical barrier for the body. The physical barrier acts as a protective cover to protect us from the environment i.e. pathogens‚ physical abrasions and radiation from the sun. Yet it is known to be one of the largest organs in the body in weight and in surface area. In adults‚ the skin makes up 16% of body weight and the skin covers an area of about 2 square meters

main character‚ Kate‚ is very interested in science and the three titles are a metaphor for her state of mind throughout the book. The first section‚ Solid‚ shows how Kate is a stable and strong person. The next section‚ Liquid‚ is a time where Kate’s life is very inconsistent and she is unsure about herself. The last section‚ Gas‚ shows how Kate has accepted her fate and tries to help everyone she can. A solid is hard‚ strong‚ and stable in shape. A person who is solid can be described as having stable
