Stem cells are unique because they have the ability to generate new cells of any kind during early life and growth. There are about 200 different types of cells in the body; such as muscle‚ skin and brain cells. Most of these cells have to be repaired or replaced once in a while. For example our taste buds are replaced every 10 days‚ skin cells every couple of weeks and liver cells every 300-500 days. Stem cells serve as an internal repair system dividing essentially without limit to replenish

an ostrich egg is the largest of all eggs‚ it is the smallest egg in relation to the size of the bird. * The Ostrich egg will weigh 1600 gm and is equivalent to 2 dozen chicken eggs. * An Ostrich Hen can lay 40 -100 eggs per year‚ averaging about 60 eggs per year. * Ostrich eggs hatch in 42 days. * An Ostrich chick grows one foot taller each month until it is 7-8 months old. * Females sit on eggs by day; males sit on eggs by night. * To soft boil a fresh egg would take

Transformation Transformation is about change which the change goes to the depths of what an individual feels and will affect what people feel about such society‚ country or organization‚ what they do in the organization and maybe what they hold dear to life. Organizational transformation is more than just changing the way business is done. It is about changing the organizational culture in one or more ways‚ it is not just about passing out orders and implementing policies in a country as we had

October 2014 Cell Division Mitosis Abstract Mitosis and Meiosis: Cells can be divided in unicellular organisms or in multi-cellular organisms. DNA controls the cell division. Bacteria reproduce by a process called binary fission. Bacteria have one chromosome that’s attached to the cell membrane. The chromosome replicates and the two copies separate as the cell grows. Over a period of time this one cell makes two cells. Eukaryotes do the process of mitosis. In mitosis‚ each daughter cell gets about

protect and egg‚ comparable to how real cars protect us. If you built a car that did not protect the egg‚ it is comparable to you having been in a fatal car crash. II. Variables: * With the building of our cars‚ we were measuring the mass of the egg‚ mass of the car‚ time for it to go down the track‚ and the width so that it would fit down the track. The variable that affects our cars the most is the mass. If your car weighs to little‚ it will go at high speeds and the egg will most likely

Abstract The objective of this study was to observe and record the effects that exercise has on cardiovascular functions such as mean blood pressure‚ cardiac output‚ and total peripheral resistance by comparing each numerical function’s numerical data before and after exercise. Before exercise‚ the mean blood pressure (MPB) was 84.03 mmHg with a standard deviation of 10.3. After exercise‚ MBP was 92.19 with a standard deviation of 10.5. The cardiac output (CO) before exercise was 5.45 Liters/minute

pluripotent stem (IPS) cells differ from those currently in place for human embryonic stem (ES) cells. An IPS cell is created artificially from skin‚ fat and fibroblasts by reprogramming patient ’s own cells. Scientists believe IPS cells to be a promising source for treating diseases. An ES cell is created by destroying an embryo. Other scientists think ES cells will also be a promising source because it is composed of your own DNA‚ so the immune system won ’t reject the cell. While scientists would

Plan:- Independent Variable- Temperature is what I will be changing in the experiment. I want to find out what effect temperature has on the permeability of a cell membrane. Controlling other Variables- I will use measures to ensure that everything stays the same in my test to gain the best and most reliable results possible - Same volume of water that I put the beetroot into after heating. - The beetroot I use will be the same size each time‚ I will ensure this using a cork borer. - The beetroot
