answer. b) Stem cells. A relative of a friend of yours had a spinal cord injury after a bad car accident. The medical team has decided that this patient is a good candidate for a clinical trial using stem cell therapy. Your friend has not had a biology course since high school‚ so you are going to write for him or her a two-page discussion of stem cell information. In your discussion‚ include a description of the biology of stem cells‚ and explain how these cells are unique in their

Stem cells are pluripotent cells present in all living organisms. These cells can differentiate into any type of cell‚ including nerves and cardiac muscle. The scientific community is very excited about the possibility of these undifferentiated cells being used to treat conditions such as spinal cord injuries‚ diabetes‚ and cancer. Despite the enormous potential for medical advancements‚ controversy surrounds the sources and methods of acquiring stem cells and the possible improper uses of the knowledge

FUEL CELL CARS Fuel Cell cars are a major part of the fleet of Zero-Emission Vehicles. The fuel cells are fueled with pure hydrogen and hence they are considered to be zero emission vehicles. Fuel cells have been used on spacecraft for many years to power electric equipment. These are fueled with liquid hydrogen from the spacecraft ’s rocket fuel tanks. Basic Mechanics Fuel cell vehicles turn hydrogen fuel and oxygen into electricity. The electricity then powers an electric motor‚ just like

Cell Membrane Structure Phospholipids are arranged in to layers‚ called the bilayer. They only have 2 fatty acids‚ this is because the third fatty acid is replaced by a negatively charged phosphate group. The phosphate heads are polar‚ in other words attracted to water‚ therefore they are hydrophilic. The lipid tails are non-popular as they’re not attracted to water and therefore known as hydrophobic. When phospholipids are added to the water‚ they rearrange themselves so that the hydrophilic heads

ABSTRACT Stem cells have offered much hope by promising to greatly extend the numbers and range of patients who could benefit from transplants‚ and to provide cell replacement therapy to treat debilitating diseases such as diabetes‚ Parkinson ’s and Huntington ’s disease. The issue of stem cell research is politically charged‚ prompting biologists to begin engaging in ethical debates‚ Stem cell research offers great promise for understanding basic mechanisms of human development and differentiation

Dangers of Cell Phones I am sure that most of you own cell phones and that you can’t leave your home without it. And that all of you think of cell phones as one of the most useful devices of our time. Despite all that‚ have you ever considered dangers of using cell phones or thought about the harmful effects of the microwave radiations? (Pause) Just 10 years ago‚ cordless telephones were something used only by big businesses and privileged persons‚ but Nowadays; it seems that every kid

Nucleus- The nucleus is the control center of the cell. This is where DNA is contained. This is like the town hall or the mayor’s office because it is the control center of a town. The nucleus uses DNA like a city uses blueprints to direct the production of protein. Nucleolus- The nucleolus is where ribosome is made and is rich in RNA content. It is located inside the nucleus. A mayor is like this because the mayor makes everything in the town happen. He also works from the town hall‚ or works

Stem Cell Research NAME American Military University Abstract This Paper explores the fine lines of study regarding Stem Cell Research. We’ll discuss the Stem Cell basics to include the importance for use‚ the effects of repairing the body‚ and the possible benefits to curing diseases and illnesses. As well shed light on the Ethics regarding the use of Stem Cells. To include but not limited to the debate regarding the procedure is immorally wrong (ethically speaking)‚ the death of

Question: How does mitosis produce new cells‚ and how is mitosis the same and different? Materials: - Compound microscope - Alliums root slide - Whitefish embryo slide - Power supply Procedure: Refer to page 48 and 49 in the textbook. Results: See attached sheet for drawings of my results. Discussion: Analyze and interpret question 1 and 2 on page 49. 1. The cells in the root tip region of the alliums differ quite a bit from the cells that are found deeper in the root. First

Eukaryotic vs. Prokaryotic cells Prompt: Describe the similarities and differences between Prokaryotic and Eukaryotic cells. All organisms are made of cells. The cell is the simplest collection of matter that can be alive. Cells are the basic structural and functional units of every organism. Cells fall into two distinct types: Prokaryotic and Eukaryotic. While Prokaryotic and Eukaryotic cells are similar in that both types of cells are bounded by a plasma membrane‚ all contain cytosol‚ and all
