All symptomatic males tested had a forty-seventh chromosome in their cells. Though this may seem like a minimal change beyond the norm, these are the instructions for how the body should develop and if anything is thrown off balance it could result in extreme anomalies. During a process called meiosis, a type of cell division, a sperm or egg may experience a critical error called nondisjunction where the sex chromosomes do not split correctly…

(alkyl-PACs) to elucidate the mechanism of neurotoxicity using human neuroblastoma cells. The lethal concentrations (LC10 & LC20) were found at around 10 µM and 40 µM after 24 hours exposer to SK-N-SH cells. Exposed differentiated neuronal cells showed significant dose-dependent increase levels of reactive oxygen species (ROS), even at with sub-lethal concentration (DBT, and…

Name and discuss six functions of the integumentary system. * Protection- chemical (low pH secretions & bacterial activity), physical/mechanical (keratin &glycolipids block most water & water soluble substances), biological barriers (dendritic cells, macrophages & DNA). * Body temperature regulation- helps keep body temperature at a normal level. * Cutaneous sensations- sense touch, pain, and temperature. * Metabolic functions- synthesis of Vitamin D, chemical conversion of…

P5 List of all cell features and functions: • Nucleus • Cytoplasm • Cell membrane • Mitochondria • Ribosomes • Cell wall (Plant Cell) • Endoplasmic Reticulum (smooth & rough) • Lysosome • Golgi Apparatus/body • Nucleolus • Vesicles A nucleus is like the brain of the cell, it is a large oval which controls the activities of the cell and the nucleus also contains genetic material (DNA). The nucleus also contains hereditary information. Most chemical processes and reactions, which are…

no unknown contaminants such as bacteria or cells can compromise the procedures of the experiment (examples of such techniques include wearing the proper personal protective equipment, cleaning important surfaces with ethanol, and pipetting liquids in…

A genetically altered baby is something some people have only dreamed about, but now, it has become a reality. Scientist have discovered a way to alter human genetic traits and produce the perfect offspring. Some traits scientists have tried to alter include sex, eye color, and height, but it is still in the experimenting stage and should be possible within the next few years. Add more. Creating genetically altered babies should be prohibited. Genetically altering babies is still in the…

Eubacteria best live in moderate temperatures, low salts and where there is a plethora of sunlight or organic compounds (Ladiges, 2010). The main differentiating structure of eubacteria is that it has peptidoglycan in its cell walls, has one RNA polymerase and has the ability to form spores that can live many years but remain inactive until its environment is just right for it to activate itself. They are similar to eukaryotes in that they also have ester linked lipids,…

Most importantly, we have tools like stem cells to help science advance many medical researches that could lead to break through in medicine. I know that anti-abortion groups will want us to believe that abortion is wrong and evil, we should disregard their arguments because they are solely based…

many other problems with the lung, pancreas, and many other parts in your body. The disease is caused by a defective gene called the CFTR gene. These genes code to produce CFTR proteins which are used to transport water and particles into or out of cells. This helps maintain a healthy balance of water and salt in your body. However in people with Cystic Fibrosis, these genes cannot properly code proteins, causing very thick mucus. This can cause blockage in the lungs and digestive system. Cystic…

Introduction Designer babies used to be something that was only in science fiction books, but now, scientists are very close to being able to create them. There are many unknowns with designer babies such as will they be used to create healthier babies only, or will everything be about making the “perfect” looking baby. That is just one example of many. However, what could possibly be one of the most harmful consequences of designer babies is a reduced gene pool that could be caused by the…
