Much of the ocean has still been unexplored, but the parts that we have explored have allowed us to see something nearly unbelievable for the first time: fish that naturally light up! In fact, many different types of creatures that live in the water light up: squid, eel, jellyfish, which can be seen to the right in figure one, and many various species of fish have the ability to do such. The ability, called bioluminescence, is defined as “ the emission of light from living organisms”, according…
The Sun and Our Star - Have you ever questioned as to how and why we are able to dry our clothes in the summer, and to be able to heat food and treat our water? - This all thanks to the sun - Without the sun, we all would be dead, it gives us light, heat and energy to heat up the Earth - Most of the energy stays inside of the sun because of its gravitational pull, and all small amounts leave the surface in the form of radiant energy Type of star: Age: Yellow dwarf 4.5 Billion Years…
Nuclear radiation effects ERT term 4 With the depletion of fossil fuels and their harmful carbon dioxide emission, nuclear power is an increasing energy source. World-wide around 11.5% of energy is nuclear and in countries like France it’s 76.9% of their power source. With nuclear power being a renewable and relatively clean source of energy, nuclear power plants are being built all over the world. But despite the environmentally friendly aspects of nuclear power, when nuclear waste is not…
In experiment 1 there were five cuvettes of decreasing concentrations from the initial 0.01 mg/ml concentration of Fast Green solution (cuvette 1). The diluted concentration of cuvettes #2 through #5 were calculated using the dilution formula, C1V1 = C2V2 ; the calculations for the dilute concentrations are in Results section. The concentration for each tube were as follows: 0.015 mg/ml for tube 1, 0.0075 mg/ml for tube 2, 0.00375 mg/ml for tube 3, 0.001875 mg/ml for tube 4, and 0.000935 mg/ml…
Spectrophotometry is a method in which organic and inorganic substances are identified or characterized by the use of electromagnetic radiation. Electromagnetic radiation not only includes light (or photons), but thermal energy as well. While the electromagnetic spectrum consists of wavelengths between gamma radiation and the Far IR, most spectrophotometric methods rely on the UV and visible region. In order to use spectrophotometric methods, the sample being analyzed must be able to absorb the…
Urinary incontinence is when you urinate when you do not mean to (involuntarily). What are the causes? There are many possible causes of urinary incontinence, including: Medicines. Infections. Enlargement of the prostate in men. The prostate is a gland near the bladder. When it gets too big, it can cause overflow of urine from the bladder. Surgery. Diseases that affect the nerves or spinal cord (neurological diseases). Emotional factors. What increases the risk? What are the signs or symptoms?…
Many people today have a disease called Cancer, it depends when the doctors find it, it could be big or it could be small. Doctor’s now have the equipment to surgically remove cancer. Sometime’s doctors have to shrink the tumor depending how big it is in order to remove it. Kids can get it easily get cancer there are kids all over the world are getting sick with cancer. I picked this disease because it isn’t something fun to have. Cancer is when cells divide without control and invade other…
Cancer is a disease affecting the world and the rise in treatments with drugs is just one way of delaying the process of the disease as well as improving the quality of life for the patient. Henceforth Amsacrine is one to watch out for due to its specific mode of action. Reference. Amsacrine has an acridine chromophore with an amine at the 9 position (fig 1.) used in the treatment of some types of lymphoma or acute adult leukaemia [5]. It can also be known as Amsidine or m-AMSA [1]. Lymphoma…
The disease I chose for this topic is Lymphedema. “Lymphedema refers to swelling that generally occurs in one of your arms or legs. Sometimes both arms or both legs swell. Lymphedema is most commonly caused by the removal of or damage to your lymph nodes as a part of cancer treatment. It results from a blockage in your lymphatic system”(Mayo Clinic Research) The word Lymphedema is broken down into two words, Lymph that is the colorless fluid in your body. Edema, which means swelling. Lymphedema…
During the microscope lab, my partner and I learned how to properly use a microscope, calculate the field of view, and view and prepare slides. Microscopes are instruments used to view very small objects that cannot be seen with the naked eye. We found that microscopes have many different parts to them, including the diaphragm, ocular lens, and objective lenses. There are three powers of magnification, scanning power (4x), low power (10x), and high power (40x). To find the total magnification,…
