My bacterial plates did not grow any bacteria because our sterilization may have been eliminated. 2. LB/A/X+: There should have been a colony of bacteria with several splotches of blue because to new bacteria was created with the pBlu gene. LB/A/X-:There should have been bacterial growth because we put bacteria there and fed it. LB+:There should have been bacterial growth but no blue colonies because there was an anti-biotic acting against it.
The sexually transmissible disease gonorrhea has become increasingly resistant to treatment with antibiotics. What is the most likely scientific explanation? a) The gonorrhea bacteria learned to avoid antibiotics b) The gonorrhea bacteria changed their genes when they sensed antibiotics c) Antibiotic-sensitive gonorrhea bacteria died out, but antibiotic-resistant gonorrhea bacteria have flourished and persisted d) The antibiotic increased the mutation rate in the gonorrhea bacteria e) Both b and d 26. Which statement best describes the relationship between plants and animals on earth? a) Plants produce O2 and sugars from CO2 b) Animals produce CO2 and H2O from sugars and O2 c) Plants produce O2 and sugars and animals produce CO2 and H2O d) Animals produce O2 and sugars and plants produce CO2 and H2 27.
The Manhattan Project: The World’s Greatest Scientific Accomplishment Imagine a future where everything is run of nuclear power. Fossil fuels have been eliminated as a source of energy and the world’s environments has returned back to normal. All is well on Earth now. All that you have just imagined was only made possible by one event, The Manhattan Project. The Manhattan Project was the greatest scientific breakthrough of the twentieth century.
CJD can be grouped in three categories: sporadic disease, familial cases, and iatrogenic cases. The two different forms of CJD vary in multiple ways in that of the symptoms, treatment options, as well as how the disease is prevented. The pathogen that causes this deadly illness is a small protein called prion. This prion is a small proteinaceous infectious disease-causing agent that is the smallest infectious particle. Prions are neither fungal nor viral and they contain no genetic material, but they have been held responsible for a number of degenerative brain diseases including CJD.
Glenn Theodore Seaborg was born on April 19, 1912 and died on February 25, 1999 in Ishpeming, Michigan. He was an American scientist who had won the 1951 Nobel Prize in Chemistry for “discoveries in the chemistry of the transuranium elements”. He had also contributed to the discovery and isolation of ten other elements and also developed the actinide concept. The ten elements that he had co discovered were: Plutonium, Americium, Curium, Berkelium, Californium, Einsteinium, Fermium, Mendelevium, Nobelium and element 106, seaborgium was named after him in his honour while he was still alive. This was the first situation where an element was named after a person.
Najey Mcduffie March 12, 2012 Biology/ Pd. 4 Mr. McMillian Methods In Which Tapeworms Survive The immune system is made from cells, proteins, tissues, and organs, it is supposed to protect people from germs and microorganisms (2). It usually does a great job at protecting people, but somehow the immune system is unable to detect the tapeworm. Although tapeworms have no digestive system of their own, they acquire nutrients from partially digested food, through their skin as it goes through the person they inhabit. Tapeworms can grow to be at least twenty-two feet in somebody’s body.
Nowadays, there is a vaccine for the Black Plague but its takes awhile for it to become fully effective. There are drugs like antibiotics and sulphonamides that are used to treat it as well (“The Modern Day Black Death...”). Most people who contract the disease survive if they are given the right antibiotics in time. Good sanitation and cleanliness is a good way to prevent the bacteria from growing (“Plague”). During the time of the Plague, there was no medicine that could cure or help alleviate the disease.
Shaheer Ashan Inventions during the 1900s There have been many great inventions during the 1900s that have impacted many people. They have changed people’s lives and made them easier. Inventions such as the airplane, the first non-leaking ballpoint pen, easy-to-use Band-Aid, Crayons, the crossword puzzle, and the disposable diaper. These inventions have helped made things easier for people and impacted their lives greatly. People from the past have also improved these inventions.
The agar plate with the –pGLO LB / amp add no bacteria living in it because it wasn’t ampicillin resistant. But on the other hand the +pGLO LB/amp had a colonies of bacteria because when there is the pGLO plasmid it makes the e-coli bacteria ampicillin resistant so that is the reason why there are colonies of bacteria on the agar plate. For the last agar plate left the +pGLO LB/amp/ara this agar plate is the one that genetically transformed this is the one that could glow under the UV light <Fig 3 bottom right>. The reason that it glowed is because of the arabinose gene on the agar plate, that arabinose gene is the gene that triggers the GFP gene to express
He saw that the microorganism was disappearing. Fleming called the fluid the world’s first antibiotic Penicillin. Unfortunately nobody was making use of his antibiotic. Howard Flory and Ernst Chain skilled chemists did many studies to use penicillin effectively on humans. So Penicillium has become a drug of a choice for many infections such as pneumonia, syphilis, blood poisoning and strep throat.
