This experiment helped us understand more about pill bugs and it's supported our hypothesis that the pill bugs would prefer the moist environment over the dry environment. The only thing we failed to state the fact that the pill bugs would not prefer to be in the dry area, this is shown by how much they wanted to get out of the new environment we placed them in. Our test result shows that the pill bugs prefer the moist area over the dry area more and also a dark area over a place with light. Based

The University of Central Florida campus celebrated science on Friday as students from kindergarten through 12th grade crowded around exhibit tables, launched bottle rockets, played with robots and made their own slime. Around 1,400 students and their teachers came to UCF to learn about science, technology, engineering and math for STEM Day, according to Renee Sackett, the event’s coordinator. The goal, she said, was to get kids excited about STEM and inspire them to pursue careers in STEM fields

meanings. For some individuals, it denotes an appreciation of good literature, art, music, and food. For a biologist, it is much more likely to mean a colony of bacteria or some sort of microorganisms growing in a nutrient medium in a laboratory Petri dish. However, for anthropologists and other behavioral scientists, culture is the full range of learned human behavior patterns (O'neil, 2006). The term was first used in this way by the pioneer English Anthropologist Edward B. Tylor in his book

oven. D. We use various forms of media for cultures including nutrient broth, agar slant, agar stab, and agar dishes. Nutrient broth is a liquid medium that does not use agar and is used for inoculum preparation. Agar dishes are sterile covered petri dishes filled with a solid medium in them, the agar, and used to test, grow and culture bacteria. For the agar slant, the liquid agar is put into a tube in such a way that it will harden at a slant. They are better used for storage. An agar stab is

\While the history of cloning is relatively short, understanding how cloning came about is important to understanding the greater debate surrounding cloning. At the Roslin Institute in Edinburgh, Scotland, in July 1996, scientists produced the first animal cloned from an adult cell. Dolly the sheep was born early in 1997, shocking the scientific community and the world. Dolly was created through a process called cell nuclear replacement. A mammary cell of a six-year-old white Welsh Mountain sheep

Raymond Swayze Comp II In 2004, 7,266 blood stem cell donations and 1,126 cord blood units were provided in desperate need. More than 50,000 patients worldwide have received blood stem cells from an unrelated donor(WMDA). Different types of stem cells have the ability to heal many types of damaged human tissue. There’s only one type of stem cell that can almost guarantee it can fix any kind of tissue. This is known at the embryonic stem cell. The only way to obtain these cells is by taking them

When asked what I am most curious about, the first thing that enters my mind is genetic engineering. I would like to know more about how this technology began and what its original purpose was. Also, I long to discover how this technology is being expanded, what purpose it is it being aimed towards, and how it is due to develop in the near future. I have read that Francis Bacon was the first scientist to allude to the future field of genetic engineering and terminator technology. Although terminator

both a whole organism and an individual organ, is a sign of potential for the scientific community. Cloning a whole organism can be done by two methods. The first, artificial embryo twinning, involves separated an embryo into individual cells in a Petri dish. These embryos are placed in a surrogate mother for their development and are identical because they all had the same fertilized egg. The other method of entire organism cloning is called somatic cell nuclear transfer or SCNT. SCNT involves isolating
