How does a hypothesis differ from theory?
A theory is a an possible explanation for why a phenomenon occurs, a hypothesis is a tangible measurable statement of prediction for a research project which can be scientifically supported or refuted. Example: Theory: it is possible that cigarettes cause cancer due to the chemicals added to the cigarettes, which are inhaled into the lungs and subsequently ruin the tiny airsacks within the lungs. Over time this may lead to cancerous growths. Hypothesis: People who smoke 2 packs of cigarettes a day for 30 years have an increased risk of developing skin cancer later in life, when compared to non smokers.
When culturing cells why do researchers prefer cancer cells over healthy cells extracted from an organism?
Cancer cells divide quickly and almost indefinitely. This makes them easy to grow in a dish while tissue culture with healthy cells is almost impossible.
What is the disorder in which some of the bodys cells grow uncontrollably?
The disease is cancer
Where are cancer cells found in the body?
Cancer cells are found in the affected organ or tissue. There are several types of cancer depending on anatomical location within the body like skin cancer, blood cancer, lung cancer etc. Also it depends on how a particular type of cancer spreads like the Carcinomas spread through lymph so the cancer cells can be found at lymph nodes whereas, the sarcomas spread through blood. Another noteworthy thing is that in the later stages of cancer it can spread to a distant organ and start a secondary cancer in the new location.
What is colan cancer?

What word means an educated guess?
An educated guess, at least in a scientific context, is a hypothesis. An estimate is a word for an educated guess about facts or figures, or how much a job may cost.Examples:"My hypothesis is that this new chemical can cause cancer.""I estimate that the building over there is roughly 150 feet high.""The estimate from the mechanic about the work needed on the car is $300."
What is a hypothesis that has been tested over and over?
a cure for cancer
When was SHARE cancer support created?
SHARE cancer support was created in 1976.
What are the critical elements of design in the investigation?
In a scientific experiment, the following design elements are vital: 1. A falsifiable hypothesis - the question you are trying to answer (the hypothesis) must have a definitive "true" result and a definitive "false" result. For instance, a hypothesis may read "Drug X results in longer remission periods for cancer patients." The null hypothesis to this (the "hypothesis is false" result) is "Drug X does not result in longer remission periods for cancer patients." 2. The study must be statistically valid. When designing an experiment, you need to have enough data to conclude a "true hypothesis" result is real and not just because you got lucky and by chance found data to support a "true hypothesis" result. This will dictate the number of subjects studied as well as a general time frame for the study. 3. The data collection methods must be validated. If you are testing for cancer remission in breast cancer patients, you would use lymph node biopsies or mammograms to look for evidence of cancer resurgence; you would not use a blood chemistry test as the test wouldn't find the cancer even if it was there.
What are some cancer support groups?
Some cancer support groups are available through the Macmillan Cancer website. Other cancer support groups are CANCERactive, Ovacome UK and Crazy Hats.
What is the null hypothesis of a one way ANOVA What is the alternate hypothesis?
When writing hypotheses the null hypothesis is generally the hypothesis stating that there will be no significant difference between the variables you are testing. An alternate hypothesis would be a hypothesis suggesting that the results will be anything other than not significant. For example if you were testing three concentrations (low, medium, and high) of a type of medication on cancer cells, then one example of an alternate hypothesis would be that the medium concentration would decrease the number of viable cancer cells.
Where can information on breast cancer support groups be obtained from?
