What else can I help you with?
Linkage studies refer to tracing a particular trait within a family does this mean that twin and adoption studies are a type of linkage study?
No. Linkage studies use markers to identify chromosomal regions that may be linked to disease. Twin and adoption studies establish heritability and thus the genetic basis of a disease, not which chromosome or chromosomal region may be implicated. For this reason they are called genetic epidemiological studies.
What are the two main types of data a scientist collect?
Data will be either qualitative (non numerical description) or quantative (numerical values assigned to a property). To give you an example, a meterologist may describe the sky on a particular day as cloudy (qualitative) with a 5 mile per hour wind (quantative). Studies can be classified as experimental studies or observational studies. The experimental study means that the scientist is able to treat or alter in some way the population. Medical studies of drugs frequently conduct experimental studies and collect experimental data. Observational studies, we collect data without altering the population. A good example is astronomical studies, where it is impossible to alter the population. Scientific studies need to be thorough investigations relying on good data and sufficient quantity of data in order to reach conclusions.

How does the US environmental agency classify carcinogens?
A carcinogen is an agent that can produce cancer (a malignant growth or tumor that spreads throughout the body, destroying tissue). The EPA (Environmental Protection Agency) classifies chemical and physical substances according to their toxicity to humans.EPA classification system for carcinogensGroup A. Humans CarcinogensThis classification indicates that there is sufficient evidence from epidemiological studies to support a cause and effect relationship between the substance and cancer.Group B. Probable Human CarcinogenB: Substances are classified as B carcinogens on the basis of sufficient evidence from animal studies, and limited evidence from epidemiological studies.B: Substances are classified as B carcinogens on the basis of sufficient evidence from animal studies, with inadequate or nonexistent epidemiological data.Group C. Possible Human CarcinogenFor this classification, there is limited evidence of carcinogenicity from animal studies and no epidemiological data.Group D. Not Classifiable As To Human CarcinogenicityThe data from human epidemiological and animal studies are inadequate or completely lacking, so no assessment as to the substance's cancer-causing hazard is possible.Group E. Evidence Of Noncarcinogenicity For HumansSubstances in this category have tested negative in at least two adequate (as defined by the EPA) animal cancer tests in different species and in adequate epidemiological and animal studies. Classification in group E is based on available evidence; substances Amy prove to be carcinogenic under certain conditions.
When was Spatiotemporal Epidemiological Modeler created?
Spatiotemporal Epidemiological Modeler was created in 2006.
What type of research studies populations and is often used to search for correlations between dietary habits and disease incidence?
Epidemiological research studies populations and is frequently used to investigate correlations between dietary habits and disease incidence. This type of research often involves analyzing data from large groups of people to identify patterns and associations between various factors such as diet and disease risk.
What types of education is offered in Romania?
