Ask A Biologist is a pre-kindergarten through high school program dedicated to answering questions from students, their teachers, and parents. The program's primary focus is to connect students and teachers with working scientists through a question-and-answer web e-mail form.
A bioassay is a biochemical test to estimate the potency of a sample compound. Usually this potency can only be measured relative to a standard compound. [3] [1] A typical bioassay involves a stimulus (ex. drugs) applied to a subject (ex. animals, tissues, plants). The corresponding response (ex. death) of the subject is thereby triggered and ...
Tests of necessity, among which are methods of lesioning or gene knockout, and tests of sufficiency, among which are methods of isolation or discrete stimulation of factors, have become important in current-day experimental designs, and application of these tests have led to a number of notable discoveries and findings in the biological sciences.
Experimental biology is the set of approaches in the field of biology concerned with the conduction of experiments to investigate and understand biological phenomena. The term is opposed to theoretical biology which is concerned with the mathematical modelling and abstractions of the biological systems.
The laboratory is a foundational example of hands-on, activity-based learning. In the laboratory, students use materials to observe scientific concepts and phenomena. The laboratory in science education can include multiple different phases. These phases include planning and design, performance, and analysis and interpretation.
The following standardized tests are designed and/or administered by state education agencies and/or local school districts in order to measure academic achievement across multiple grade levels in elementary, middle and senior high school, as well as for high school graduation examinations to measure proficiency for high school graduation.
Over the years, various drug czars from both political parties have consulted her at Rockefeller University in New York City, where she is a professor and head of the Laboratory of the Biology of Addictive Diseases. According to Kreek, there’s no controversy over how opiate addiction acts upon the brain.
Field experiments offer researchers a way to test theories and answer questions with higher external validity because they simulate real-world occurrences. [6] Some researchers argue that field experiments are a better guard against potential bias and biased estimators. As well, field experiments can act as benchmarks for comparing ...
