    Using other people’s research or ideas without giving them due credit is plagiarism.

    Since Bib Me™ makes it easy to create citations, build bibliographies and acknowledge other people’s work, there is no excuse to plagiarize.

    Don’t be a thief—save your grade, use Bib Me™ and give credit to those who deserve it!

    With the advent of modern biotechnology, researchers have been able to determine the actual sequence of the roughly three billion bases of DNA (A, T, C, G) that make up the human genome.

    This process involves measuring the rate of decay of radioactive isotopes.

    Radioactive substances give off protons (positive particles) and neutrons (neutral particles) at a steady rate.

    In this case, the uranium is called the parent and the lead is called the daughter element.

    This is a slide and worksheet for radioactive dating and half life activity.

    Absolute-age dating is way for scientists to tell the exact age of a rock, fossil, or other object. Isotopes are atoms of the same element that have the same chemical properties. These isotopes are found in igneous and metamorphic rocks.

    Eventually, these substances change into different elements. For example, an isotope of uranium, U-238, will eventually decay into an isotope of lead.

    This change, over time, is called radioactive decay.

    All created kinds exhibit a certain amount of genetic variability within their grouping while still maintaining specific genetic boundaries.

    In other words, one kind does not change into another, either in the fossil record or in observations of living organisms.
