Adaptive radiation Part of a series on. In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges, or opens new environmental niches.

What Is Electromagnetic Radiation? Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small portion of the EM spectrum, which contains a broad range of electromagnetic wavelengths.

How I Got Pregnant in 1 Cycle (â¦..at the age of 34) I mean, I’m 34 1/2 and the internet & doctors act like that’s ancient. They said “at that age,” it could take up to 2 years. And while I didn’t think it would take that long, I didn’t think it would take a matter of weeks. So here’s how it happened. First I need to give a disclaimer.

What Is Electromagnetic Radiation? The EM spectrum. EM radiation spans an enormous range of wavelengths and frequencies. This range is known as the electromagnetic spectrum. The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency.The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.aves and fields. EM radiation is created when an atomic particle, such as an electron, is accelerated by an electric field, causing it to move. The movement produces oscillating electric and magnetic fields, which travel at right angles to each other in a bundle of light energy called a photon.

Synchrotron radiation Synchrotron radiation (also known as magnetobremsstrahlung radiation) is the electromagnetic radiation emitted when charged particles are accelerated radially, i.e., when they are subject to an acceleration perpendicular to their velocity (a ⊥ v). It is produced, for example, in synchrotrons using bending magnets, undulators and/or wigglers.

Unit2/Obj1 Radiation Responses An early effect is a radiation response in humans within a few days to months due to a substantial dose. These early effects are described as deterministic and they exhibit increasing severity with increasing radiation dose, also there is usually a dose threshold. Genetic effects are late effects.

The Electromagnetic Spectrum Infrared radiation is popularly known as heat radiation , but light and electromagnetic waves of any frequency will heat surfaces that absorb them. Infrared light from the Sun accounts for 49% of the heating of Earth, with the rest being caused by visible light that is absorbed then re-radiated at longer wavelengths.

Adaptive immune system The adaptive immune system is one of the two main immunity strategies found in vertebrates (the other being the innate immune system). Adaptive immunity creates immunological memory after an initial response to a specific pathogen, leads to an enhanced response to subsequent encounters with that pathogen.his process of acquired immunity is the basis of vaccination. Like the innate system, the adaptive system includes both humoral immunity components and cell-mediated immunity components. Unlike the innate immune system, the adaptive immune system is highly specific to a specific pathogen.

Genetic recombination V(D)J recombination in organisms with an adaptive immune system is a type of site-specific genetic recombination that helps immune cells rapidly diversify to recognize and adapt to new pathogens.rom Wikipedia, the free encyclopedia. A current model of meiotic recombination, initiated by a double-strand break or gap, followed by pairing with an homologous chromosome and strand invasion to initiate the recombinational repair process.

What is Electromagnetic Radiation? Electromagnetic radiation is a term used to describe a stream of energy-bearing particles that travels outward from an electromagnetic source.The energy in these streams can vary extensively in power, and is measured by the electromagnetic spectrum.adio telescopes detect radio waves, a form of electromagnetic radiation, from space. Rainbows contain the colors of the visible spectrum. Cell phones create electromagnetic radiation. The sun releases ultraviolet rays that may cause sunburn and possibly skin cancer if overexposure occurs.

Adaptive Radiation: Darwin's Finches This process in which one species gives rise to multiple species that exploit different niches is called adaptive radiation. The ecological niches exert the selection pressures that push the populations in various directions.

Introduction to Immunology Tutorial Adaptive immunity refers to antigen-specific immune response. The adaptive immune response is more complex than the innate. The antigen first must be processed and recognized. Once an antigen has been recognized, the adaptive immune system creates an army of immune cells specifically designed to attack that antigen.Adaptive immunity also includes a memory that makes future responses against a specific antigen more efficient.he adaptive immune response is more complex than the innate.

Overview Radiation therapy is a type of cancer treatment that uses beams of intense energy to kill cancer cells. Radiation therapy most often gets its power from X-rays, but the power can also come from protons or other types of energy. The term radiation therapy most often refers to external beam radiation therapy. During this type of radiation, the high-energy beams come from a machine outside of your body that aims the beams at a precise point on your body. During a different type of radiation treatment called brachytherapy (brak-e-THER-uh-pee), radiation is placed inside your body.

Radiation and Health Radiation is energy that moves through space or matter at a very high speed. This energy can be in the form of particles, such as alpha or beta particles, which are emitted from radioactive materials, or waves such as light, heat, radiowaves, microwaves, x-rays and gamma rays.

Electromagnetic radiation Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields that propagate at the speed of light through a vacuum. The oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. The wavefront of electromagnetic waves emitted from a point source (such as a lightbulb) is a sphere.

biological aspects of radiation A. Relative biologic effectiveness Relative biologic effectiveness (RBE) compares the biological effect of a 250 keV x ray with other radiations. For example, some radiation might produce twice the effect that a 250 keV x ray would.
