Different factors may trigger adaptive radiations, but each is a response to an opportunity. Beetle radiations may have been triggered by adaptations for feeding on flowering plants.

The average medical oncologist salary grew by 2% in 2021, according to Medscape’s Despite the slow pay growth rate, given the chance, a large majority of medical oncologists say they would choose their specialty again. Sure, there are frustrations aplenty — from paperwork to insurance billing complications and more — but in general, medical oncologists who responded to the survey say they find their work rewarding and valuable. Overall job satisfaction is attributed largely to the positive relationships medical oncologists develop with both their patients and their patients’ families. As of 2021, the average medical oncology salary was the 10th highest among the specialties surveyed, with an average annual income of $411,000. This is about an $8,000 pay increase from 2020’s average of $403,000. Despite the rise in overall income, the picture looks slightly more troublesome when you look closer at the low growth rate of medical oncologists’ salary in comparison to physicians of other specialties. On average, the compensation of medical oncologist’s rose about 2% year over year compared to the prior year. Of the 29 specialties surveyed by Medscape, medical oncologist compensation increased, on average, much less than many other specialties. Around 32% of medical oncologists take on extra work to supplement their income — nearly on par with the rate of physicians in general, which sits at 36%. Of those who pursue side hustles, the majority of gigs are medical-related or medic...

They have have frequencies from 300 GHz to as low as 3 kHz, and corresponding wavelengths from 1 millimeter to 100 kilometers. Like all other electromagnetic waves, radio waves travel at the speed of light. Naturally occurring radio waves are made by lightning or by astronomical objects. Artificially generated radio waves are used for fixed and mobile radio communication, broadcasting, radar and other navigation systems, communications satellites, computer networks and innumerable other applications. Different frequencies of radio waves have different propagation characteristics in the Earth’s atmosphere—long waves may cover a part of the Earth very consistently, shorter waves can reflect off the ionosphere and travel around the worl...

• All objects give off thermal radiation • The hotter an object is, the more thermal radiation it emits • Thermal radiation is the part of the electromagnetic spectrum called infrared • Thermal radiation is the only way in which heat can travel through a vacuum • It is the way in which heat reaches us from the Sun through the vacuum of space • The colour of an object affects how good it is at emitting and absorbing thermal radiation: EXTENDED Thermal Equilibrium • As an object absorbs thermal radiation it will become hotter • As it gets hotter it will also emit more thermal radiation • The temperature of a body increases when the body absorbs radiation faster than it emits radiation • Eventually, an object will reach a point of constant temperature where it is absorbing radiation at the same rate as it is emitting radiation • At this point, the object will be in thermal equilibrium • If the rate at which an object receives energy is less than the rate at which it transfers energy away then the object will cool down • If the rate at which an object transfers energy away is less than the rate at which it receives energy then the object will heat up • The process will always move towards thermal equilibrium • The amount of thermal radiation emitted by an object depends on a number of factors: • The surface colour of the object (black = more radiation) • The texture of the surface (shiny surfaces = more radiation) • The surface area of the object (greater surface area = more a...

What is adaptive radiation and examples? Adaptive radiations are best exemplified in closely related groups that have evolved in a relatively short time. A striking example is the radiation, beginning in the Paleogene Period (beginning 66 million years ago), of basal mammalian stock into forms adapted to running, leaping, climbing, swimming, and flying. What is adaptive radiation explain with an example class 12? The process of evolution in which new species are produced from a single point and radiate in different directions is known as adaptive radiation. This is possible due to natural selection. One of the most common examples of adaptive radiation is that of Darwin’s finches which he found on Galapagos islands. Which best explains adaptive radiation? The encounter of a population to multiple of new or newly formed ecological niches is followed by diversification of ancestral line into different forms which in turn occupy a diverse ecological niche. The process is referred to as adaptive radiation. Thus, the correct answer is option C. What causes adaptive radiation? Adaptive radiations can be triggered by extrinsic factors such as the arise of new ecological opportunity via emergence of novel environments, and/or by intrinsic factors (‘key adaptive innovations’) that increase the availability of niches to a diversifying lineage [1–3, 7, 9]. Which of the following is an example of adaptive evolution? An example of adaptive evolution is the horse’s teeth. Its teeth are ...

Sometimes it travels in the form of a wave. That’s called electromagnetic radiation. Sometimes, it travels as a beam of fast-moving particles. That’s called particle radiation. Radiation is all around you! And it’s been there all your life. What is electromagnetic radiation? Electromagnetic radiation (EMR) consists of waves. The waves contain electric and magnetic energy. The electromagnetic spectrum (EMS) includes different types of energy waves. At one end of the spectrum, there are very low energy waves. Radio waves are an example of low energy waves. At the other end of the spectrum, there are very high energy waves. Gamma rays are an example of high energy waves. The electromagnetic spectrum. High-energy gamma rays are on the far left and low-energy radio waves are on the far right (Let's Talk Science using an image by Inductiveload [CC BY-SA 3.0] via Frequency and wavelength are used to describe EMR. Frequency refers to the number of waves per second. Wavelength refers to the distance between two adjacent wave peaks. The higher a wave’s...
