How do waves interact with different materials?
Flauer [41]

Answer:

Waves interact with matter in several ways. The interactions occur when waves pass from one medium to another. Besides bouncing back like an echo, waves may bend or spread out when they strike a new medium. These three ways that waves may interact with matter are called reflection, refraction, and diffraction.

how do scientists use fossil comparative anatomy and branching diagrams to explain the evolution of organism
Mnenie [13.5K]

Hi there!

In order to do fossil comparative anatomy and branching diagrams to explain the evolution of organism, scientists use <u>radiocarbonation </u><u>method</u>.

Explanation:

Carbon-14 can combine with oxygen in the atmosphere to create carbon dioxide, which is then absorbed by plants and makes its way through the food chain. The amount of carbon-14 in living plants and animals matches the amount in the atmosphere, but when plants and animals die, they no longer absorb carbon-14.

Because radiocarbon has a known rate of decay, the scientists can now determine about how long it has been since the plant or animal was alive. <u>The lower the amount of radiocarbon, the older the object.</u>

(Sometimes, C-12 is also used)

RideAnS [48]

b. Natural selection is an example of the major mechanism by which evolution occurs

Explanation:

The concept of evolution are both closely related in that natural selection is the major mechanism by which evolution occurs. This was proposed by Charles Darwin after his journey to the Galapagos Island on the HMS Beagle.

  • Evolution is the change in the characteristics of an organism over several generations.
  • Organisms evolved to in order to be at an advantage and naturally favored.
  • According to Charles Darwin, organisms evolved by the process of natural selection.
  • Natural selection is the process by which an organism becomes adapted to its environment.
  • Organisms with desirable trait are naturally favored with competitive and reproductive advantage in the environment.
