Suppose you have an X ray of an arm, which is taken because the doctor suspects a bone is broken. You also have a drawing showin
Vesnalui [34]

Answer:

An X-ray is done to diagnose the position of bones in the body whether its broken or not or in right place or not.

An X-ray machine is turned on to provide a visual of the bones showing bone condition. When the machine is turned on, X-ray travel through the body tissues, and due to the presence of calcium in bones, they absorb more X-rays, thus bones appear white against the black background of a radiograph.

These white bones on the radiograph will show the position of bones whether it's broken or not.

So, both the visuals that is X-ray and drawing showing visuals (the bones appear white) contribute valuable data to the given situation.

In 1665, a scientist named Robert Hooke examined a thin piece of cork through a microscope. The drawing below represents what he
-Dominant- [34]

The Englishman Robert Hooke (18th July 1635 - 3rd March 1703) was an architect, natural philosopher and brilliant scientist, best known for his law of elasticity (Hooke's law), his book Micrographia, published in 1665 and for first applying the word "cell" to describe the basic unit of life. It is also less well known that there is substantial evidence that Hooke developed the spring watch escapement, independently of and some fifteen years before Huygens, who is credited for this invention. Hooke also is recognised for his work on gravity, and his work as an architect and surveyor.


Hooke's Micrographia

Here, we focus on his pioneering work using the microscope to document observations of a variety of samples in his book Micrographia, published in September 1665.


Hooke began his famed career by initially studying at Wadham College, Oxford, where he worked closely under John Wilkins with other contemporaries, including Thomas Willis and Robert Boyle, for whom he built the vacuum pumps used in Boyle's gas law experiments. He also built some of the earliest telescopes, observing the rotations of Mars and Jupiter, and, based on his observations of fossils, was an early proponent of biological evolution. If that wasn't enough, he investigated the phenomenon of refraction, deducing the wave theory of light, and was the first to suggest that matter expands when heated and that air is made of small particles separated by relatively large distances, yet curiously Robert Hooke is somewhat overlooked in his contributions to science, perhaps as there were many people who wrote of Hooke as a difficult personality, being described as of "cynical temperament" and of "caustic tongue". There were also disputes with fellow scientists, including disputes with Isaac Newton over credit for work on gravitation and the planets. Though it must be remembered that Hooke lived at a time of immense scientific progress and discovery and none of the above diminish Hooke'

How can natural selection affect a predator-prey relationship?
wel
Predators and prey are both in a constant struggle for survival, foxes with bigger ears tend to catch more mice, and live longer, because of this, foxes with smaller ears don't live as long, pretty soon all foxes have larger ears. The same goes for prey, Mice with padded feet live longer due to the foxes having more trouble hearing them, pretty soon all mice have padded feet, and the cycle continues.
