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'

Answer:

Both cellular structures and cellular processes.

Explanation:

Magnifying lenses have been around since approximately 1000 AD. By 1590, the first simple microscope was created. Less than 100 years later, Robert Hooke used this new technology to suggest that substances are composed of cells. His drawings show how microscopes can be used to examine cell structure.

Microscopes continued to develop over time. In 1931, the electron microscope was invented, so cellular organelles could be viewed in greater detail. Now, as demonstrated by the second image, it is possible to not only see cellular structures, but also cellular processes, such as mitosis.

One hypothesis that explains the result is : A) Two genes are involved with  12:3:1  epistasis, such that A_B_ and A_bb are black, aaB_ is brown,and aabb is green.

Explanation:

  • This is a case of Dominant Epistasis.
  • When two genes are involved and presence of dominant allele of one gene masks the effect of either allele of the second gene then the epistasis is termed as dominant epistasis.
  • In the given case black :brown: green ratio is approximately equal to  12:3:1.
  • Here presence of a dominant A allele that is responsible for the black colour masks the effect of either allele of B. Therefore A_B_ and A_bb produces black beetles
  • Again , absence of dominant A allows B to express itself and Brown beetles are produced thus aaB_ is brown.
  • When both the genes are present as recessive alleles, neither brown nor black colour is expressed and the beetles are green.Thus, aabb are green.
