What two ideas from geology were important to Darwin's thinking

Answers

Answer 1

Answer: the geologists that influenced Darwin's thinking with their work were Lyell and Hutton , together both are saying that the earth is millions of years old whereas people back then used to think that according to the bible earth was just about 6000 years old if you track the generations or the genealogies. of course not every single generation is noted on the bible. also the discovery of fossils suggests evolution,
in addition people used to think that earth hasn't changed neither its life since the moment of creation
in short, the ideas were that earth natural processes operate very slowly, thus the earth must be millions of years old. that made Darwin wonder "if the earth is very old and changing, would life change as well over time? also he realized that life evolvells with such a great amount of time

Sharks have highly developed _____.thermoreceptors
photoreceptors
olfactory receptors
mechanoreceptors

Answers

Among the options the best answer is "olfactory receptors" - as the sharks have a very good sense of smell. (they have the other receptors, but not as developed)
however, they are more famous for their electroreceptrors- they can sense the electric current around them!

Answer: olfactory receptors

Sharks have highly developed olfactory receptors. The olfactory receptors in animals allows them to sense the odor. Sharks have olfactory receptors more sensitive than humans. They have nostrils located on the underside of their snout, which they use for smelling not for breathing. The smell of the prey animal or the blood of any animal is detected by the shark with the help of these receptors.
