extract the insulin from the bacterial culture

Because they speed up reactions that might otherwise take a really long time. Therefore experiments can be condensed into a reasonable time to do in class.

In recognition of her important discovery, Mitchell was presented with a gold medal by Frederick VI, king of Denmark, who had an amateur interest in astronomy himself. Consequently, Mitchell became the first professional female astronomer in the United States.

Genetics

Because technology might change in the future.

Carl Linnaeus (Carl von Linné) was a Swedish botanist who is credited for the modern biological naming scheme of binomial nomenclature. He is known as the father of modern taxonomy and one of the fathers of modern ecology.

A Dichotomous key is a method for identifying any unknown organism by asking a series of questions about the organisms characteristics

Yes Obviously

We generally credit Nikola Tesla, the Serbian-American inventor, with the pioneering work of identifying the rotating magnetic induction field idea and applying it to a device that generated torque - rotational energy or force. His work on this occurred in about 1882.

What do you call a person who studies floods

The first step in a scientific investigation is to ask a question. The second step is to gather information or conduct research. The third step is to make a hypothesis. The fourth step is to test the hypothesis. The fifth step is gather results and declare a conclusion.

An ethnomusicologist studies music in its cultural context. Ethnomusicologists focusing on primitive cultures study music-related artifacts to determine the role that music played in these societies.(APEX)

An anthropologist studies humans. They study culture, and biology as it relates to humans. They look back over history to study, as well as to study how humans currently live.

Wegener made a strong case for continental drift as you may know. E.g. similar rock strata on opposing continents, similar fossil types located in geographically distant regions, evidence of glaciation and the general jig-saw fit of the continents. He could not explain however how the continents moved, that is, what force was acting on them and causing them to drift. He suggested that a combination of centrifugal force from the Earth's rotation and gravitational forces from objects in space (similar to what causes tides) moved the continents. Calculations proved this to be impossible. Since he could not explain the mechanism because little about plate tectonics was known at the time, his ideas were not widely accepted in the scientific community.

Gravity is a term coined by Sir Isaac Newton.

Newton discovered Gravity. He noticed this phenomena in the world famous story when an Apple fell down from a tree under which Newton was sitting, and Newton thought, as to why the apple fall down and not upwards or sideways. Hence leading to his discovery of Gravity.

It is very, very, important to know about the soil as the food on which we are depending upon is grown on it and if we ourself don't know about the nature and properties of it then we would be unable to classify the sort of crop that could be grown on it

The beginning of 3rd century BC.

In Alexandria, Egypt, there are 2 surgeons named Herophilus and Erasistratus. Herophilus is also known as the Father of Anatomy. They together did the human cadaveric dissections for 30-40 years. After that, human dissection was prohibited for the next 1800 years.

Gregor Mendel was the first scientist to study inherited traits.

He invented the periodic table. You must know what that means; he was the father of basic chemistry.

Actually, he didn't discover the periodic table. He just arranged the only elements he had available in his day (not a lot) and arranged them based on patterns of # of protons, electrons, reactivity, etc. He didn't have an in-depth knowledge yet of electron configuration ;however, his "guess" turned out to have so many great implications that we now use his invention everyday everywhere.

There are quite a few ways for scientists to determine old weather patterns. Firstly, old records are quite useful. Meteorological devices have been around for a very long time, in fact, Galileo Galilei created a thermoscope in the late 1500's that would be similar to the modern thermometer.

Another way is to determine the Climates in the past. This can be done through cutting down trees and examining the rings in the trunk. A tree develops about a ring a year, and if the ring is thick, the year had lots of rainfall, if it's thin, then there wasn't much rain. Some trees date back thousands of years giving long and accurate reports.

Scientists can also determine climate from studying rock faces and observing the mineral deposits. As rock accumulates on the surface certain minerals appear and disappear at certain rates. This can show wind patterns, water patterns, and the patterns of foliage and fauna on the surface at the time of rock's formation.

Thirdly, Scientist can study global climate through cutting cross-sections of ice out of glaciers or the ice caps where ice has been accumulating for millenia. They can see how much of certain gasses, or seeds, were in the air at times, and determine how those would affect the global climate.

Fourthly, in the same way scientists cut the ice, they can also cut mud or silt straight out of the ground and examine it for certain pollen types, fossils, artefacts, or other clues about old weather in that area.

Hope this helped!

Archaeologists Archaeology:- 1. the scientific study of historic or prehistoric peoples and their cultures by analysis of their artifacts, inscriptions, monuments, and other such remains, esp. those that have been excavated. 2. Rare. ancient history; the study of antiquity.
