Scientists

A scientist looks for various physical and chemical properties in soil, such as texture, pH level, nutrient content, organic matter content, and presence of contaminants. These factors can provide insights into soil quality, fertility, and overall health, which is crucial for agriculture, ecology, and environmental monitoring.

Scottish geologist James Hutton proposed the theory of uniformitarianism in the late 18th century, stating that the processes shaping the Earth have been occurring over long periods of time. This concept challenged the prevailing view of a young Earth and laid the foundation for modern geological principles and dating methods.

James Watson and Francis Crick are the two scientists credited with developing the structure of the double helix of DNA in 1953.

Yes, the genetic scientist, Francis Collins is still alive.

In 2013 he is 63 years old and currently lives in Staunton, Virginia, USA.

He qualified with distinction in 1906 and began research at St. Mary's under Sir Almroth Wright, a pioneer in vaccine therapy. He gained M.B., B.S., (London), with Gold Medal in 1908, and became a lecturer at St. Mary's until 1914. He served throughout World War I as a captain in the Army Medical Corps.

He was elected Professor of the School in 1928 and Emeritus Professor of Bacteriology, University of London in 1948.

Early in his medical life, Fleming became interested in the natural bacterial action of the blood and in antiseptics. He was able to continue his studies throughout his military career and on demobilization he settled to work on antibacterial substances which would not be toxic to animal tissues. In 1921, he discovered in «tissues and secretions» an important bacteriolytic substance which he named Lysozyme. About this time, he devised sensitivity titration methods and assays in human blood and other body fluids, which he subsequently used for the titration of penicillin. In 1928, while working on influenza virus, he observed that mould had developed accidently on a staphylococcus culture plate and that the mould had created a bacteria-free circle around itself. He was inspired to further experiment and he found that a mould culture prevented growth of staphylococci, even when diluted 800 times. He named the active substance penicillin.

A scientist that studies plants is known as a botanist.

Scientists used a variety of dating techniques including radiometric dating of rocks, study of fossil records, and analysis of the Earth's magnetic field to infer Earth's age. By studying the decay rates of radioactive isotopes in rocks and minerals, they were able to estimate that the Earth is approximately 4.54 billion years old.

Environmental scientists or environmental researchers typically study ways to protect the environment through research and analysis of various ecosystems and human impacts on the environment.

Robert Hooke received recognition for his pioneering work in biology and physics, particularly for his contributions to cell biology and his development of Hooke's Law in physics. He is best known for coining the term "cell" and for his observations using a microscope, which laid the foundation for the field of microbiology.

Isaac Newton was a physicist and mathematician known for his laws of motion and universal gravitation. He also developed calculus independently, furthering the field of mathematics. His work on optics led to the understanding of the nature of light and how it interacts with matter.

you call a scientist a scientist but there are different study's in science which are called different names i hope this helps.:)

Scientists study the mantle indirectly by analyzing seismic waves from earthquakes, studying volcanic eruptions, and examining rock samples brought to the surface by volcanic activity. By combining these methods, scientists can gain valuable insights into the composition, temperature, and behavior of the Earth's mantle.

• to helpso that every scientist in every nation uses the same universal name
• helps avoid confusion and duplication of the name

The four methods that scientists use to study homologies include using HSPs in Viterbi algorithm, bi-directional Viterbi algorithm, biased hidden Markov models and using HSPs to position target regions. They also use Data sets which include Training data set of human genes and Validation and testing data sets of homologous genes.

I'm not entirely sure about fungi, but I think so. The type of fungi on the body should help the scientists to identify how long they have died and where they died...I do know for sure that a type of flesh eating bugs do help the forensic scientists in their studies sometimes. They use the maggots to clean off the flesh from then bones so they can study the bones instead.

Jean-Baptiste Lamarck proposed the theory of evolution known as Lamarckism, which suggested that organisms evolve toward perfection and complexity through the inheritance of acquired traits. This theory has been largely discredited in favor of Charles Darwin's theory of natural selection.

Hibiscus flowers are primarily insect-pollinated, relying on bees, butterflies, and other insects to transfer pollen between flowers for successful pollination. This is due to the structure of the flower, which is designed to attract and accommodate specific pollinators.

Scientists study the Earth's interior to better understand its composition, structure, and behavior. This knowledge helps in understanding geological processes such as earthquakes and volcanic eruptions, as well as the evolution of our planet over time.

Deep canyons are formed when rivers erode many layers of rock. The pattern of rocky layers, as well as the layers themselves, have a lot of information for geologists about how the layers were formed, atmospheric conditions, disruptions, volcanic eruptions, major fires and so on. It would be difficult or impossible to expose so much of this over such a great distance.

Alexander Fleming discovered penicillin, the first effective antibiotic, in 1928. This groundbreaking discovery revolutionized medicine by providing a treatment for bacterial infections that had previously been difficult to manage. Fleming was awarded the Nobel Prize in 1945 for his work on penicillin.

Scientists age rocks using various methods, such as radiometric dating which measures the decay of radioactive isotopes within the rock, or by studying the layers of rock and fossils found within to determine its relative age based on the principle of superposition. These methods help scientists determine the age of the rock and gain insight into Earth's history and past geological events.

Yes Galileo was very important, because if he wasn't born than we might not even now about the stars, the planets, the moon, or even about the universe.

And why is that? That is because Galileo was the one whom discovered it.

Galileo was also the one whom "invented" science, math, and other great things we now do in school today.

Galileo was the one whom invented the telescope, the thermometer, and other great and useful things that we use in our every day lives.

A soil scientist is someone who studies and knows about the properties of the types of soil on the earth's surface. Of what they are composed, how they behave under various types of mechanical or chemical stress, their value to agriculture, how they may be improved, how they are distributed around the globe and so on.

Scientists explain the arrangement of continents today through the theory of plate tectonics. This theory states that the Earth's lithosphere is divided into several large plates that float on the semi-fluid asthenosphere beneath. Movements of these plates through processes like seafloor spreading, subduction, and continental drift have shaped the current arrangement of continents.

Scientists use fossil evidence to prove the existence of organisms that lived in the past, how life has evolved over time, the environmental conditions of ancient ecosystems, and the relationships between different species. Fossils provide valuable information about the history of life on Earth and help scientists reconstruct evolutionary pathways.
