Scientists

This is actually a little bit of both. Organisms that stayed somewhat the same needed to stay in similar climate situations. However, some organisms mutated or evolved to changing conditions, and were able to withstand various climates.

It is difficult to provide an exact number, but Alexander Fleming's discovery of penicillin, the first antibiotic, has saved countless lives by effectively treating bacterial infections. His work revolutionized medicine by introducing the era of antibiotics.

It may not be feasible for a single scientist to observe all stages of secondary succession in an abandoned field due to the long time span involved. Secondary succession can take decades to centuries to complete, with different stages requiring consistent monitoring over time. Additionally, the fieldwork required to observe these stages comprehensively may be too extensive for one scientist to manage alone.

Scientists studied seismic waves generated by earthquakes to understand the behavior of waves as they travel through different layers of Earth. By analyzing the speed, direction, and intensity of seismic waves, researchers were able to infer the composition and structure of Earth's interior, leading to the development of models like the Earth's layers (crust, mantle, core).

Nikola Tesla patented alternate current which is used worldwide to light house ad buildings. Edison began selling electricity with the direct current but lost all the grandeur.

Scientists ensure the accuracy of others' work by peer reviewing publications, replicating experiments, and sharing data for verification. They also attend conferences and collaborate with others in the field to discuss and validate findings. Additionally, scientists maintain transparency in their methodologies and results to allow for scrutiny and validation by others.

False. Classification is just one step in understanding an organism. Scientists continue to study and research classified organisms to learn more about their behavior, characteristics, and evolutionary history.

Trained scientists can engage in the study of parapsychology to explore unconventional phenomena within the framework of rigorous scientific methods. However, it is important to approach such studies with skepticism, adhere to established scientific principles, and remain open to the possibility of new discoveries.

About 90%. The reason that the number is so high is that while people were discovering things via some method that resembled the scientific method, "scientist" was not an occupation. Science was pretty much invented by Sir Isaac Newton and the number of scientists has exploded and increased exponentially since this time, hence the large percentage of scientists alive today.

For a full analysis of this question, including research on the number of PhD's granted in major countries since 1900, see Eric Gastfriend's work on the Future of Life Institute's blog. He concludes that around 80-90% is probably correct.

Scientists use evidence from comparative anatomy, fossil records, embryology, and molecular biology to create branching tree diagrams, also known as phylogenetic trees. These diagrams help to illustrate the evolutionary relationships between different species and how they have diverged from a common ancestor over time.

Scientists can learn about ancient civilizations, including their daily lives, health status, and burial practices, by studying mummies. They can analyze DNA to understand genetic relationships, study diet and diseases through bone and tissue analysis, and gain insight into ancient technologies such as embalming methods. Mummies provide a unique window into the past, offering valuable information about human history and evolution.

Clear communication is essential in science to avoid misunderstandings, ensure accurate dissemination of information, and facilitate collaboration among scientists. Clarity in communication helps to convey complex concepts in a way that is easily understood by a broader audience, including other scientists, policymakers, and the general public.

The flask that was not exposed to air/germs and remained sealed represents the control in Louis Pasteur's experiment. This flask helped to demonstrate that it was the air/germs that caused the spoilage and not just the broth itself.

False. Chemists study the science of substances.

Initially, evidence of matching coastlines and geological features across continents, as well as similarities in fossil records and rock formations, suggested a possible connection. Later, advancements in technology, such as sonar mapping of the ocean floor and the discovery of mid-ocean ridges, provided further support for the theory. The development of plate tectonics in the 1960s, which explained how continents move and interact with each other, ultimately solidified the acceptance of continental drift among the scientific community.

The average salary for medical scientists in the United States is around $88,790 per year. Salaries can vary depending on factors such as experience, location, and employer.

Alexander Fleming's goal was to find a cure for bacterial infections. He discovered penicillin in 1928, which revolutionized the field of medicine by introducing the first antibiotic to treat bacterial infections effectively. Fleming's work helped pave the way for the development of other antibiotics and significantly improved healthcare outcomes worldwide.

Scientists do research to expand our knowledge and understanding of the world around us. Research helps to answer questions, solve problems, and make discoveries that can lead to advancements in technology, medicine, and society as a whole. By conducting research, scientists are able to drive innovation and contribute to the collective body of knowledge.

Michael Servetus became a famous scientist through his works on medicine, theology, and geography. His most notable achievement was challenging the traditional understanding of the circulation of blood in the human body, which paved the way for modern concepts of pulmonary circulation. Despite his scientific contributions, Servetus faced persecution for his unorthodox beliefs and was eventually burned at the stake for heresy.

Gregor Mendel is the investigator whose studies formed the basis of modern genetics. He conducted extensive experiments with pea plants in the 19th century, identifying basic principles of heredity such as dominant and recessive traits, and laying the foundation for the field of genetics.

Robert Koch discovered the causative agents of several diseases including the bacteria responsible for anthrax (Bacillus anthracis), tuberculosis (Mycobacterium tuberculosis), and cholera (Vibrio cholerae). His work in identifying these microorganisms helped establish the field of medical microbiology.

We cannot directly observe what an atom looks like because they are too small. Instead, scientists use models and imaging techniques, such as electron microscopes and scanning tunneling microscopes, to infer the structure of atoms based on their interactions with other particles and their behavior in experiments. This has led to the development of atomic models that depict atoms as a nucleus made up of protons and neutrons surrounded by electrons in specific energy levels.

According to wikipedia, Hugh Fleming and Grace Stirling Morton.

Alfred Wegener, a German meteorologist and geophysicist, proposed the theory of continental drift in the early 20th century after observing cracks in the continents and similarities in rock formations and fossils across different continents.
