Scientists

Robert Hooke was the first scientist to observe cork cells in 1662 using a simple microscope he had built. He coined the term "cell" to describe the box-like structures he saw, reminiscent of small rooms monks lived in, known as cells.

Scientists can learn about Earth's mantle through seismic studies that analyze how seismic waves travel through the mantle, laboratory experiments that simulate mantle conditions, and by studying rare mantle-derived rocks that reach the Earth's surface through volcanic eruptions.

A scientist who studies weather and climate is called a meteorologist or a climatologist. Meteorologists focus on short-term weather patterns, while climatologists study long-term climate trends.

Kingdom Monera is divided into two groups, called Eubacteria and Archaebacteria. These two groups are both composed of tiny, ancient, single-celled organisms without organelles and generally with cell walls, but they differ greatly from each other in almost every other way. Scientists divided Archaebacteria and Eubacteria into these two groups mainly because of the environments they inhabit. Although Archaebacteriaâ??s name would suggest it is â??olderâ??, it is actually a younger group than Eubacteria, and very little is known about Archaebacteria because these species typically live in very hostile, extreme environments such as in acidic ocean thermal vents and miles below arctic ice sheets. Humans are much more familiar with Eubacteria, since we interact with these species every dayâ??most Eubacteria are completely harmless or beneficial, by way of fixing nitrogen for plant use in photosynthesis and other helpful functions. Archaebacteria differ from Eubacteria mainly in the chemical makeup of their cell walls, which scientists think hold the key to why Archaebacteria can live in such â??extremeâ?? conditions.

Sir Charles Lyell's work in geology, particularly his theory of uniformitarianism, helped scientists understand Earth's geological processes occurred slowly over time, shaping the Earth's surface. This concept laid the foundation for modern geological and evolutionary theories, guiding future scientific inquiries.

Scientists discovered Pangaea by studying the fit of the continents' coastlines, the distribution of fossils and rocks, and the matching geological features across continents. This evidence led to the theory of continental drift, proposed by Alfred Wegener in the early 20th century, which suggested that the continents were once part of a supercontinent called Pangaea.

The study of earth is geology, so a geologist.

atmospheric scientists

They may be but the more usual term for one studying the weather itself is "Meteorologist".

Nothing to do with meteors - astronomical objects - though.

Scientists now believe that plate tectonics, the movement of Earth's lithosphere plates over the semi-fluid asthenosphere below, is responsible for continental drift. This movement is driven by the convection currents in the mantle, leading to the gradual shifting of continents over millions of years. This theory has been supported by evidence such as the matching coastlines of continents, distribution of fossils, and rock formations.

Geography scientists are called geographers. They study the Earth's landscapes, environments, and the interaction between humans and their surroundings.

Charles Darwin. His theory is The Theory of Natarual Seletion. A theory that has been proved even today

A person who studies minerals is called a mineralogist. Mineralogists specialize in identifying, classifying, and studying the properties of minerals found in the Earth's crust. They often work in fields such as geology, mining, and materials science.

Alexander Fleming worked at St. Mary's Hospital in London, United Kingdom.

Scientists care about geography because it helps them understand the distribution of resources, species, and natural phenomena on Earth. By studying geography, scientists can explore the relationships between physical features and human activities, as well as how various factors like climate change and land use affect ecosystems and biodiversity. Geography provides a crucial framework for research in fields such as environmental science, climate studies, and urban planning.

A scientist who specializes in weather is called a meteorologist. They study atmospheric phenomena to understand and predict weather patterns.

A scientist might want to find out the cause of the sinkhole formation, how quickly it is enlarging, and if there are any potential risks to surrounding structures or groundwater. They may also investigate the geological conditions that contributed to the sinkhole formation.

Scientists study geological time by analyzing rock layers and fossils to determine the relative ages of different formations. They also use radiometric dating techniques to assign numerical ages to specific events or objects in Earth's history. By combining these methods, scientists can create a detailed timeline of Earth's geological past.

Louis Pasteur proved his germ theory of disease through a series of experiments that demonstrated the role of microorganisms in causing fermentation and disease. He conducted experiments with sterilized and unsterilized broths, showing that microorganisms were responsible for the spoilage of the unsterilized broth. Pasteur's work paved the way for the development of methods to control the spread of infectious diseases through sterilization and vaccination.

Geologists, mining engineers, environmental scientists, and metallurgists are the types of scientists commonly involved in mining activities in Australia. Geologists are responsible for identifying mineral deposits, mining engineers design and plan mining operations, environmental scientists ensure compliance with regulatory requirements, and metallurgists focus on extracting and processing minerals.

Scientists use enzymes known as restriction endonucleases to cut plasmid DNA at specific sequences. These enzymes recognize and cleave DNA at specific sites, allowing researchers to manipulate the plasmid for various genetic engineering applications.

When scientists find that their hypotheses are correct, they can develop theories or models to explain their findings. They then communicate their results through scientific publications, conferences, and presentations to share their insights with the scientific community. Additionally, they may design further experiments to test the validity of their theories and expand on their research.

This question would be too extensive to post here: Instead responding it, I recommend that you click on the link below ( Rocks and Minerals) . Thus, you'll learn everything about this subject. There are several methods of classifying, and it is not allowed to copy and paste answers here. However, to add a related link is allowed. Thank you.

the basic characteristics scientists look into to group organisms are:-

1) CELL STRUCTURE: whether it's prokaryotic(without a nuclear membrane) or eukaryotic(with a nucleur membrane). Also, whether it's unicellular or multicellular.

2)MODE OF NUTRITION: Whether it's autotrophic(prepares it's own food), heterotrophic(depends on others for food) or saprophytic(depends on dead matter)

3)COMPLEXITY OF ORGANISATION: Where the animal is placed in the evolutionary cycle. the higher on the evo. cycle, the more complex the organism...
