How does urey's and miller's experiment support the theory that scientists think that the first life forms probably arose from nonliving materials?

Scientists don't "think" that the first life forms arose from non-living materials. However, they do accept abiogenesis as the only testable theory on the origins of life, as we know it.

The Miller-Urey experiment set out to prove that the chemical components of life can arise from natural processes. While it does not prove life can come from non-living matter, it does show that its' components can arise naturally.

How much do scientists spend on cloning each year?

It is difficult to estimate an exact amount, but funding for cloning research varies greatly across different scientific institutions and countries. The overall investment in cloning research is likely in the millions of dollars annually.

What scientist is known for working with pea plants?

Gregor Mendel is known for his work with pea plants and his discovery of the principles of heredity. He conducted experiments on pea plants in the mid-19th century which laid the foundation for the field of genetics.

Where do some scientists think these bacteria originated?

Some scientists believe that these bacteria originated in hydrothermal vents deep in the ocean, where conditions are extreme and unique. The high temperatures, pressure, and chemical composition of these environments are thought to have provided a suitable habitat for the evolution of such bacteria.

Who are sir Alexander flemings parents?

Sir Alexander Fleming's parents were Hugh Fleming, a farmer, and Grace Stirling Morton. Fleming was born in Lochfield, Scotland in 1881.

What evidence causes scientist to think that prokaryotes were the first organisms on the planet?

Scientists believe prokaryotes were the first organisms on the planet because they are simple in structure and lack a nucleus, making them more likely to have evolved early in Earth's history. Fossil evidence dating back over 3.5 billion years shows the presence of prokaryotic organisms, supporting the idea that they were among the earliest life forms. Additionally, prokaryotes are able to thrive in extreme conditions, similar to the conditions believed to have existed on early Earth.

Where do scientists obtain the majority of their modern knowledge about the history of life?

Scientists obtain the majority of their modern knowledge about the history of life from various disciplines, including paleontology, molecular biology, genetics, and comparative anatomy. By combining evidence from fossils, DNA analysis, and other methods, researchers can reconstruct the evolutionary history of different species and understand how life has evolved over time.

How did scientists determine Earth has layers?

Scientists determined that Earth has layers through various methods such as studying seismic waves from earthquakes, analyzing samples from drilling projects like the Deep Earth Sampling, and studying the behavior of materials under high pressure and temperature in laboratory experiments. These methods provide evidence for the composition and properties of Earth's layers, including the crust, mantle, outer core, and inner core.

Which scientist studies how to use plants for food medicine and other products?

A botanist or plant biologist studies how to use plants for food, medicine, and other products. They examine plant structure, function, evolution, and interactions with other organisms to understand their potential uses in various applications.

Why did mr Alexander Fleming become famous?

Sir Alexander Fleming became famous for discovering penicillin, the first antibiotic drug that revolutionized the treatment of bacterial infections. His accidental discovery in 1928 opened the door to a new era in medicine and earned him the Nobel Prize in Physiology or Medicine in 1945.

How much do environmental scientist get paid?

The salary for environmental scientists can vary based on experience, location, and employer. On average, Environmental Scientists in the United States make around $71,130 per year according to the Bureau of Labor Statistics. Entry-level positions may start at a lower salary, while those with more experience or advanced degrees can earn higher salaries.

What do scientists already know about the bottom of the ocean?

Scientists know that the bottom of the ocean is largely unexplored and covers over two-thirds of the Earth's surface. They have identified various deep-sea ecosystems, such as hydrothermal vents and cold seeps, that host unique life forms adapted to extreme conditions. Current research focuses on studying the geology, biology, and biodiversity of these deep-sea environments.

Who is Gregor Mendel and what did he discover about heredity?

Mendel did work with sweet peas. He learned that some traits are dominate and some are recessive. The trait for tall (T) peas are dominate while short (t) is recessive. He also worked with color, green (G) are dominate while yellow (g) are recessive. Besides working with just tall and short or green and yellow, he worked with them together. This last crossing with 4 traits produced 16 different combinations.

Why is it important for scientists to understand how viruses spread?

Understanding how viruses spread is crucial for scientists to develop effective strategies for disease prevention and control. By studying transmission routes, they can identify high-risk populations, implement targeted interventions, and limit the spread of infections within communities. This knowledge also enables scientists to develop vaccines and treatments to combat viral diseases effectively.

What is the word for scientist who studies plants?

A botanist is a scientist who studies plants, including their anatomy, physiology, ecology, and taxonomy.

Which scientist became famous for telling the world about the environmental harm caused by DDT?

Rachel Carson, an American marine biologist, is credited with bringing attention to the environmental harm caused by DDT in her book "Silent Spring" published in 1962. Her work raised awareness about the negative effects of pesticides on ecosystems and wildlife, sparking the modern environmental movement.

How do scientists find out about the earth's past climate?

most reliable is core samples In ice warmer weather gives deepersnow per seasonal cycle, think artic ice. tree ring dating , also core samples of ocean floor sediment ;man has keep records fr 3 to 5 thousand years mostly in languages nobody speaks ,but nature has always keepamazing records

Why do you think scientists recognize many more changes in the Phanerozoic eon than in the other eons?

Scientists recognize more changes in the Phanerozoic Eon because it encompasses a time period with an abundance of fossil records, allowing for detailed study and observation. In contrast, older eons like the Archean and Proterozoic have fewer preserved fossil records, making it harder to identify and document changes accurately. Additionally, the Phanerozoic Eon includes major events like the Cambrian Explosion and mass extinctions, which have left significant geological and biological evidence for researchers to analyze.

Why did scientists start studying viruses?

Scientists began to study viruses because they had found a factor that was smaller than bacteria but could still cause diseases. This factor came to be known as a virus. At that time, they didn't have the technology to see viruses. But they wanted to know if viruses were very small cells or simply non-living groups of molecules.

What did early scientists classify sponges as?

Early scientists classified sponges as plants because of their stationary nature and lack of obvious sensory organs. It was not until the 18th century that sponges were recognized as animals due to their ability to move, feed, and reproduce like other animals.

How do scientist define life?

Scientists define life as a characteristic that exhibits growth, reproduction, adaptation to the environment, response to stimuli, and maintenance of internal balance. These criteria differentiate living organisms from non-living matter.

Two scientists are given credit discovering the structure of dna.What is the name of those two sicentists?

The two scientists credited with the discovery of the structure of DNA are James Watson and Francis Crick. They proposed the double helix structure of DNA in 1953, based on data collected by Rosalind Franklin and Maurice Wilkins.

What did Giuseppe Piazzi use to discover Ceres?

Giuseppe Piazzi used a telescope to discover Ceres on January 1, 1801. He observed the celestial object while conducting a systematic sky survey, leading to the classification of Ceres as a new celestial body.

What sciences are considered biological?

Biology, zoology, botany, ecology, genetics, and microbiology are some examples of sciences that are considered biological. These fields study living organisms, their interactions with each other and their environment, and their fundamental biological processes.
