Who First to record a microscope biological observation?
Antonie van Leeuwenhoek, a Dutch scientist, was the first to record biological observations using a microscope. He used single-lens microscopes of his own design to study microorganisms in the 17th century.
Where do scientist look for evidence of evolution?
Scientists look for evidence of evolution in the fossil record, by studying similarities in DNA sequences among different species, by observing adaptations in living organisms, and by studying natural selection and genetic drift.
How do scientists know living things are related?
Scientists use various methods to determine if living things are related, such as comparing similarities in DNA sequences, anatomical structures, and embryonic development. These similarities suggest a common ancestry and evolutionary relationship between organisms. Additionally, the fossil record and biogeographical distribution of species also provide evidence for relatedness among living organisms.
Why do most scientist believe that all life on earth evolved from a single-felled ancestor?
Scientists believe in the theory of universal common descent because it provides a coherent explanation for the diversity of life on Earth. Evidence from various fields such as genetics, biochemistry, and the fossil record supports the idea that all living organisms share a common ancestor. Additionally, the theory has successfully predicted and explained many observations in the biological world.
Why do scientist believe that all life on earth evolved from a singe celled ancestor?
Scientists believe that all life on Earth evolved from a single-celled ancestor because of the similarities found in the genetic code and cellular structure of all living organisms. This suggests a common origin and shared ancestry. Additionally, the gradual changes observed in the fossil record and the patterns of biodiversity support the idea of evolution from a common ancestor.

How would a scientist record a birdsong?
Using a recorder :P
Who was the first person to discover bacteria in saliva?
Leeuwenhoek's wrote a letter about how he scraped plaque off of his teeth and put it under a microscope. This letter was the first record of bacteria seen living inside of the human body.

What are the preserved remains of living organisms arranged by age?
Fossils are the preserved remains of living organisms arranged by age in the Earth's layers. They provide evidence of past life forms and help scientists understand the history of life on Earth through the process of fossilization. By studying fossils, researchers can reconstruct the evolutionary relationships and environmental conditions of ancient organisms.
What equipnet do scientist use for earthquakes?
A Seismograph to record the magnitude of the earthquake.
What do scientist use often to study macro evolution?
The fossil record
What do scientist compare dinosaur fossil to when they classify them?
Other fossils already placed in the fossil record, and similar animals living today. The key to the past is in the present, as my geology professor would say.
What should a scientist do after he or she experiments?
Record the data and form a conclusion based on the results.
How do scientist record seismic waves?
Scientists use an insrument with the name of a seismograph
