Because they were the early studies of genetics.
Ecologists are typically least likely to collect data by doing controlled experiments, as their studies often involve observing and analyzing natural systems in their environment. Ecologists focus on how organisms interact with each other and their surroundings, so their research often involves field observations rather than controlled experiments in a lab setting.
A botanist studies plants, including their classification, behavior, ecology, and evolution. They may work in various settings such as laboratories, greenhouses, or field research sites to conduct experiments, collect samples, and analyze data to contribute to our understanding of plant life.
the reason they are so reliable is because he used peas as his plant of interest. an peas have only 2 different things they can be. short or tall. so it was easy to conclude all of the different outcomes of the offspring of the pea plants because of the of his drawn punnett square. which shows that if a tall dominant pea plant goes with a short it will be tall. and if it goes with a tall it will be tall. but if short goes with short then it will be short. so only 25% vof the time a pea plant will be short
Watson and Crick did not conduct experiments of their own to discover the structure of DNA. Instead, they used existing data, particularly Franklin's X-ray diffraction images, to propose the double helix model of DNA in 1953. Their model was based on analyzing and interpreting the data with the help of Chargaff's rules.
Laboratory tools improve the observations made by a scientist by providing precise measurements, enhancing accuracy and reproducibility of experiments, and enabling the scientist to analyze samples at a microscopic level. Additionally, these tools can allow researchers to perform experiments that would not be possible otherwise, ultimately leading to a deeper understanding of the phenomena under investigation.
It's important to repeat experiments so then you know that you did the experiment right.
The main possible advantage is that in an experiment, it is possible to control some of the variables so that it is easier to measure the effect of key variables. In observational studies, no such control is possible.
because the thing that she studies are so important she studies fish
Scientists publish the details of important experiments so that people can recreate it and see the results for themselves.
It's important so that they can perform experiments and gather data.
Life is important so as studies but if no life cannot study. Prefer life is more important. Ebenezer : Well, Life IS important but in order to sustain your life you must have Knowledge to Survive. Studies might be the answer.
so scientists can compare result
Social Studies and Math are very important subjects so it will be bad if you fail them.
so it can be a fair test
The can, but not always. Scientists often collaborate with others during their experiments and studies, and so an ornithologist might work with a partner, and also have to work alone.
It is important to plan experiments because if you don't know what you are going to do, and you get something wrong, then you wont know how to correct the procedure so it will work. If you plan an experiment, then you can always go back and read it.
To prevent bias; neither the doctor or patient know who gets the drug so there is no way for subjective bias to be applied to either.
