It allowed him to see the pathway of protein secretion from the rough ER to the golgi apparatus via vesicles to the nuclear membrane via vesicles, and then out of the cell. He was able to see it by staining radioactive proteins and looking at them at different times after the injection of the radioactive amino acid occured to see where the proteins were.
What else can I help you with?
If systems experiments and models are types of scientific tools. explain why each of these things can be considered a scientific tool?
Systems experiments are scientific tools because they allow researchers to manipulate variables and observe how different components interact within a system. Models are scientific tools because they help scientists simulate complex systems and make predictions about how they will behave under different conditions. Both tools enable scientists to study complex phenomena and generate testable hypotheses.
Scientists can test predictions for situationsin which impossible or unethical to use experiments?
Scientists can use computer simulations, mathematical models, and observational studies to test predictions for situations where experiments are impossible or unethical. These methods allow researchers to make predictions based on existing data, theories, and principles without conducting actual experiments.
What tool would allow you to observe that salt crystal are box shaped?
A microscope, specifically a polarizing light microscope, would allow you to observe that salt crystals are box-shaped. Under magnification, the distinct cubic structure of sodium chloride (table salt) becomes visible, showcasing its characteristic geometric form. Additionally, using a stereo microscope can also provide a clearer view of the crystal morphology.
What did Galileo not observe through his telescope?
Galileo did not observe the rings of Saturn as clear, distinct rings; he initially thought they were "ears" or moons beside the planet due to the limitations of his telescope. He also did not observe the full spectrum of colors in a rainbow, as the technology of his time did not allow for detailed studies of light dispersion. Additionally, he could not detect the presence of planets beyond Saturn, such as Uranus and Neptune, which were discovered much later.
Why are coloured liquids good for diffusion experiments?
Colored liquids are good for diffusion experiments because they allow you to visualize and track the movement of particles as they spread out. The color helps to easily see the change in concentration over time, making it easier to measure and analyze the rate of diffusion.
How is a controlled experiment different from an observational study?
In a controlled experiment, researchers manipulate variables to observe their effect on outcomes, while in an observational study, researchers observe natural variations in variables without manipulating them. Controlled experiments allow for stronger causal inferences compared to observational studies because they can establish cause-and-effect relationships.
Do periscopes allow you to see hidden objects?
No, periscopes allow you to observe objects while you are hidden.
How are experiments used in the experimental design process?
Experiments are a fundamental component of the experimental design process as they allow researchers to systematically manipulate variables and observe the effects of those manipulations on dependent variables. This process enables the establishment of cause-and-effect relationships, providing insights into the underlying mechanisms of phenomena. By carefully controlling conditions and randomizing subjects, experiments reduce bias and improve the reliability of results. Ultimately, the findings from experiments inform conclusions and guide further research or practical applications.
What does satellite images allow scientists to observe?
Whatever they are focussed on.
Would the little albert research study be conducted today?
no because of the board of ethics in the US today does not allow for these kind of experiments to be performed. European countries on the other hand may allow for such experiments.
What scientific tool do you use to observe organelles?
Either a light microscope or an electron microscope can allow you to observe cell organelles.
Can you sit in on college classes to observe and learn"?
Yes, some colleges allow visitors to sit in on classes to observe and learn, but it is important to check with the specific college or professor beforehand to see if they allow this and what their policies are.
What are advantages of field experiments?
Field experiments offer several advantages, including high ecological validity, as they take place in natural settings where participants behave more authentically. They also allow researchers to observe real-world outcomes and interactions, enhancing the relevance of findings to everyday situations. Additionally, field experiments can help identify causal relationships more effectively than observational studies, as they often involve manipulation of variables in a controlled yet realistic environment.
Why are experiments important in science and how do they contribute to our understanding of the natural world?
Experiments are important in science because they allow researchers to test hypotheses and gather empirical evidence to support or refute their ideas. By conducting experiments, scientists can observe how variables interact and cause specific outcomes, leading to a deeper understanding of natural phenomena. This empirical evidence helps to build a body of knowledge that contributes to our understanding of the natural world and allows us to make informed decisions based on evidence rather than speculation.
What are some advantages from human experiments?
Human experiments, often conducted in clinical trials, provide critical insights into the efficacy and safety of new treatments, medications, or interventions. They allow researchers to observe complex biological responses in real-time and gather data that can lead to improved healthcare outcomes. Additionally, human studies can help identify potential side effects and optimize treatment protocols tailored to diverse populations. Overall, these experiments are essential for advancing medical knowledge and developing effective therapies.
How so experiments help scientists leanr about the world?
Experiments allow scientists to test hypotheses and observe the effects of variables in controlled conditions, which provides empirical evidence to support or refute their theories. By systematically manipulating factors and measuring outcomes, researchers can uncover causal relationships and deepen their understanding of complex phenomena. Additionally, experiments can lead to new discoveries and innovations by revealing unexpected results that prompt further investigation. Overall, this methodical approach is crucial for advancing knowledge in various scientific fields.
Allow children time to observe and listen?
well if there brats take all there fun away
