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.
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.
What apparatus used to observe reactions?
A common apparatus used to observe reactions is a laboratory beaker or test tube. These glassware allow for the observation of physical and chemical changes in substances during a reaction by noting changes in color, precipitation, gas evolution, or temperature. Other tools like spectrophotometers or microscopes may also be used to observe reactions at a more detailed level.
What type of reasoning may allow you to predict what you may expect to observe?
Inductive reasoning is often used to predict what you may expect to observe. This type of reasoning involves making generalizations based on specific observations or patterns. By using inductive reasoning, you can make educated guesses about future observations or outcomes based on past experiences.
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.
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.
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.
Allow children time to observe and listen?
well if there brats take all there fun away
Why do scientists use tools when they make observations?
Tools enable scientists to make more accurate observations, and to observe things that they otherwise could not observe. For example, microscopes allow scientists to observe bacteria, which otherwise are too small to see.
What can you observe through a microscope?
Through a microscope, you can observe tiny details that are not visible to the naked eye, such as cells, bacteria, and other microorganisms. Microscopes allow you to see these objects in greater detail and study their structure and behavior.
What is the law for running a stop sign in a neighborhood?
It's illegal. Stop at stop signs, observe, and if conditions allow, continue driving.
