How can the measuring rate of photosynthesis be accurately determined in a controlled experiment?
The rate of photosynthesis can be accurately determined in a controlled experiment by measuring the amount of oxygen produced by the plant over a specific time period. This can be done using a device called a gas exchange analyzer, which can track the changes in oxygen levels in a closed system where only the plant is present. By monitoring the increase in oxygen concentration, scientists can calculate the rate of photosynthesis occurring in the plant.
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 does the Miller-Urey experiment work to simulate the conditions of early Earth and test the origin of life hypothesis?
The Miller-Urey experiment simulated the conditions of early Earth by creating a mixture of gases believed to be present in the atmosphere at that time, such as methane, ammonia, and water vapor. This mixture was then subjected to electrical sparks to mimic lightning, which was thought to have been a common occurrence on early Earth. The experiment resulted in the formation of organic molecules, including amino acids, which are the building blocks of life. This supported the hypothesis that the basic building blocks of life could have formed spontaneously on early Earth.
In Mendel's experiment why did traits show up in the f1 generation that were not present in the f1 generation?
the traits were recessive
Who were Stanley Miller and Harold Urey?
Stanley Miller and Harold Urey were two scientists who send electrical currents through gases that were believed to be Earth's early atmosphere (water vapor, ammonia, hydrogen, and methane). When the gases cooled, they thickened to make a salt water-like liquid that had things in it like amino acid, what is found in present-day cells.
Who was a famous American inventor that did a kite experiment and proved that electricity was present in lightning?
That would be Benjamin Franklin. Do not try that at home.
After an experiment what do the scientists do with the data?
After the experiment, scientists organize and analyze the data. Which therefore means that the scientists will create something to tell what is going on with there experiment and how long it goes for and if anything improved or something changed.
What is after the experiment scientists organize and the data?
After conducting experiments, scientists typically organize and analyze the data to identify patterns or trends. This analysis helps them draw conclusions, make inferences, and determine if the initial hypothesis was supported. Scientists may then present their findings through research papers, conferences, or scientific journals to communicate their results to the scientific community.
Assume that bacteria appeared on the meat in all three jars How would most scientists today explain this observation?
a.) Bacteria was present on the meat at the start of the experiment.
What is the role of IKI in the experiment?
to present the starch.
It is important to control variables in an experiment because?
in an experiment cantrolling variable is important as it helps to identify the limiting factors are present in the experiment, and also factor that do not necessarily affect the experiment.
What theory is there to show how life was formed which involves the interaction between hydrocarbons ammonia and lightning?
The Stanley-Muller experiment didn't prove that life formed from those elements, just some common and simpler amino acids, some of which are present in DNA.
What are the characteristicsof a good experiment?
There are many characteristics present during a good experiment. For example, if the experiment provides unbiased estimates for uncertainties and factor effects then the experiment should be considered good.
What are the Different ways to present experimental data?
different kind experiment data present bar graph
Is argon created by lightning?
No, argon is a noble gas that is naturally present in Earth's atmosphere and is not created by lightning. Lightning can generate ozone and nitrogen oxides in the atmosphere, but not argon.
Can you be struck by lightning even if you are not in rain?
Yes, lightning can strike even when it is not raining. In fact, lightning can travel long distances and strike outside of a rainy area. It is a common misconception that rain must be present for lightning to occur.
An experiment setup in which the independent variable is not present is called the?
When conducting experiments in science, it is important to have a baseline for knowing what happens if an independent variable is not present. In science, this is called the control experiment.
