Is a way of organizing data that is used to show changes that occur in related variables?
A line graph is useful for showing changes that occur in related variables.
What happens when the data in an investigation does not support the original hypothesis?
Answer Expert Verified What happens when the data in an investigation does not support the original hypothesis is that the hypothesis is revised. Hypothesis-this is a an idea or an explanation for something that is based on known facts but has not yet been proved.
What should you do when your data does not support your hypothesis?
Formulating a New Hypothesis If the initial hypothesis is not supported, you can go back to the drawing board and hypothesize a new answer to the question and a new way to test it. If your hypothesis is supported, you might think of ways to refine your hypothesis and test those.
Does the data support the hypothesis?
A hypothesis is a proposed idea that may explain an observation or phenomena. It is verified by testing it. If the data supports the hypothesis, then we consider the hypothesis to be verified and true.
How do you support a hypothesis?
Hypothesis basics The basic idea of a hypothesis is that there is no pre-determined outcome. For a hypothesis to be termed a scientific hypothesis, it has to be something that can be supported or refuted through carefully crafted experimentation or observation.
Did the data support Martha hypothesis?
The data supported Martha’s hypothesis because it supports that predators go toward the frass exclusively. Since they go toward the frass, caterpillars must shoot the poop to be undetected. Data collected should be observatory to see the reasons why they do.
Why did Hershey and Chase use bacteriophages?
Alfred Hershey and Martha Chase used the bacteriophages because of their connection to DNA. In one batch, the phages (short for bacteriophages) were grown with radioactive phosphorous, which means it was incorporated into phage DNA. The radioactivity in the pellet was measured and it was also measured in the liquid.
Why did Hershey and Chase use a blender?
After introducing to the phage culture to the bacterial sample, they used a Waring blender to violently disturb the infected bacteria, causing the protein shells to detach from their hosts.
What does it mean when your hypothesis refuted?
A hypothesis or model is called falsifiable if it is possible to conceive of an experimental observation that disproves the idea in question. That is, one of the possible outcomes of the designed experiment must be an answer, that if obtained, would disprove the hypothesis.
Why must a hypothesis be falsifiable?
Falsifiability is the capacity for some proposition, statement, theory or hypothesis to be proven wrong. That capacity is an essential component of the scientific method and hypothesis testing. The requirement of falsifiability means that conclusions cannot be drawn from simple observation of a particular phenomenon.
What did the Hershey-Chase experiment prove?
The Hershey-Chase experiment, which demonstrated that the genetic material of phage is DNA, not protein. The experiment uses two sets of T2 bacteriophages. In one set, the protein coat is labeled with radioactive sulfur (35S), not found in DNA.
Why was the Hershey-Chase experiment successful?
Key to the success of the experiment was showing that viral infection was unaffected by violent agitation in a kitchen blender (a Waring Blendor) which removed the empty viral protein shells from the bacterial surface. The Hershey-Chase experiment became known as the “blender experiment.”
How did Hershey and Chase use radioactivity to draw a conclusion about proteins and DNA?
Hershey and Chase studied bacteriophages which are viruses that attack bacteria. They labeled the bacteriophage with radioactive isotopes to see where it goes when a virus attacks. They discovered that nearly all the radioactivity was found in phosphorus, confirming that DNA contains genetic material, not protein.
What was the overall conclusion of the Hershey-Chase experiment?
Hershey and Chase concluded that DNA, not protein, was the genetic material. They determined that a protective protein coat was formed around the bacteriophage, but that the internal DNA is what conferred its ability to produce progeny inside a bacterium.
What are the 3 key roles of DNA?
What are the three key roles of DNA? DNA must store, copy, and transmit information. Why would the storage of genetic information in genes help explain why chromosomes are separated so carefully during mitosis? Storing information is important because the loss of DNA will lead to a loss of genetic information.
What was the conclusion to the Hershey and Chase experiment?
Hershey and Chase concluded that protein was not genetic material, and that DNA was genetic material. Unlike Avery’s experiments on bacterial transformations, the Hershey-Chase experiments were more widely and immediately accepted among scientists.
What was the conclusion of the Hershey chase experiments quizlet?
What was the conclusion of the Hershey-Chase experiment? DNA, not protein, enters bacterial cells and directs the assembly of new viruses.
What did Avery conclude caused transformation?
What did Avery conclude caused transformation? DNA was the transforming factor. The harmless bacteria would not have been transformed, and the mice would have lived.
Which is incorrect about Hershey and Chase experiment?
Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. ∗ Viruses grown in the presence of radioactive phosphorus contained radiactive DNA but not radioactive protein because DNA contains phosphorus but protein does not.
Which of the following is the most important reason Hershey and Chase chose to use bacteriophages in their experiments?
Bacteriophages were used because they contain little more than DNA and protein. Alfred Hershey and Martha Chase used the bacteriophages because of their connection to DNA. In one batch, the phages (short for bacteriophages) were grown with radioactive phosphorous, which means it was incorporated into phage DNA.
Which of the following statements about Hershey and Chase experiment are correct?
The correct option is (E) Hershey and Chase experiment lent strong credence to the idea that DNA is the hereditary material, at least of viruses. The Hershey-Chase blender experiment proved that phage DNA is the genetic material in bacteriophages or viruses, not protein.
What combination of radiolabeling is correct in case of Hershey and chases demonstration of DNA as genetic material in T2 bacteriophage?
What combination of radiolabelling is correct in case of Hershey and Chase’s demonstration of DNA as genetic material in T2 bacteriophage? Explanation: The two factors considered by Hershey and Chase were the simple composition of T2 bacteriophage, that is, DNA and protein.
