Which condition is necessary for an experiment to yield useful data?
similar results should be obtained when the experiment is repeated .
What did Lazzaro Spallanzani contributes to microbiology?
He repeated John Needham's experiment in which nutrient fluids (Chicken broth) was put into a sealed flask then heated. The nutrient medium could be stored and microoganisms did not arise from it. This experiment disproved the Spontaneous Generation and paved the way for Pasteur's research. Spallanzani was largely criticised under claims that microorganisms needed oxygen to survive. He was also a pioneer in the fertilization an experiment which he produced with frogs. :) hope that helps.
What is it called when a segment of a chromosome is repeated?
The mutation in which a segment of a chromosome is repeated is known as duplication.
Why do scientists assume that experimental results can be reproduced?
Scientists assume that experimental results can be reproduced because they follow very specific steps when conducting experiments. These guidelines are known as the scientific method, and is designed so that experiments can be easily repeated and retested.
What takes advantage of repeated DNA sequences that do not code for proteins?
DNA fingerprinting is a technique that takes advantage of repeated DNA sequences that do not code for proteins. It is a useful technique in forensic science.
What increases the validity of an experiment?
Repeated trials of said experiment.
Why is repitition important in an experiment?
When conducting an experiment, repitition is often a good idea. This is because the data from different repeated trials could well very, meaning that the more repeated trials you have, the more accurate your final data is bound to be.
What should you do if repeated trials give very different results?
If , in the course of your experiment, you run repeated trials with differing results, it is necessary to ensure that only one variable is changing for each experiment. Recheck the data collected for errors.
What are trials in an experiment?
Trials are the amount of times a certain experiment is repeated.
What is the meaning of getting the same results on repeated trials?
If you repeat the experiment and you get different results, then the accuracy of your first trial is not correct.
What is the significance of a variable during an experiment?
a variable can throw the whole experiment off and will have to be repeated.
Why was Pangaeas hypothesis rejected?
because it obviously had no proof and the same results were not achieved when the experiment was repeated several times by different scientists.
Why was the Pangaea hypothesis rejected?

Which shows that the results of an experiment are reliable?
An experiment in which the results are repeatable....apex
Which experiment most likely has greater reliability?
D) Number 2 because the experiment was repeated and the results were always the same
l need the answers?
why should an experiment be repeated
How does a controlled experiment?
It works when repeated to get results that are the same
