Place the ice cube under the wire gauze at the bottom of the test tube. Heat the mouth of the test tube now you can observe the ice cube melting slowly because the heat at the top of the test tube won't move to the bottom but moves higher.

What is the term for the answers provided by an experiment?

How many variables does a controlled experiment have?
An experiment of any kind can have infinitely many variables. A controlled experiment can have just as many, provided that all but one are kept exactly the same.
What was the Hershey Chase experiment and what were its key findings?
The Hershey-Chase experiment was a scientific study conducted in 1952 by Alfred Hershey and Martha Chase. They used bacteriophages, viruses that infect bacteria, to demonstrate that DNA, not protein, is the genetic material that carries hereditary information. The key finding of the experiment was that when the bacteriophages infected bacteria, only the DNA of the virus was injected into the bacterial cell, not the protein coat. This provided strong evidence that DNA is the molecule responsible for transmitting genetic information.
What did the Harlow monkey experiment demonstrate?
The Harlow monkey experiment, conducted by psychologist Harry Harlow in the 1950s, demonstrated the importance of comfort and emotional support in the development of attachment. Harlow used rhesus monkeys and provided them with two surrogate mothers: one made of wire that provided food and another covered in soft cloth that offered comfort. The monkeys overwhelmingly preferred the cloth mother, seeking her for comfort even when not feeding, highlighting the significance of nurturing and emotional bonds over mere physical sustenance in developing healthy relationships. This experiment profoundly influenced understanding of attachment theory and the emotional needs of infants.
Which scientist boiled broth in one beaker and left unboiled broth in another beaker and measured the growth of bacteria?
Louis Pasteur conducted the famous experiment with the boiled and unboiled broth to demonstrate that spontaneous generation of life does not occur. He showed that only the broth exposed to air developed bacteria, while the boiled broth remained sterile. This experiment provided evidence for the germ theory of disease and the importance of sterilization.
How much amylase enzyme should be used in the experiment?

Who provided evidence for the existence of a nucleus in an atom?
Ernest Rutherford
What did Ruthford's Gold Foil Experiment provide evidence for?
Rutherford's Gold Foil Experiment provided evidence for the existence of a small, positively charged nucleus at the center of the atom. This discovery led to the development of the nuclear model of the atom and overturned the previous plum pudding model.
How might a hypothesis for this experiment be stated?
"The hypothesis for this experiment is that increasing the amount of fertilizer provided to plants will lead to an increase in their growth rate compared to plants receiving standard or no fertilizer treatments."
Rutherford's gold foil experiment provided evidence for what statements?
There is a dense, positively charged mass in the center of an atom...
