The Griffith's experiment, the Avery-MacLeod-McCarty experiment, and the Hershey–Chase experiments were the set of experiments that established DNA as the key hereditary molecule. The Avery-MacLeod-McCarty experiment was an extension to the Griffith's experiment. The heat killed virulent S strain cells of the Griffith's experiment were lysed to form a supernatant containing a mix of RNA, DNA, proteins and lipids from the cell. The supernatent was equally divided into 3 parts after the removal of the lipids. The 3 parts were respectively treated with an RNAase to degrade the RNA, DNAase to degrade the DNA and proteinase to degrade the proteins. The treated supernatant was then added into the culture containing the non-virulent R cells. In case of the supernatant treated with the DNAse, no transformation of R cells into S cells occurred. The transformation of R cells to S cells occurred in the proteinase and the RNAse cases. This indicated that DNA was the hereditary molecule and not protein or RNA.
Answer:
I'm say yes
Explanation:
because we had animals to survive off of
an area or category or genre which is not liked or seen as useful to many.
living things need non living things to survive. Without food, water, and air, living things die. ... Plants use water from the soil, carbon dioxide from the air, and energy from sunlight to make their own food.
Scientists take more than one measurements because they want to make sure that their results are fairly accurate answer, result, or/ and explanation on a subject.
Reason: If a scientist just used one measurement or used even one testing group then in the near future, people might use that ONE measurement or testing group to prove questions. .
In actuality, using more than one measurements can help you go for a more precise answer. It is better to use more than one measurement or testing group that way you may have a more wide explanation of why something is that way.
For example, if a person wants to know why a softer ball(like a tennis ball) bounces higher than something like a box then the person will use more than one measurement. This will include the height of the bounce, the volume of the items used, the force of gravity on the object, and some other things.
(Hope this helps you better understand :) )
