Answer:
They used radioactive labeling techniques to build two different types of phage.
Explanation:
In 1952, a set of experiments were carried out by American biochemists Alfred D. Hershey (1908-1997) and Martha Chase. They prepared two separate virus samples, one contained DNA labeled with a radioactive isotope and the other contained protein labeled with a different radioactive isotope. They grew the two types of viruses separately, infected bacteria with the two sets of phages and analyzed the bacteria for radioactivity. From the results obtained, Hershey and Chase concluded that the viral genetic material was DNA and not protein, reinforcing the observations previously made by Avery.
They do the same thing that all living and breathing things do! They breathe! When they breathe they are doing the same thing you are doing all day everyday. Inhaling oxygen and exhaling carbon dioxide.
Answer:
The correct answer is "temporal lobe".
Explanation:
The temporal lobe is the part of the brain involved in primary auditory perception by receiving sensory information from the ears and secondary areas and translating in into meaningful units such as speech and words. It was proved since 1954 by Mishkin and Pribram that the removal of the temporal lobe part of the brain produces a severe visual discrimination deficit in monkeys. This is the case for Maria's experiment, when the monkey was not able to differentiate between the rectangle and the cylinder anymore. Therefore, it is very likely that the part of the monkey's brain that was removed was the temporal lobe.
That is called uric acid and it helps them maintain internal homeostasis in hot climates by retaining water
Answer:
Insertion
Explanation:
An insertion is the addition of one or more nucleotide base pairs into a DNA sequence.
In this case, T was added to the strand
