Answer:
The three experiments are:
Griffith performed an experiment by which he observed that harmless R strain of the bacteria transformed into harmful S strain when mixed with heat-killed S strain.
He concluded that the "transforming principle" from the heat-killed S strain bacteria transformed the R strain.
- Avery, McCarty, and MacLeod- Identification of transforming principle
They identified that the nature of the transforming principle mentioned by Griffith.
They used digestive enzymes such as proteases, RNase, and DNase.
They conclude that the transforming principle was DNA in nature.
- The Hershey-Chase experiment
They used radioactive sulfur to label proteins and radioactive phosphorus to label DNA in the bacteriophage.
The infected bacteria were blended and centrifuged.
The radioactive phosphorus, that is, DNA was found inside the cell whereas the radioactive sulfur, that is, proteins were found outside the cell.
It also proved that the genetic material was DNA, not protein or RNA.
You would find:
Near the plasma membrane of the leading edge of the cell, and near the plasma membrane of the trailing end of the cell.
Hope this helps.
Given the symptoms shown by Marcos, we can infer that the organelle that may be causing his problems is the mitochondria.
The mitochondria are one of the most famous and important organelle within a cell. Found in most eukaryotic cells, they are the organelle responsible for most of the energy production of a cell, and throughout the cells of the body, they become responsible for the energy production of the organism. This is the origin of its famous <em>"</em><u><em>Powerhouse of the cell</em></u><em>"</em> title. Mitochondria produce energy in the form of ATP.
ATP is a molecular compound necessary for most of the reactions that take place in a cell. It is so common as a requirement for any cellular activity that ATP is known as the "molecular currency". Marcos is said to be experiencing chronic fatigue, which is a symptom of mitochondrial disease. When the mitochondria of an organism's cells are not functioning as they should be, the cells do not have the energy needed to perform basic functions.
In reaction to this, the body sends signals to the brain to go to sleep, which minimizes energy consumption by slowing down the metabolic processes which require ATP and thus gives the body time to produce more energy. For these reasons, we can conclude that the fatigue and problems Marcos is experiencing are due to mitochondrial disease.

<h2>Answer:</h2>
a. one allele from each parent
<h2>Explanation:</h2>
An allele in biological sciences is one of the possible forms of a gene that it can inherit. Most genes have two alleles, a dominant allele and a recessive allele. When Gregor Mendel crossed a tall plant with a short plant, the F1 plants inherited an allele for tallness from the tall parent and an allele for shortness from the short parent.
Answer:
range from wings in flying animals like bats, birds, and insects, to fins in animals like penguins and fish, plants and other organisms can also demonstrate analogous structures such as sweet potatoes, which have the same function of food storage
