A piece of chromosome 9 and a piece of chromosome 22 break off and trade places.

Explanation:

The BCR-ABL gene is formed on chromosome 22 where the piece of chromosome 9 attaches. The changed chromosome 22 is called the Philadelphia chromosome.

Answer:

"Philadelphia chromosome. A piece of chromosome 9 and a piece of chromosome 22 break off and trade places. The BCR-ABL gene is formed on chromosome 22 where the piece of chromosome 9 attaches. The changed chromosome 22 is called the Philadelphia chromosome."

"The Philadelphia chromosome forms when chromosome 9 and chromosome 22 break and exchange portions. This creates an abnormally small chromosome 22 and a new combination of instructions for your cells that can lead to the development of chronic myelogenous leukemia."

"People aren't born with a Philadelphia chromosome. It happens because of a mistake our bodies can make later in life. The mistake is that a piece of chromosome 9 sticks to a piece of chromosome 22. This mistake leads to a very serious blood cancer called "chronic myeloid leukemia," or CML."

"The Philadelphia chromosome is seen in more than 90% of patients with CML but also in 5% or less of children with ALL (20% of adult ALL) and in 2% or less of children with AML. Different isoforms of the fusion gene may be present in ALL. ALL in a child with the Philadelphia chromosome has a much poorer prognosis."

"Currently, the standard of care in the frontline setting for fit patients is TKI in combination with chemotherapy. Age-adjusted chemotherapy or corticosteroids alone have been used with TKIs in elderly patients with comorbidities with modest long-term benefit."

Phenylalanine hydroxylase (PHA) performs an enzymatic function during the conversion of phenylalanine, to tyrosine. Existing naturally in several types of foods, for instance, breast milk, PKU is an essential α-amino acid and one of the plethora of amino acids used in the formation of proteins. Phenylalanine exists in three forms; L-phenylalanine, D-phenylalanine (mirror image of L-phenylalanine), and DL-phenylalanine which is a typic combination of D and L-phenylalanine, and unlike D and L- phenylalanine, is not found in foods. On the other hand, tyrosine, apart from being a derivative of phenylalanine, is a non-essential amino acid that forms part of the list of amino acids utile during the constitution of proteins. Ordinarily, lack of PAH leads to the accumulation of phenylalanine (the phenylalanine is not converted to tyrosine) leading to the development of a disease called Phenylketonuria (PKU).

Section C highlights metalloids in the periodic table. Therefore, option C is correct.

Metalloids, also known as semi-metals, are a group of elements that have properties that are intermediate between those of metals and nonmetals. The metalloids are located on the periodic table along a diagonal line between the metals and nonmetals and include the elements boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and polonium (Po).

Metalloids have a combination of metallic and nonmetallic properties and can exhibit characteristics of both depending on the conditions. Metalloids are also important in biological systems, where they play essential roles in processes such as protein folding and enzyme activity.

Thus, section C highlights metalloids in the periodic table. Therefore, option C is correct.

Given what we know, we can confirm that the significant increase in oxygen in the Earth's atmosphere 2 to 2.5 billion years ago is due to cyanobacteria.

These are tiny bacterial organisms. They were amongst the first organisms to use photosynthesis to sustain life. The sudden boom of cyanobacteria accounts for the rapid increase in oxygen given that they will use carbon dioxide to produce sugar through photosynthesis, expelling oxygen in the process.

Therefore, we can confirm that the significant increase in oxygen in the Earth's atmosphere 2 to 2.5 billion years ago is due to cyanobacteria.
