Answer:
Oncogenes are mutated protooncogenes (see explanation below).
Explanation:
“Proto-oncogene” is the name given to various genes whose products stimulate cell proliferation. Examples may include growth factor receptors, and proteins involved in clearing cell cycle checkpoints. Mutations in a proto-oncogene may cause it to either become too rapidly transcribed and/or code for a product that functions in an unchecked manner. This may lead to unrestrained cell proliferation, a basic mechanism of cancer. When and if this mutation takes place, the proto-oncogene becomes known as an oncogene.
Oncogenes are altered versions of proto-oncogenes that can lead to uncontrolled cell growth, leading to cancer. They can produce too much or abnormal protein, upsetting the balance of cell division.
Oncogenes are genes which have the potential to cause cancer. In their normal state, they are referred to as proto-oncogenes, contributing to regular cell growth and division. However, when these genes are altered or mutated, they can become oncogenes that stimulate the cell cycle and lead to uncontrolled cell growth - a hallmark of cancer.
Typically, proto-oncogenes help regulate cell division and ensure that cells divide in a controlled way. However, various factors such as genetic mutations, can turn a proto-oncogene into an oncogene. These oncogenes can produce too much protein or abnormal protein, upsetting the regular balance of cell division and halting normal function. This often results in a cell growing and dividing too rapidly, which can lead to a cancerous tumor.

b: the vinegar solution was hypotonic , causing the egg to lose mass
c: the vinegar solution was hypertonic , causing the egg to gain mass
d: the vinegar solution was isotonic to the egg so the mass remained constant
a) is the right answer
Answer:
Process that involves rearrangement of the molecular or ionic structure of a substance, as distinct from a change in physical form or a nuclear reaction Hope this helps! Have a great day!
