A theory that states that only the organism with traits that are useful to the environment survive. For example, short-neck giraffes would’ve died out years ago as they can’t reach the trees nor eat grass on the ground.
Examining tumor tissue for driver mutations can help plan treatments that stop cancer cells from growing.
tumors was EGFR, followed by TP53 (18%), SETD2 (11%) and SMARCA4 (11%). More than 72% (81/112) of cases have mutations in at least one driver gene.
For example, the TP53 tumor suppressor gene is a driver gene, but it is only functional when both alleles of her TP53 gene are mutated. Furthermore, mutations can act as drivers only at certain stages of cancer.

Yes our lungs will be clean and perfect.
Answer:
The correct answer would be C. ³⁵S has more neutrons than ³²S; Hershey and Chase used it because it is radioactive and can be easily traced.
Sulfur-35 (³⁵S) is one of the isotopes of the sulfur which has 16 protons (same as sulfur-32) but 19 neutrons as compared to the 16 neutrons of sulfur-32.
It is a radioactive isotope which breaks down by beta-decay and gets converted into ³⁵Cl.
They used ³⁵S for radioactive labeling of the protein coat of the bacteriophage. It helped them to trace the movement or transfer of protein efficiently.
