Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.

Answer:
The new drug will not be effective against the treatment of cancer.
Explanation:
The drug will not be effective against the cancer treatment because the drug will inhibit the dimerization of receptor tyrosine kinase (RTK) but as the Ras has undergone mutation due to replacement of one amino acid, it will be constitutively expressed and the drug is not effective in stopping the Ras functioning.
Thus, Gefitinib cannot work against the cancerous cell as it is not potent to stop the functioning of mutant Ras protein.
Igneous rocks are formed by hot melted magma coming from the Earth's core that crystalizes when gets in contact with air. They can be either intrusive or extrusive. B) <em>Large mineral crystals.</em>
<h3>
What is the igneous rock?</h3>
These rocks come straight from the interior of the Earth.
A liquid mass of silicate composition comes from the Earth's core. This melted mass comes at an extremely high temperature.
Magma begins to cool and solidify during its ascent to the Earth's surface. It solidifies and crystallizes into igneous rock following the magnetic field orientation.
Thre are two types of igneous rocks
• plutonic rocks ⇒ in areas close to the terrestrial crust ⇒ intrusive
• volcanic rocks ⇒ on the surface ⇒ extrusive
According to this description, the correct option is B. <em>Large mineral </em><em>crystals</em><em>.</em>
