Phospholipids form the main structure of cell membrane called lipid bilayer.
Answer:
The expression of genes associated with drug resistance leads to the reduction in the effectiveness of drugs against cancer cells.
Explanation:
In cancer, drug resistance is produced when oncogenic cells are able to develop mechanisms of resistance against drugs such as, for example, chemotherapeutic agents. In these cases, therapeutic treatments become ineffective to fight against cancer cells and tumor progression. In consequence, it is imperative to trace the expression of target oncogenes associated with drug resistance in order to provide effective treatments to eliminate cancer cells.
Two species of finches found on the same galápagos island but feeding on different food sources is an example of sympatric speciation.
<h3>What is speciation?</h3>
Speciation is the evolutionary process that leads to reproductive isolation and eventually to the emergence of new species.
Sympatric speciation refers to the emergence of reproductive barriers in individuals of the same species that inhabit the same region, whereas allopatric speciation occurs in individuals separated by geographic barriers.
In conclusion, two species of finches found on the same galápagos island but feeding on different food sources is an example of sympatric speciation.
