Living species are alive and their species still have members, while extinct species no longer are living, and no more of their members exist.
The statement 'Skin cells and epithelial cells each make a different set of proteins, which determines each cell type's structure and function.' is correct. It is known as differentiation.
<h3>What is differentiation?</h3>
Differentiation refers to the cellular phenomenon for which different genes are expressed in specific cell types.
Differentiation leads to the formation of different cell types that have specific functions/roles.
Differentiation depends on gene expression pattern that influences the type and amount of proteins in a given cell.

Recombination is the method by which organisms can randomly assort their genotypes amongst each other to create offspring with a different haplotype than either of its parents. This can be done by either copying sequences from one homologous chromosome to another (no physical exchange) or crossing over (physical exchange.
Crossing over is a mechanism in eukaryotes by which recombination can occur, in which the two homologous chromosomes contributed by both parents literally cross over and break at certain points to exchange certain sections of the chromosomes amongst each together.
Self fertilizing organisms typically do not produce offspring that are genetically identical. However, this has an inbreeding effect on its offspring, since it is recombining from the same genotype and so has a higher chance of producing homozygous offspring. This is very detrimental for mammals and some eukaryotes, but in some other organisms such as bacteria, homozygosity is typically not an issue.
Answer:
Adaptive radiation
Explanation:
Adaptive radiation occurs when an ancestral species move to a new environment that has various resources that are necessary for survival and also has environmental conditions that would ensure its offspring adapt well over time. In this new environment, the ancestral species would produce offspring with different traits and behaviors that will allow them to survive in this new environment while occupying their various niches. Over a relatively short time, different species arising from the common ancestor would occupy the new environment.
