Answer
The most suitable choice of process and description is thus option d.<br /><br />### Process (1): mitosis<br />### Description (2): not be inherited by the children of the sunbather
Explain
## Step1: <br />Meiosis and Mitosis are two modes of cell division. While \"mitosis\" results in two genetically identical daughter cells from a parent cell which is typically used for body tissue growth and recovery, \"meiosis\" is employed to produce reproductive cells - eggs or sperm - for sexual reproduction. <br /><br />## Step2: <br />If mutations occur in \"mitosis\", they remain confined inside the individual's body, and do not get passed onto next generations due to its role in nonreproductive/somatic cells, i.e., they do not impact the cells used in sexual reproduction (germ cells). <br /><br />## Step3: <br />Contrarily, if mutations occur during \"meiosis\", they can be potentially passed onto the offspring, noting that this process involves reproductive cells.<br /><br />## Step4: <br />In while, following the prolonged exposure to the sun scenario, it is DNA found in the skin cells that will mutate. The sunbather's skin cells are nonreproductive / somatic cells, the mitosis modality is what passes mutations along to the daughter cells.<br /><br />## Step5: <br />However, these mitotic mutations won't be passed onto offspring as stated previously that it only propagates within an individual's nonreproductive cells.
