Final Answer:
Apoptosis in adult organisms is generally involved in option a. organismal growth, option b. cell turnover, and option c. cell differentiation. Option E(A, B and C) is the answer.
Step-by-step explanation:
Apoptosis, or programmed cell death, serves crucial roles in maintaining tissue homeostasis in adult organisms. Option b correctly identifies apoptosis as being involved in cell turnover, where old or damaged cells undergo controlled death to be replaced by new ones, ensuring tissue integrity.
Additionally, apoptosis contributes to cell differentiation (option c), guiding the formation and shaping of tissues and organs during development and maintaining their structure in adulthood.
Moreover, apoptosis can play a role in organismal growth (option a), contributing to the shaping and sculpting of tissues and organs during development. Therefore, the correct answer is option e, as apoptosis is involved in organismal growth, cell turnover, and cell differentiation.
Option E is the answer.
