In which situation can both chemical control and nervous control be seen?
Answer and explanation
Correct answer: Becoming alert after seeing danger and increase in adrenaline secretion
Seeing danger begins with sensory receptors and nervous pathways, which rapidly alert the brain and coordinate an immediate response. At the same time, the adrenal glands may release more adrenaline into the blood, producing chemical or hormonal effects such as increased heart rate and readiness for action. Therefore option A demonstrates both forms of control. The other examples describe plant growth responses without this combined animal coordination.
