Answer:
The correct answer is option e. "result in permanent activation of Ras".
Explanation:
Ras function is regulated by the GTP/GDP cycling rate, in a way that Ras is inhibited by the substrate GDP. Once Ras hydrolyzes GTP, GDP is produced and Ras is inhibited by GDP. A mutation that inhibits Ras from hydrolyzing GTP, would lock Ras in a permanently activated state because no GDP would be produced and there will be no substrate to inhibit Ras.

Explanation:
A stimulus is something that provokes a response or reaction in a living organism. It can either be internal or external. An animal can respond to stimulus such as hunger, heat, predator etc.
However, among all the listed stimuli in the options, the PRESENCE OF A PREDATOR is most likely to result in a more rapid heartbeat in an animal. This is because the predator stimulus will require the animal to respond by running in order to survive. Running will increase its metabolic activity and cause its heartbeat to increase.
