Question

the unique yeti crab lives in a very specific range around the vents. what is the reason for this highly restricted habitat range?
the risk of being boiled if too close, or dying of hypothermia if too far.
to take advantage of the lower pressure in that specific area.
to stay close to its primary food source, symbiotic tubeworms.
to avoid predators, who cannot enter this specific zone

what are the primary anthropogenic influences on hydrothermal vent?
scientific research (physical disturbance and contamination) and the potential for commercial mining
noise pollution from shipping and commercial fishing.

Explanation:

First Question (Yeti Crab Habitat Range)

Yeti Crabs live near hydrothermal vents. The key is their thermal tolerance: too close to vents (high temp) risks boiling, too far (cold) risks hypothermia. Other options: lower pressure isn't a main factor, tubeworms are not their primary food (they farm bacteria), and avoiding predators isn't the main habitat restriction driver.

Anthropogenic (human - caused) influences on hydrothermal vents: Scientific research disturbs/ contaminates, and commercial mining is a potential threat. Noise from shipping/ fishing doesn't impact vents as much (vents are deep, shipping/fishing noise less relevant there).

Answer:

A. The risk of being boiled if too close, or dying of hypothermia if too far.
