Question

the study of life
adaptations and homeostasis in arctic animals
passage:
scientists studied various organisms in the arctic to understand how they maintain homeostasis and adapt to extreme conditions. they focused on three species: arctic foxes, snow hares, and arctic bacteria.
study 1: seasonal changes researchers tracked physical changes in arctic foxes and snow hares across seasons.
table 1: seasonal adaptations

season	fox fur color	fox fur thickness (mm)	hare fur color	hare fur thickness (mm)
fall	mixed	25	mixed	20
winter	white	35	white	30
spring	mixed	20	mixed	15

study 2: response to temperature changes scientists monitored body temperature regulation in arctic foxes.
figure 1: fox body temperature response to environmental changes
temperature response in arctic fox

	body temperature	environmental temp
3	37	37
6	38	38
9	37	37
12	36	36

study 3: bacterial adaptation researchers studied arctic bacteria populations exposed to different antibiotics over time.

1. the body temperature pattern in figure 1 demonstrates that arctic foxes:

cannot survive cold temperatures
only regulate temperature during summer
maintain homeostasis despite environmental changes
dont respond to environmental stimuli

Explanation:

The passage describes how Arctic foxes' body - temperature regulation is monitored in response to environmental changes. The graph shows that despite fluctuations in environmental temperature, the body temperature of Arctic foxes remains relatively stable, which indicates they maintain homeostasis.

Answer:

Maintain homeostasis despite environmental changes
