The correct answer is: the nervous system and the endocrine system.
Explanation:
Homeostasis is the state in which the body maintains itself in order to operate accordingly. If homeostasis fails, diseases occur. There are many factors that are important to maintain in a range of normality, like body temperature, pH, and ion concentration.
In order to maintain homeostasis, the nervous system and the endocrine system intervene to regulate the factors mentioned above.
The nervous system makes use of neurotransmitters, which are molecules that are transmitted through nervous impulses and that carry information that is capable of exciting or inhibiting different cells and processes.
The endocrine system maintains homeostasis by producing and transporting hormones (made by endocrine glands) that reach specific cells and trigger specific reactions.
For example, when the body is losing too much water due to heavy exercise, the pituitary gland produces the hormone ADH, which will act on the kidney to produce reabsorption of water that will also concentrate the urine.
The correct answer is B.
Global warming encourages other fox species to spread into areas previously unsuited to them. This increase in fox populations, and also change in environment, will reduce the amount of prey available in the area.
Oxygen availability will not be impacted enough to cause the arctic foxes to suffocate. If it did, humans would be at risk too!
