Question

if you hold your breath for a long time, how does that affect homeostasis in your body?
it disrupts homeostasis because oxygen builds up in your blood
it disrupts homeostasis because carbon dioxide builds up in your blood
it maintains homeostasis because your carbon dioxide levels remain constant

Explanation:

During normal breathing, oxygen is taken in and carbon - dioxide is exhaled. When you hold your breath, carbon dioxide produced by the body's cells cannot be exhaled. As a result, carbon dioxide builds up in the blood, which disrupts the body's internal balance or homeostasis. Oxygen does not build up in the blood during breath - holding as the body continues to consume oxygen.

Answer:

it disrupts homeostasis because carbon dioxide builds up in your blood
