Here are the answers to your questions based on the concepts of homeostasis and physiology:
-
How does a marine iguana maintain homeostasis despite ingesting large amounts of salt with its food?
- Correct Answer: Marine iguanas throw up large amounts of salt. Marine iguanas have specialized glands that allow them to excrete excess salt from their bodies, primarily by expelling it through their nostrils, which is often noted as "sneezing." However, the most direct answer to the ingestion of large amounts of salt is that they can vomit and excrete it through this process.
-
How does the human body prevent internal energy levels from becoming too low?
- Correct Answer: The brain transmits feelings of hunger to the digestive system, which initiates eating. The brain's regulation of hunger and fullness is a key element of energy balance, signaling the need to consume food when energy levels are low.
-
How does the body react to cold temperature?
- Correct Answer: Your body shivers to help it maintain homeostasis. Shivering is a physiological response that generates heat to help maintain the body's internal temperature when exposed to cold.
-
Which statement describes homeostasis?
- Correct Answer: It is a process of maintaining an internal state of balance for an organism. Homeostasis refers to the mechanisms that organisms use to maintain stable internal conditions despite changes in the external environment.
