Answer:
The correct answer is: B.Marine iguanas sneeze excess salt out of their bodies.
Explanation:
Osmotic balance is a huge part of maintaining homeostasis. Since marine iguanas ingest large amounts of salt with its food, the risk of osmotic imbalance would be big if these animals wouldn't be able to get rid of the salt (because salt drags water with it, and the constant salt ingestion would eventually lead to dehydration).
To prevent this life-threatening risk, marine iguanas sneeze the excess salt. This way they can dispose of salt without losing any water.
The excessive amount of salt that travels through the iguana's bloodstream is collected in a <u>gland</u> that marine iguanas have above their eyes. Through this gland, iguanas "sneeze" the unwanted salt out.

The answer is E- All answers are correct
Explanation:
Serfs in the middle ages were peasant farmers who provided manual labor in their master’s land who in return allowed them the right to cultivate certain fields within the manor in order to maintain themselves and were entitled to protection. As they worked a plot of land they were also required to work for the owner of the land (who was called the Lord of the Manor) It was a condition of debt bondage and indentured servitude. They were not allowed to leave the land they were bound to, if they did they would pay a fine. They were also required to pay an inheritance tax.
Some of their obligations included;
- Payment of taxes and fees in addition to their services.
- Payment of dues in form of labor in order to be able to use part of the Lord's field to generate their food and sustain themselves.
- Working the land a few days a week (at least three) and longer during special seasons like plantation and harvest.
