How does a marine iguana maintain homeostasis despite ingesting large amounts of salt with its food?
Marine iguanas sneeze excess salt out of their bodies
Marine iguanas pass large amounts of salt through their urine
Marine iguanas throw up large amounts of salt
Marine iguanas sweat a lot to get rid of the extra salt
Marine iguanas maintain homeostasis despite ingesting large amounts of salt with their food by sneezing excess salt out of their bodies.
Marine iguanas have specialized glands located in their nasal passages that help excrete excess salt. These glands produce a concentrated brine solution that is excreted through their nostrils when they sneeze. This sneezing behavior allows them to expel the excess salt and maintain a balanced internal salt concentration.

Edwin buys a water bottle, reuses it twice, and then recycles it. Eleanor buys a water bottle, reuses it twelve times, and then throws it away.
Which energy cost would apply to Edwin, but not to Eleanor?
(1 point)
Responses
the cost of transporting the bottle to the store
the cost of transporting the bottle to the store
the cost of transporting the bottle away from the house
the cost of transporting the bottle away from the house
the cost of producing the original bottle
the cost of producing the original bottle
the cost of processing the bottle after it was no longer used
The energy cost that would apply to Edwin, but not to Eleanor, is the cost of transporting the bottle away from the house. Since Edwin recycles the bottle after reusing it twice, it would require additional energy for transportation to the recycling facility. Eleanor, on the other hand, throws the bottle away after reusing it twelve times, so there is no additional transportation cost involved in her case.
Um pls put it in short form
The energy cost that applies to Edwin, but not to Eleanor, is the cost of transporting the bottle away from the house.

Ocean waves are a source of energy. In 1–2 sentences, make and justify a claim about whether ocean waves are a renewable or nonrenewable resource.
Ocean waves are a renewable resource because they are generated by natural forces such as wind and tides, which are ongoing and constantly replenished in nature. This allows for a continuous supply of ocean waves that can be harnessed for energy without depletion.
In three to five sentences, explain the effects of acid rain on the environment
Acid rain, caused by pollutants like sulfur dioxide and nitrogen oxide reacting with water vapor in the atmosphere, has detrimental effects on the environment. Firstly, it can harm aquatic ecosystems by increasing the acidity of lakes, rivers, and streams, leading to the decline of fish populations and other aquatic organisms. Additionally, acid rain damages forests and vegetation by leaching nutrients from the soil, making it difficult for plants to grow and thrive. It also corrodes buildings, statues, and other structures made of stone or metal, causing erosion and deterioration. Overall, the effects of acid rain on the environment are far-reaching and have cascading impacts on various ecosystems.
Larger companies often need many workers who do different steps in the transportation process, instead of each member doing all steps in the process they do a single step before handing it to another worker to do the next step.
Imagine that you are the head of a large company that wants to retrieve raw materials. In three to five sentences, describe three different jobs your company may need and explain the purpose of those jobs.
As the head of a large company retrieving raw materials, three different jobs that may be needed are:
1. Procurement Manager: This role is responsible for sourcing and acquiring the necessary raw materials from suppliers. They ensure the materials meet quality standards, negotiate contracts, and maintain strong relationships with vendors. The procurement manager's purpose is to effectively manage the supply chain, ensure timely access to raw materials, and optimize costs.
2. Logistics Coordinator: This position oversees the transportation and delivery of raw materials from suppliers to the company's facilities. They coordinate shipping schedules, arrange for carriers, track shipments, and handle any logistical challenges. The logistics coordinator's purpose is to ensure smooth and efficient movement of materials, avoiding delays or disruptions in the supply chain.
3. Warehouse Manager: This role involves overseeing the storage, organization, and inventory management of raw materials within the company's warehouse. The warehouse manager tracks stock levels, coordinates with other departments for material requests, and ensures proper storage conditions. Their purpose is to maintain an organized and efficient warehouse operation, enabling easy access to raw materials when needed and minimizing wastage or loss.
These three jobs collectively contribute to the successful and streamlined retrieval of raw materials, ensuring a steady supply for production processes within the company's operations.
