What else can I help you with?
Many organisms take magnesium from saewater to make bones or shells true or false?
true
Many ocean creatures make their shells out of calcium carbonate (CaCO3). This process is more difficult when the ocean pH is lower. Why would greenhouse gas emissions harm these creatures?
Greenhouse gas emissions increase levels of carbon dioxide in the atmosphere, which leads to ocean acidification when CO2 is absorbed by the ocean. This lowers the pH of seawater, making it harder for marine organisms like shell-forming creatures to extract the calcium carbonate they need to build their shells. This can weaken their shells and make them more vulnerable to damage and predators.
How much muscles and bones work together to make organisms move?
muscels pull the bone
Why are large areas of sea floor covered with thick layers of sediment containing calcium?
Large areas of sea floor are covered with thick layers of sediment containing calcium due to the accumulation of calcium carbonate shells and skeletons from marine organisms over time. This process, known as biomineralization, contributes to the formation of limestone and other calcium-rich sediments.
What ion makes up 7.7 percent of the ions in seawater?
Magnesium ions make up approximately 7.7 percent of the ions in seawater. These ions play a key role in various biological processes and are important for the health of marine organisms.
Marine organisms such as coral and shellfish have carbon in their bodies in what forms?
Marine organisms such as coral and shellfish have carbon in their bodies in the form of calcium carbonate, which makes up their shells and skeletons. Additionally, they also contain carbon in organic molecules such as proteins, lipids, and carbohydrates that are essential for their growth and metabolism. The carbon in these organisms ultimately comes from carbon dioxide in the surrounding seawater, which they assimilate through processes like photosynthesis and feeding.
What is process used to make seawater drinkable by removing the salt?
Desalination Dawg also reffered to as removing salt from the seawater to make it drinkable
What did stone age people use to make jewelry?
Stone age people used a variety of materials to make jewelry, including shells, bones, teeth, and stones. They would pierce these materials to create beads or pendants, which they could then string together to make necklaces or bracelets. These jewelry items held cultural significance and were often used as symbols of status or for decorative purposes.
What should you do with all your shells?
Make the shells into a necklace.
Does seawater make dyed hair green?
yes
What is the mistake in this statement magnesium and chloride make up most of the ions in seawater?
It should say, "Magnesium and CHLORINE make up most of the ions in seawater." Not chloride.
What conclusion can you make from comparing the bones in a bird wing... a bat wing and a pterodactyl wing?
These organisms share a common ancestor with each other.
