Q: Carbon atoms are bonded to as many hydrogen atoms as possible in what type of fatty acids? Read this paragraph and choose the correct option from the provided answers: Saturated fatty acids have only single bonds between carbon atoms. As a result, the carbon atoms are bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogens. Saturated fatty acids are found in fats. Choices: - super - unsaturated - oily - saturated A:
(Answer)
saturated

Ques: Q: By what process does oxygen enter the pores of flatworms? Read this paragraph and choose the correct option from the provided answers: Flatworms do not have a respiratory system.

Q: What are the two main minerals found in ocean water? Read this paragraph and choose the correct option from the provided answers: Have you ever gone swimming in the ocean? If you have, then you probably tasted the salts in the water. By mass, salts make up about 3.5% of ocean water. The table below shows the most common minerals in ocean water ( Table below ). The main components are sodium and chloride. Together they form the salt known as sodium chloride. You may know the compound as table salt or the mineral halite. Choices: - dioxide , chloride - quartz, carbon - carbon , chloride - sodium, chloride A:
(A).
sodium, chloride

Ques:Q: Compounds like sodium chloride form structures called what? Read this paragraph and choose the correct option from the provided answers: Compounds like sodium chloride form structures called crystals. A crystal is a rigid framework of many ions locked together in a repeating pattern. Ions are electrically charged forms of atoms. You can see a crystal of sodium chloride in the Figure below . It is made up of many sodium and chloride ions. Choices: - ions - microorganisms - hydrocarbons - crystals A:

Ans:crystals
