Answer the following question given this paragraph: Ether molecules have an oxygen atom and can engage in hydrogen bonding with water molecules. An ether molecule has about the same solubility in water as the alcohol that is isomeric with it. Q: Ether molecules have an oxygen atom and can engage in hydrogen bonding with which other molecules? Choices: - carbon dioxides - proteins - lipids - water A:
water
Q: Answer the following question given this paragraph: Cleaning groundwater in an aquifer requires bioremediation or chemical remediation. Bioremediation uses microorganisms to consume a pollutant. Chemical remediation destroys the contaminant. Q: What do you call a process that uses microorganisms to consume a pollutant? Choices: - siltation - filtration - biodegradation - bioremediation A:
A: bioremediation
Question: Answer the following question given this paragraph: Some predator species are known as keystone species. A keystone species is one that plays an especially important role in its community. Major changes in the numbers of a keystone species affect the populations of many other species in the community. For example, some sea star species are keystone species in coral reef communities. The sea stars prey on mussels and sea urchins, which have no other natural predators. If sea stars were removed from a coral reef community, mussel and sea urchin populations would have explosive growth. This, in turn, would drive out most other species. In the end, the coral reef community would be destroyed. Q: What is a species that plays an especially important role in it's community called? Choices: - complement - Invasive - Leader - keystone A:
Answer: keystone

Answer the following question given this paragraph: Unsaturated fatty acids have at least one double bond between carbon atoms. As a result, some carbon atoms are not bonded to as many hydrogen atoms as possible. They are unsaturated with hydrogens. Unsaturated fatty acids are found in oils. Q: Where are unsaturated fatty acids commonly found? Choices: - animal products - butter - fish - oil A:
**Answer**
oil

Answer the following question given this paragraph: Steroid hormones are made of lipids, such as phospholipids and cholesterol. They are fat soluble, so they can diffuse across the plasma membrane of target cells and bind with receptors in the cytoplasm of the cell (see Figure below ). The steroid hormone and receptor form a complex that moves into the nucleus and influences the expression of genes, essentially acting as a transcription factor. Examples of steroid hormones include cortisol and sex hormones. Q: What are steroid hormones made of? Choices: - water - amino acid - organisms - lipids A:
**Answer**
lipids
