Answer the following question given this paragraph: Eukaryotic cells contain special compartments surrounded by membranes, called organelles. For example, notice in this image the mitochondria, lysosomes, and Golgi apparatus. Q: What are the special compartments that are surrounded by membranes inside eukaryotic cells called? Choices: - ribosomes - vacuoles - chloroplasts - organelles A:
organelles
Answer the following question given this paragraph: Mutualism is a symbiotic relationship in which both species benefit. An example of mutualism is pictured in Figure below . The clownfish in the photo is hiding among the tentacles of a sea anemone. The tentacles have stingers that can inject poison in the anemone's prey. The clownfish is protected from the stingers by mucus that covers its body. Q: Mutualism is a symbiotic relationship in which both species do what? Choices: - die - suffer - reproduce - benefit A:
benefit
Q: Answer the following question given this paragraph: Flatworms have a mesoderm cell layer and simple organ systems. They also show cephalization and bilateral symmetry. Q: What type of cell layer do flatworms have? Choices: - epidermis - cuticle - endoderm - mesoderm A:
A: mesoderm
Question: Answer the following question given this paragraph: Since eddy currents and magnetic damping occur only in conductors, recycling centers can use magnets to separate metals from other materials. Trash is dumped in batches down a ramp, beneath which lies a powerful magnet. Conductors in the trash are slowed by magnetic damping while nonmetals in the trash move on, separating from the metals. (See Figure 23.17. ) This works for all metals, not just ferromagnetic ones. A magnet can separate out the ferromagnetic materials alone by acting on stationary trash. Q: Since eddy currents and magnetic damping occur only in conductors, recycling centers can use these to separate metals from other materials? Choices: - particles - cranes - alloys - magnets A:
Answer: magnets

Answer the following question given this paragraph: Natural selection occurs when there are differences in fitness among members of a population. Q: Differences in fitness among different members of a population can lead to what kind of selection? Choices: - fluid selection - subliminal selection - origin selection - natural selection A:
**Answer**
natural selection
Q: Answer the following question given this paragraph: Significant figures are all of the digits that can be known with certainty in a measurement plus an estimated last digit. Significant figures provide a system to keep track of the limits of the original measurement. To record a measurement, you must write down all the digits actually measured, including measurements of zero, and you must not write down any digit not measured. The only real difficulty with this system is that zeros are sometimes used as measured digits, while other times they are used to locate the decimal point. Q: What are all of the digits that can be known with certainty in a measurement plus an estimatied last digit called? Choices: - determined figures - important figures - miniature figures - significant figures A:
A: significant figures
