Read this paragraph and choose the correct option from the provided answers: the current. Capacitors can be used to filter out low frequencies. For example, a capacitor in series with a sound reproduction system rids it of the 60 Hz hum. Choices: - white noise - vibration - echo - hum A:
Answer: hum

Question: Q: All living cells in multicellular organisms contain an internal cytoplasmic compartment, and a nucleus within the cytoplasm. cytosol, the jelly-like substance within the cell, provides the fluid medium necessary for this? Read this paragraph and choose the correct option from the provided answers: Now that you have learned that the cell membrane surrounds all cells, you can dive inside of a prototypical human cell to learn about its internal components and their functions. All living cells in multicellular organisms contain an internal cytoplasmic compartment, and a nucleus within the cytoplasm. Cytosol, the jelly-like substance within the cell, provides the fluid medium necessary for biochemical reactions. Eukaryotic cells, including all animal cells, also contain various cellular organelles. An organelle ("little organ") is one of several different types of membrane-enclosed bodies in the cell, each performing a unique function. Just as the various bodily organs work together in harmony to perform all of a human's functions, the many different cellular organelles work together to keep the cell healthy and performing all of its important functions. The organelles and cytosol, taken together, compose the cell's cytoplasm. The nucleus is a cell's central organelle, which contains the cell's DNA (Figure 3.13). Choices: - meiosis - cell division - apoptosis - biochemical reactions A:
Answer: biochemical reactions

Question: Q: The most common elements have the most tightly bound __________. Read this paragraph and choose the correct option from the provided answers: There are some noticeable spikes on the BE / A graph, which represent particularly tightly bound nuclei. These spikes reveal further details of nuclear forces, such as confirming that closed-shell nuclei (those with magic numbers of protons or neutrons or both) are more tightly bound. The spikes also indicate that some nuclei with even numbers for Z and N , and with Z = N , are exceptionally tightly bound. This finding can be correlated with some of the cosmic abundances of the elements. The most common elements in the universe, as determined by observations of atomic spectra from outer space, are hydrogen, followed by 4 He , with much smaller amounts of 12 C and other elements. It should be noted that the heavier elements are created in supernova explosions, while the lighter ones are produced by nuclear fusion during the normal life cycles of stars, as will be discussed in subsequent chapters. The most common elements have the most tightly bound nuclei. It is also no accident that one of the most tightly bound light nuclei is 4 He , emitted in decay. Choices: - quarks - membrane - atoms - nuclei A:
Answer:
nuclei
