Answer the following question given this paragraph: cell that transmits electrical impulses in the nervous system; commonly called nerve cell. Q: What type of cell transmits electrical impulses in the nervous system? Choices: - toxin cell - Large Cell - trace cell - nerve cell A:
nerve cell
Answer the following question given this paragraph: All mammals have lungs that are the main organs for breathing. Lung capacity has evolved to support the animal's activities. During inhalation, the lungs expand with air, and oxygen diffuses across the lung's surface and enters the bloodstream. During exhalation, the lungs expel air and lung volume decreases. In the next few sections, the process of human breathing will be explained. Q: What are the main organs for breathing in a mammal? Choices: - gills - nostrils - intestines - lungs A:
lungs
Q: Answer the following question given this paragraph: The Cytoskeleton Much like the bony skeleton structurally supports the human body, the cytoskeleton helps the cells to maintain their structural integrity. The cytoskeleton is a group of fibrous proteins that provide structural support for cells, but this is only one of the functions of the cytoskeleton. Cytoskeletal components are also critical for cell motility, cell reproduction, and transportation of substances within the cell. The cytoskeleton forms a complex thread-like network throughout the cell consisting of three different kinds of proteinbased filaments: microfilaments, intermediate filaments, and microtubules (Figure 3.18). The thickest of the three is the microtubule, a structural filament composed of subunits of a protein called tubulin. Microtubules maintain cell shape and structure, help resist compression of the cell, and play a role in positioning the organelles within the cell. Microtubules also make up two types of cellular appendages important for motion: cilia and flagella. Cilia are found on many cells of the body, including the epithelial cells that line the airways of the respiratory system. Cilia move rhythmically; they beat constantly, moving waste materials such as dust, mucus, and bacteria upward through the airways, away from the lungs and toward the mouth. Beating cilia on cells in the female fallopian tubes move egg cells from the ovary towards the uterus. A flagellum (plural = flagella) is an appendage larger than a cilium and specialized for cell locomotion. The only flagellated cell in humans is the sperm cell that must propel itself towards female egg cells. Q: In humans, the sperm cell is the only cell with what structure that enables motility? Choices: - eukaryotic - False Cell - sporangia - flagella A:
A: flagella
Question: Answer the following question given this paragraph: Q: Snippet 3: the diploid cells resulting from karyogamy are short-lived and undergo meiosis, producing what? Choices: - binary spores - hyperactive spores - stunted spores - haploid spores A:
Answer: haploid spores

Answer the following question given this paragraph: Figure 17.6 In influenza virus infection, glycoproteins attach to a host epithelial cell. As a result, the virus is engulfed. RNA and proteins are made and assembled into new virions. Q: Influenza is a type of what, where glycoproteins attach to a host epithelial cell? Choices: - recent disease - nucleus disease - atoms disease - viral disease A:
**Answer**
viral disease

Answer the following question given this paragraph: The hint of symmetry between electricity and magnetism found in the preceding chapter will be elaborated upon in this chapter. Specifically, we know that a current creates a magnetic field. If nature is symmetric here, then perhaps a magnetic field can create a current. The Hall effect is a voltage caused by a magnetic force. That voltage could drive a current. Historically, it was very shortly after Oersted discovered currents cause magnetic fields that other scientists asked the following question: Can magnetic fields cause currents? The answer was soon found by experiment to be yes. In 1831, some 12 years after Oersted's discovery, the English scientist Michael Faraday (17911862) and the American scientist Joseph Henry (17971878) independently demonstrated that magnetic fields can produce currents. The basic process of generating emfs (electromotive force) and, hence, currents with magnetic fields is known as induction; this process is also called magnetic induction to distinguish it from charging by induction, which utilizes the Coulomb force. Today, currents induced by magnetic fields are essential to our technological society. The ubiquitous generatorfound in automobiles, on bicycles, in nuclear power plants, and so onuses magnetism to generate current. Other devices that use magnetism to induce currents include pickup coils in electric guitars, transformers of every size, certain microphones, airport security gates, and damping mechanisms on sensitive chemical balances. Not so familiar perhaps, but important nevertheless, is that the behavior of AC circuits depends strongly on the effect of magnetic fields on currents. Q: What does the ubiquitous generator use to generate currents? Choices: - inertia - water - gravity - magnetism A:
**Answer**
magnetism
