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:
viral disease
Q: Answer the following question given this paragraph: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ). Q: Warming up your body before a workout does what to the blood flow? Choices: - reduces it - stops it - minimizes it - increases it A:
A: increases it
Question: Answer the following question given this paragraph: Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The chapter on atoms, molecules, and ions introduced the basic idea of nuclear structure, that the nucleus of an atom is composed of protons and, with the exception of 11 H, neutrons. Recall that the number of protons in the nucleus is called the atomic number (Z) of the element, and the sum of the number of protons and the number of neutrons is the mass number (A). Atoms with the same atomic number but different mass numbers are isotopes of the same element. When referring to a single type of nucleus, we often use the term nuclide and identify it by the notation A where X is the symbol Z X, 14 Often a nuclide is referenced 6 C. example, 146 C is called "carbon-14. Q: Atoms with the same atomic number but different mass numbers are called what? Choices: - tropes - organisms - reactions - isotopes A:
Answer: isotopes
*Question*
Answer the following question given this paragraph: The active transport of ions across the membrane causes an electrical gradient to build up across the plasma membrane. The number of positively charged ions outside the cell is greater than the number of positively charged ions in the cytosol. This results in a relatively negative charge on the inside of the membrane, and a positive charge on the outside. This difference in charges causes a voltage across the membrane. Voltage is electrical potential energy that is caused by a separation of opposite charges, in this case across the membrane. The voltage across a membrane is called membrane potential . Membrane potential is very important for the conduction of electrical impulses along nerve cells. Q: The active transport of ions across the membrane causes an electrical gradient to build up across the what? Choices: - colloidal membrane - components membrane - cells membrane - plasma membrane A:
**Answer**
plasma membrane
Q: Answer the following question given this paragraph: Water droplets form when the air reaches 100% humidity. If the temperature is cold enough, frost will form. Q: Water droplets form when the air reaches 100-percent what? Choices: - density - chance of rain - heat - humidity A:
A: humidity
