Q: Answer the following question given this paragraph: Mirrors are made from highly reflective metal that is applied to a curved or flat piece of glass. Converging mirrors can be used to focus light headlights, telescopes, satellite TV receivers, and solar cookers all rely on this principle. Like lenses, mirrors can create images. Q: What objects are made from highly reflective metal that is applied to a curved or flat piece of glass? Choices: - frames - vases - machines - mirrors A:
A: mirrors
Question: Answer the following question given this paragraph: Figure 21.4 Viruses can be either complex in shape or relatively simple. This figure shows three relatively complex virions: the bacteriophage T4, with its DNA-containing head group and tail fibers that attach to host cells; adenovirus, which uses spikes from its capsid to bind to host cells; and HIV, which uses glycoproteins embedded in its envelope to bind to host cells. Notice that HIV has proteins called matrix proteins, internal to the envelope, which help stabilize virion shape. (credit "bacteriophage, adenovirus": modification of work by NCBI, NIH; credit "HIV retrovirus": modification of work by NIAID, NIH). Q: Hiv has proteins called what, internal to the envelope, which help stabilize virion shape? Choices: - reduction proteins - step proteins - sphere proteins - matrix proteins A:
Answer: matrix proteins
