Question: Q: Synthetic and natural rubber, styrofoam and plastic are examples of organic what? Read this paragraph and choose the correct option from the provided answers: Polymers are a pervasive part of modern life. It is very likely that at least some part of your clothing is made of nylon, rayon, or polyester. The milk or juice that you have for breakfast often comes in a polyethylene container. If you don't have breakfast at home, you might get coffee from a fast food establishment, where your order is delivered to you in a Styrofoam®️ container. While getting out of your car, you bang the door on another vehicle. One reason you may not have dented the door is the fact that it could be made out of a polymeric plastic material that resists deformation more than simple metallic structures. Elsewhere on your car, both synthetic and natural rubber are probably present in the tires. All these materials are examples of organic polymers. Choices: - solutions - microbes - metals - polymers A:
Answer: polymers

Question: Q: What type of proteins are only temporarily associated with the membrane? Read this paragraph and choose the correct option from the provided answers: Peripheral membrane proteins are proteins that are only temporarily associated with the membrane. They can be easily removed, which allows them to be involved in cell signaling. Peripheral proteins can also be attached to integral membrane proteins, or they can stick into a small portion of the lipid bilayer by themselves. Peripheral membrane proteins are often associated with ion channels and transmembrane receptors. Most peripheral membrane proteins are hydrophilic. Choices: - visual membrane proteins - sensitive rod proteins - peripheral oxidation proteins - peripheral membrane proteins A:
Answer:
peripheral membrane proteins
