Answer the following question given this paragraph: Look at the battery and light bulb in Figure below . The light bulb works and it's connected to the battery, but it won't light. The problem is the loose wire on the left. It must be connected to the positive terminal of the battery in order for the bulb to light up. The reason? Electric current can flow through a material such as a wire only if the material forms a closed loop. Charges must have an unbroken path to follow between the positively and negatively charged parts of the voltage source, in this case, the battery. Q: Because charges must have an unbroken path to follow, electric current cannot flow through a material unless it forms what? Choices: - complete loop - closed area - total loop - closed loop A:
closed loop
Answer the following question given this paragraph: Q: What do you call the fragments of cells involved in the clotting process that are suspended in blood plasma? Choices: - hematocrit - ironites - hemoglobin - platelets A:
platelets
Q: Answer the following question given this paragraph: 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. Q: What type of proteins are only temporarily associated with the membrane? Choices: - visual membrane proteins - sensitive rod proteins - peripheral oxidation proteins - peripheral membrane proteins A:
A: peripheral membrane proteins
Question: Answer the following question given this paragraph: Q: What is the name for the inner lining of the uterus? Choices: - the uterine shell - the epidermis - cuticle - the endometrium A:
Answer: the endometrium

Answer the following question given this paragraph: Today, scientists think that electrons truly are fundamental particles that cannot be broken down into smaller, simpler particles. They are a type of fundamental particles called leptons. Protons and neutrons, on the other hand, are no longer thought to be fundamental particles. Instead, they are now thought to consist of smaller, simpler particles of matter called quarks. Scientists theorize that leptons and quarks are held together by yet another type of fundamental particles called bosons. All three types of fundamental particlesleptons, quarks, and bosonsare described below. The following Figure below shows the variety of particles of each type. Q: What can protons and neutrons be broken down into? Choices: - molecules - strings - ions - quarks A:
**Answer**
quarks
