Answer the following question given this paragraph: An ionic crystal lattice breaks apart when it is dissolved in water. Dissociation is the separation of ions that occurs when a solid ionic compound dissolves. It is important to be able to write dissociation equations. Simply undo the crisscross method that you learned when writing chemical formulas of ionic compounds. The subscripts for the ions in the chemical formulas become the coefficients of the respective ions on the product side of the equation. Shown below are dissociation equations for NaCl, Ca(NO 3 ) 2 , and (NH 4 ) 3 PO 4 . Q: What do you call the separation of ions that occurs when a solid ionic compound dissolves? Choices: - deformation - decomposition - dissolution - dissociation A:
dissociation
Answer the following question given this paragraph: In the single fixed pulley, only one rope segment pulls up on the load, so the ideal mechanical advantage is 1. In other words, this type of pulley doesn't increase the force that is applied to it. However, it does change the direction of the force. This allows you to use your weight to pull on one end of the rope and more easily raise the load attached to the other end. Q: What is the ideal mechanical advantage in the single fixed pulley? Choices: - zero - 2 - 4 - 1 A:
1
Q: Answer the following question given this paragraph: The Hubble space telescope shows that technology and science are closely related. Technology uses science to solve problems, and science uses technology to make new discoveries. However, technology and science have different goals. The goal of science is to answer questions and increase knowledge. The goal of technology is to find solutions to practical problems. Although they have different goals, science and technology work hand in hand, and each helps the other advance. Scientific knowledge is used to create new technologies such as the space telescope. New technologies often allow scientists to explore nature in new ways. Q: What is the goal of science? Choices: - improve knowledge - improve life expectancy - gain scholarships - increase knowledge A:
A: increase knowledge
Question: Answer the following question given this paragraph: Q: Thousands of receptor cells that detect the sex attractant equip each filament of what structure? Choices: - optic nerve - flagella - molecule - antenna A:
Answer: antenna

Answer the following question given this paragraph: Hearing is the ability to sense sound waves, and the ear is the organ that senses sound. Sound waves enter the auditory canal and travel to the eardrum (see Figure below ). They strike the eardrum and make it vibrate. The vibrations then travel through several other structures inside the ear and reach the cochlea. The cochlea is a coiled tube filled with liquid. The liquid moves in response to the vibrations, causing tiny hair cells lining the cochlea to bend. In response, the hair cells send nerve impulses to the auditory nerve , which carries the impulses to the brain. The brain interprets the impulses and "tells" us what we are hearing. Q: What is the organ that senses sound? Choices: - nose - eye - skin - ear A:
**Answer**
ear
Answer the following question given this paragraph: What is the source of glucose for living things? It is made by plants and certain other organisms. The process in which glucose is made using energy in light is photosynthesis . This process requires carbon dioxide and water. It produces oxygen in addition to glucose. Q: What is the process in which glucose is made using energy in light called? Choices: - glucosynthesis - photogenesis - gluconeogenesis - photosynthesis A:
photosynthesis
