Q: What is the colorless gas with a sharp, pungent odor used in smelling salts? Read this paragraph and choose the correct option from the provided answers: Ammonia is a colorless gas with a sharp, pungent odor. Smelling salts utilize this powerful odor. Gaseous ammonia readily liquefies to give a colorless liquid that boils at 33 C. Due to intermolecular hydrogen bonding, the enthalpy of vaporization of liquid ammonia is higher than that of any other liquid except water, so ammonia is useful as a refrigerant. Ammonia is quite soluble in water (658 L at STP dissolves in 1 L H2O). The chemical properties of ammonia are as follows: 1. Ammonia acts as a Brnsted base, as discussed in the chapter on acid-base chemistry. The ammonium ion is. Choices: - nitrogen - hydrogen - helium - ammonia A:
ammonia

Q: Q: What do scientists use to help explain objects or systems in simpler ways? Read this paragraph and choose the correct option from the provided answers: Scientists use models to help them understand and explain ideas. Models explain objects or systems in a more simple way. Models often only show only a part of a system. The real situation is more complicated. Models help scientists to make predictions about complex systems. Some models are something that you can see or touch. Other types of models use an idea or numbers. Each type is useful in certain ways. Choices: - theories - measurements - plants - models A:
A: models

Question: Q: What is the organ that senses sound? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - nose - eye - skin - ear A:
Answer: ear

Q: What is released from the body during ejaculation? Read this paragraph and choose the correct option from the provided answers: Sperm are released from the body during ejaculation . Ejaculation occurs when muscle contractions propel sperm from the epididymis. The sperm are forced through the ducts and out of the body through the urethra. As sperm travel through the ducts, they mix with fluids from the glands to form semen. Hundreds of millions of sperm are released with each ejaculation. Choices: - saliva - urine - blood - sperm A:
**Answer**
sperm

You can see a human skeleton as an example of the vertebrate endoskeleton in Figure below . In addition to the vertebral column, the vertebrate endoskeleton includes:. Choices: - structural skeleton - exoskeleton - deep skeleton - internal skeleton A:
(Answer)
internal skeleton
