Q: The most common substance on earth, water, is primarily present in what state? Read this paragraph and choose the correct option from the provided answers: Water is the most common substance on Earth, and most of it exists in the liquid state. A liquid is one of four well-known states of matter, along with solid, gas, and plasma states. The particles of liquids are in close contact with each other but not as tightly packed as the particles in solids. The particles can slip past one another and take the shape of their container. However, they cannot pull apart and spread out to take the volume of their container, as particles of a gas can. If the volume of a liquid is less than the volume of its container, the top surface of the liquid will be exposed to the air, like the vinegar in the bottle pictured in the Figure below . Choices: - gas - solid - freshwater - liquid A:
(Answer)
liquid

Q: What are joints in which the bones are connected by a band of connective tissue? Read this paragraph and choose the correct option from the provided answers: Syndesmoses are joints in which the bones are connected by a band of connective tissue, allowing for more movement than in a suture. An example of a syndesmosis is the joint of the tibia and fibula in the ankle. The amount of movement in these types of joints is determined by the length of the connective tissue fibers. Gomphoses occur between teeth and their sockets; the term refers to the way the tooth fits into the socket like a peg (Figure 38.24). The tooth is connected to the socket by a connective tissue referred to as the periodontal ligament. Choices: - cartilaginous - saddle - plane - syndesmoses A:
(Answer)
syndesmoses

Q: What may the jointed appendages of arthropods be used for? Read this paragraph and choose the correct option from the provided answers: The jointed appendages of arthropods may be used as legs for walking. Being jointed makes them more flexible. Try walking or climbing stairs without bending your knees, and you'll see why joints are helpful. In most arthropods, the appendages on the head have been modified for other functions. Figure below shows some of the head appendages found in arthropods. Sensory organs such as eyes are also found on the head. Choices: - jumping - crawling - digging - walking A:
(Answer)
walking
