Answer the following question given this paragraph: Materials that eject electrons when illuminated with light, such as potassium, are called photoemissive. Not all materials are photoemissive, nor are all light sources capable of initiating electron emission from a given substance. For example, in Figure above , we see that 700 nm light will not initiate electron ejection, while 550 nm light will. Q: What are materials that eject electrons when illuminated with light called? Choices: - fragmentation - photogenic - illumination - photoemissive A:
photoemissive

Answer the following question given this paragraph: Cartilaginous Joints Cartilaginous joints are joints in which the bones are connected by cartilage. There are two types of cartilaginous joints: synchondroses and symphyses. In a synchondrosis, the bones are joined by hyaline cartilage. Synchondroses are found in the epiphyseal plates of growing bones in children. In symphyses, hyaline cartilage covers the end of the bone but the connection between bones occurs through fibrocartilage. Symphyses are found at the joints between vertebrae. Either type of cartilaginous joint allows for very little movement. Synovial Joints Synovial joints are the only joints that have a space between the adjoining bones (Figure 38.25). This space is referred to as the synovial (or joint) cavity and is filled with synovial fluid. Synovial fluid lubricates the joint, reducing friction between the bones and allowing for greater movement. The ends of the bones are covered with articular cartilage, a hyaline cartilage,. Q: What term is used to describe joints in which the bones are connected by cartilage? Choices: - capillaries joints - blob joints - spinal joins - cartilaginous joints A:
(Answer)
cartilaginous joints
Ques: Answer the following question given this paragraph: Ferns 11,000 They have large leaves in fronds. They have stiff stems, so they are tall growing; some are trees. They reproduce with spores. They need a moist habitat. Q: What type of habitat do ferns need to grow? Choices: - cold - elevated - dry - moist A:
Ans: moist
(Q).
Answer the following question given this paragraph: the initial momentum of an object. When calculating impulse, consider the change in momentum of one of the objects in the collision. Q: When calculating impulse, consider the change in _______ of one of the objects in the collision? Choices: - sound - potential energy - velocity - momentum A:
(A).
momentum
Ques:Answer the following question given this paragraph: To determine the overall voltage of a particular voltaic cell, simply combine the voltages of the oxidation and reduction half reactions. Even if you need to take a multiple of a half reaction for the electrons to cancel, do not take the multiple of the E1/2. Use the values directly as is from - ball-ch14_s03_t01. Spontaneous redox reactions have positive overall voltages. If the voltage of the reaction as written is negative, it is not spontaneous in that direction. Rather, the reverse reaction is the spontaneous redox reaction. Q: Combining the voltages of the oxidation and reduction half reactions helps to determine what? Choices: - slimy - moisture - magnetic - voltage A:

Ans:voltage
Answer the following question given this paragraph: Sublimation and deposition involve direct transitions between solid and gas without going through the liquid state. Q: Sublimation and deposition involve direct transitions between solid and gas without going through which state? Choices: - chemical - carbon - homeostasis - liquid A:
liquid
