Answer the following question given this paragraph: A camp fire is an example of basic thermochemistry. The reaction is initiated by the application of heat from a match. The reaction converting wood to carbon dioxide and water (among other things) continues, releasing heat energy in the process. This heat energy can then be used to cook food, roast marshmallows, or just keep warm when it's cold outside. Q: What kind of energy is released when the thermochemical reaction of a campfire converts wood to carbon dioxide and water? Choices: - ultraviolet - light - smoke - heat A:
heat

Answer the following question given this paragraph: The nitrogen cycle includes air, soil, and living things. Q: The nitrogen cycle includes air, soil, and what? Choices: - water - decomposers - heat - living things A:
(Answer)
living things
Ques: Answer the following question given this paragraph: Work is defined differently in physics than in everyday language. In physics, work means the use of force to move an object. The teens who are playing basketball in the picture above are using force to move their bodies and the basketball, so they are doing work. The teen who is studying isn't moving anything, so she isn't doing work. Not all force that is used to move an object does work. For work to be done, the force must be applied in the same direction that the object moves. If a force is applied in a different direction than the object moves, no work is done. The Figure below illustrates this point. Q: In physics, work means the use of what to move an object? Choices: - mass - energy - leverage - force A:
Ans: force

Answer the following question given this paragraph: Around 1850, a German doctor named Rudolf Virchow was observing living cells under a microscope. As he was watching, one of the cells happened to divide. Figure below shows a cell dividing, like the cell observed by Virchow. This was an "aha" moment for Virchow. He realized that living cells produce new cells by dividing. This was evidence that cells arise from other cells. Q: German doctor rudolf virchow first discovered what process when studying living cells under a microscope? Choices: - radiation - evolution - photosynthesis - cell division A:
(A).
cell division
Ques:Answer the following question given this paragraph: CHAPTER SUMMARY 38.1 Types of Skeletal Systems The three types of skeleton designs are hydrostatic skeletons, exoskeletons, and endoskeletons. A hydrostatic skeleton is formed by a fluid-filled compartment held under hydrostatic pressure; movement is created by the muscles producing pressure on the fluid. An exoskeleton is a hard external skeleton that protects the outer surface of an organism and enables movement through muscles attached on the inside. An endoskeleton is an internal skeleton composed of hard, mineralized tissue that also enables movement by attachment to muscles. The human skeleton is an endoskeleton that is composed of the axial and appendicular skeleton. The axial skeleton is composed of the bones of the skull, ossicles of the ear, hyoid bone, vertebral column, and ribcage. The skull consists of eight cranial bones and 14 facial bones. Six bones make up the ossicles of the middle ear, while the hyoid bone is located in the neck under the mandible. The vertebral column contains 26 bones, and it surrounds and protects the spinal cord. The thoracic cage consists of the sternum, ribs, thoracic vertebrae, and costal cartilages. The appendicular skeleton is made up of the limbs of the upper and lower limbs. The pectoral girdle is composed of the clavicles and the scapulae. The upper limb contains 30 bones in the arm, the forearm, and the hand. The pelvic girdle attaches the lower limbs to the axial skeleton. The lower limb includes the bones of the thigh, the leg, and the foot. Q: Of the three types of skeleton designs - hydrostatic skeletons, exoskeletons, and endoskeletons - which do humans possess? Choices: - none of the above - hydrostatic skeleton - exoskeleton - endoskeleton A:

Ans:endoskeleton
Ques: Answer the following question given this paragraph: When light hits rods and cones, it causes chemical changes. The chemical changes start nerve impulses. The nerve impulses travel to the brain through the optic nerve . Q: Through what does the nerve impulses travel to the brain? Choices: - abducent nerve - trochlear nerve - oculomotor nerve - optic nerve A:
Ans:
optic nerve
