Choices: - Tanzanite - Topaz - Amethyst - turquoise A:
(Answer)
turquoise
Ques: Answer the following question given this paragraph: The use of electric current to encode information is called electronics. Electronic signals may be digital or analog signals. Both types of signals encode information by changing the voltage of an electric current, but they do so in different ways. Q: What do we call use of electric current to encode information? Choices: - products - metals - ferious - electronics A:
Ans: electronics
(Q).
Answer the following question given this paragraph: The plot that we know of as a graph was the brainchild of the French mathematician-philosopher Rene Descartes (1596-1650). His studies in mathematics led him to develop what was known as "Cartesian geometry", including the idea of our current graphs. The coordinates are often referred to as Cartesian coordinates. Q: What do we call the mathematical field of study credited to french mathematician-philosopher rene descartes? Choices: - algebra - Euclidean geometry - calculus - cartesian geometry A:
(A).
cartesian geometry
Ques:Answer the following question given this paragraph: Digestion consists of mechanical and chemical digestion. Mechanical digestion occurs in the mouth and stomach. Chemical digestion occurs mainly in the small intestine. The pancreas and liver secrete fluids that aid in digestion. Q: Where does chemical digestion mainly occur? Choices: - apendix - pancreas - liver - small intestine A:

Ans:small intestine
Ques:Answer the following question given this paragraph: CHAPTER SUMMARY 36.1 Sensory Processes A sensory activation occurs when a physical or chemical stimulus is processed into a neural signal (sensory transduction) by a sensory receptor. Perception is an individual interpretation of a sensation and is a brain function. Humans have special senses: olfaction, gustation, equilibrium, and hearing, plus the general senses of somatosensation. Sensory receptors are either specialized cells associated with sensory neurons or the specialized ends of sensory neurons that are a part of the peripheral nervous system, and they are used to receive information about the environment (internal or external). Each sensory receptor is modified for the type of stimulus it detects. For example, neither gustatory receptors nor auditory receptors are sensitive to light. Each sensory receptor is responsive to stimuli within a specific region in space, which is known as that receptor's receptive field. The most fundamental function of a sensory system is the translation of a sensory signal to an electrical signal in the nervous system. All sensory signals, except those from the olfactory system, enter the central nervous system and are routed to the thalamus. When the sensory signal exits the thalamus, it is conducted to the specific area of the cortex dedicated to processing that particular sense. Q: What is a specific region in space within which a sensory receptor is responsive to stimuli? Choices: - deceptive field - amplify field - symmetrical field - receptive field A:

Ans:
receptive field
