Answer the following question given this paragraph: 36.3 Taste and Smell There are five primary tastes in humans: sweet, sour, bitter, salty, and umami. Each taste has its own receptor type that responds only to that taste. Tastants enter the body and are dissolved in saliva. Taste cells are located within taste buds, which are found on three of the four types of papillae in the mouth. Regarding olfaction, there are many thousands of odorants, but humans detect only about 10,000. Like taste receptors, olfactory receptors are each responsive to only one odorant. Odorants dissolve in nasal mucosa, where they excite their corresponding olfactory sensory cells. When these cells detect an odorant, they send their signals to the main olfactory bulb and then to other locations in the brain, including the olfactory cortex. Q: There are five primary tastes in humans: sweet, sour, bitter, salty, and what? Choices: - hot - aroma - tangy - umami A:
(Answer)
umami
Ques: Answer the following question given this paragraph: A mudslide is the sudden flow of mud down a slope because of gravity. Mudslides occur where the soil is mostly clay. Like landslides, mudslides usually occur when the soil is wet. Wet clay forms very slippery mud that slides easily. You can see an example of a mudslide in Figure below . Q: What do you call the sudden flow of mud down a slope because of gravity? Choices: - rockflow - typhoon - mountainside - mudslide A:
Ans: mudslide
(Q).
Answer the following question given this paragraph: Optical telescopes are designed to collect visible light. The two types of optical telescopes are reflecting telescopes and refracting telescopes. Q: What are the two types of optical telescopes? Choices: - reflecting and recapitulating - reflecting and layering - refracting and compound - reflecting and refracting A:
(A).
reflecting and refracting
Ques:Answer the following question given this paragraph: Nephrons filter about cup of body fluid per minute. In a 24-hour period, nephrons filter 180 liters of fluid, and 1.5 liters of the fluid is released as urine. Urine enters the bladder through the ureters. Similar to a balloon, the walls of the bladder are stretchy. The stretchy walls allow the bladder to hold a large amount of urine. The bladder can hold about 1 to 2 cups of urine but may also hold more if the urine cannot be released immediately. Q: Through what does urine enter the bladder? Choices: - the enterocytes - the vas deferens - the tubules - the ureters A:

Ans:the ureters
Ques: Answer the following question given this paragraph: Solution 1. Saltwater acts as if it were a single substance even though it contains two substancessalt and water. Saltwater is a homogeneous mixture, or a solution. Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture. Water is a substance; more specifically, because water is composed of hydrogen and oxygen, it is a compound. Oxygen, a substance, is an element. Q: Saltwater is a homogeneous mixture, another term for what? Choices: - structure - element - lipid - solution A:
Ans:
solution
