Ques: Q: What do most organisms eat in the profundal zone of a lake? Read this paragraph and choose the correct option from the provided answers: The deeper water of a lake makes up the profundal zone.

Q: What is prosopagnosia? Read this paragraph and choose the correct option from the provided answers: Brain: Prosopagnosia The failures of sensory perception can be unusual and debilitating. A particular sensory deficit that inhibits an important social function of humans is prosopagnosia, or face blindness. The word comes from the Greek words prosopa, that means "faces," and agnosia, that means "not knowing. " Some people may feel that they cannot recognize people easily by their faces. However, a person with prosopagnosia cannot recognize the most recognizable people in their respective cultures. They would not recognize the face of a celebrity, an important historical figure, or even a family member like their mother. They may not even recognize their own face. Prosopagnosia can be caused by trauma to the brain, or it can be present from birth. The exact cause of proposagnosia and the reason that it happens to some people is unclear. A study of the brains of people born with the deficit found that a specific region of the brain, the anterior fusiform gyrus of the temporal lobe, is often underdeveloped. This region of the brain is concerned with the recognition of visual stimuli and its possible association with memories. Though the evidence is not yet definitive, this region is likely to be where facial recognition occurs. Though this can be a devastating condition, people who suffer from it can get byoften by using other cues to recognize the people they see. Often, the sound of a person's voice, or the presence of unique cues such as distinct facial features (a mole, for example) or hair color can help the sufferer recognize a familiar person. In the video on prosopagnosia provided in this section, a woman is shown having trouble recognizing celebrities, family members, and herself. In some situations, she can use other cues to help her recognize faces. Choices: - way blindness - lack of memory - time blindness - face blindness A:
(A).
face blindness

Ques:Q: Which scientist built the first telescope?

The term "telescope" was coined by the Italian scientist and mathematician Galileo Galilei (15641642). Galileo built the first telescope in 1608. His telescope used two lenses to make distant objects appear both nearer and larger. He subsequently made many improvements to telescope design. Choices: - einstein - newton - darwin - galileo A:

Q: Natural gas, such as those burned by gas stoves, is composed mostly of this? Read this paragraph and choose the correct option from the provided answers: The burner on a gas stove burns with a pretty blue flame like the one pictured in the opening image. The fuel burned by most gas stoves is natural gas, which consists mainly of methane. Methane is a compound that contains only carbon and hydrogen. Like many other compounds that consist of just these two elements, methane is used for fuel because it burns very easily. Methane is an example of a covalent compound. Choices: - sulfur - carbon monoxide - oxygen - methane A:
