Answer the following question given this paragraph: Primates usually rely more on the sense of vision rather than the sense of smell, which is the dominant sense in many other mammals. The importance of vision in primates is reflected by the bony socket that surrounds and protects the primate eye. Primates have widely spaced eyes in the same plane that give them stereoscopic (3-D) vision, needed for judging distances. Some primates, including humans, have also evolved color vision. Q: The anatomy of primate eyes shows they tend to rely more on vision than what sense, which is dominant in many other mammals? Choices: - taste - touch - hearing - smell A:
smell

Answer the following question given this paragraph: Plant Responses to Gravity Whether or not they germinate in the light or in total darkness, shoots usually sprout up from the ground, and roots grow downward into the ground. A plant laid on its side in the dark will send shoots upward when given enough time. Gravitropism ensures that roots grow into the soil and that shoots grow toward sunlight. Growth of the shoot apical tip upward is called negative gravitropism, whereas growth of the roots downward is called positive gravitropism. Amyloplasts (also known as statoliths) are specialized plastids that contain starch granules and settle downward in response to gravity. Amyloplasts are found in shoots and in specialized cells of the root cap. When a plant is tilted, the statoliths drop to the new bottom cell wall. A few hours later, the shoot or root will show growth in the new vertical direction. The mechanism that mediates gravitropism is reasonably well understood. When amyloplasts settle to the bottom of the gravity-sensing cells in the root or shoot, they physically contact the endoplasmic reticulum (ER), causing the release of calcium ions from inside the ER. This calcium signaling in the cells causes polar transport of the plant hormone IAA to. Q: Gravitropism ensures that roots grow into the soil and that shoots grow toward what? Choices: - the north pole - trees - the south pole - sunlight A:
(Answer)
sunlight
Ques: Answer the following question given this paragraph: The strength of bases is measured on a scale called the pH scale, which ranges from 0 to 14. On this scale, a pH value of 7 indicates a neutral solution, and a pH value greater than 7 indicates a basic solution. The higher the pH value is, the stronger the base. The strongest bases, such as drain cleaner, have a pH value close to 14. Q: The strength of bases is measured on what scale? Choices: - acid test - litmus test - pneumatic scale - ph scale A:
Ans: ph scale

Answer the following question given this paragraph: Refraction The changing of a light ray's direction (loosely called bending) when it passes through variations in matter is called refraction. Speed of Light The speed of light c not only affects refraction, it is one of the central concepts of Einstein's theory of relativity. As the accuracy of the measurements of the speed of light were improved, c was found not to depend on the velocity of the source or the observer. However, the speed of light does vary in a precise manner with the material it traverses. These facts have far-reaching implications, as we will see in Special Relativity. It makes connections between space and time and alters our expectations that all observers measure the same time for the same event, for example. The speed of light is so important that its value in a vacuum is one of the most fundamental constants in nature as well as being one of the four fundamental SI units. Q: The changing of a light ray's direction (loosely called bending) when it passes through variations in matter is called this? Choices: - wavelength - resonance - vibration - refraction A:
(A).
refraction
Ques:Answer the following question given this paragraph: Freshwater below Earth's surface is called groundwater . The water infiltrates, or seeps down into, the ground from the surface. How does this happen? And where does the water go?. Q: What is freshwater below the earth's surface called? Choices: - geyser - sediment - precipitation - groundwater A:

Ans:groundwater
Answer the following question given this paragraph: Birds have light-weight bones that are filled with air. They also lack a jaw, which in many vertebrates is a dense, heavy bone with many teeth. Instead, birds have a light-weight keratin beak without teeth. Q: Birds have light-weight bones that are filled with what? Choices: - water - proteins - blood - air A:
air
