Answer the following question given this paragraph: Transpiration is like evaporation because it changes liquid water to water vapor. In transpiration, plants release water vapor through their leaves ( Figure below ). This water vapor rises into the atmosphere. Q: What is it called when plants release water vapor through their leaves? Choices: - eutrophication - evaporation - photosynthesis - transpiration A:
transpiration

Answer the following question given this paragraph: Tennis is played on a variety of court surfaces: grass, clay, hardcourt, and even carpet. Players know that matches on different surfaces are distinctly different games. The ball bounces differently, and shoes slip on some surfaces but stick on others. These differences are a result of friction. Q: What force explains why a tennis ball bounces differently on different surfaces, and shoes slip on some surfaces but stick on others? Choices: - kinetics - vibration - temperature - friction A:
(Answer)
friction
Ques: Answer the following question given this paragraph: Gluteal Region Muscles That Move the Femur Most muscles that insert on the femur (the thigh bone) and move it, originate on the pelvic girdle. The psoas major and iliacus make up the iliopsoas group. Some of the largest and most powerful muscles in the body are the gluteal muscles or gluteal group. The gluteus maximus is the largest; deep to the gluteus maximus is the gluteus medius, and deep to the gluteus medius is the gluteus minimus, the smallest of the trio (Figure 11.29 and Figure 11.30). Q: Muscles that move what long bone originate on the pelvic girdle? Choices: - patella - tibia - sacrum - femur A:
Ans: femur

Answer the following question given this paragraph: During the early Paleozoic, the amount of carbon dioxide in the atmosphere was much greater than it is today. This may have begun to change later, as land plants became more common. As the roots of land plants began to infiltrate rock and soil began to form, carbon dioxide was drawn out of the atmosphere and became trapped in the rock. This reduced the levels of carbon dioxide and increased the levels of oxygen in the atmosphere, so that by the end of the Paleozoic, atmospheric conditions were similar to those of today. As plants became more common through the latter half of the Paleozoic, microclimates began to emerge and ecosystems began to change. As plants and ecosystems continued to grow and become more complex, vertebrates moved from the water to land. The presence of shoreline vegetation may have contributed to the movement of vertebrates onto land. One hypothesis suggests that the fins of aquatic vertebrates were used to maneuver through this vegetation, providing a precursor to the movement of fins on land and the development of limbs. The late Paleozoic was a time of diversification of vertebrates, as amniotes emerged and became two different lines that gave rise, on one hand, to mammals, and, on the other hand, to reptiles and birds. Many marine vertebrates became extinct near the end of the Devonian period, which ended about 360 million years ago, and both marine and terrestrial vertebrates were decimated by a mass extinction in the early Permian period about 250 million years ago. Q: During the early paleozoic, the amount of carbon dioxide in the atmosphere compared to today was? Choices: - none - the same - much lower - much greater A:
(A).
much greater
Ques:Answer the following question given this paragraph: fossils and birds, specifically in the structure of the hip and wrist bones, as well as the presence of the wishbone, formed by the fusing of the clavicles. One important fossil of an animal intermediate to dinosaurs and birds is Archaeopteryx, which is from the Jurassic period (Figure 29.33). Archaeopteryx is important in establishing the relationship between birds and dinosaurs, because it is an intermediate fossil, meaning it has characteristics of both dinosaurs and birds. Some scientists propose classifying it as a bird, but others prefer to classify it as a dinosaur. The fossilized skeleton of Archaeopteryx looks like that of a dinosaur, and it had teeth whereas birds do not, but it also had feathers modified for flight, a trait associated only with birds among modern animals. Fossils of older feathered dinosaurs exist, but the feathers do not have the characteristics of flight feathers. Q: The fossilized skeleton of archaeopteryx looks like that of a dinosaur, but it had what structures modified for flight, a trait associated only with birds among modern animals? Choices: - fingers - claws - beaks - feathers A:

Ans:feathers
Ques: Answer the following question given this paragraph: The diffusion of water across a membrane because of a difference in concentration is called osmosis . Let's explore three different situations and analyze the flow of water. Q: The diffusion of water across a membrane because of a difference in concentration is called? Choices: - absorption - hemostasis - diffusion - osmosis A:
Ans:
osmosis
