Read this paragraph and choose the correct option from the provided answers: Relief , or terrain, includes all the landforms of a region. A topographic map shows the height, or elevation , of features in an area. This includes mountains, craters, valleys, and rivers. For example, Figure below shows the San Francisco Peaks in northern Arizona. Features on the map include mountains, hills and lava flows. You can recognize these features from the differences in elevation. We will talk about some different landforms in the next section. Choices: - geographic - meteorological - gradient - topographic A:
(Answer)
topographic

Ques: Q: What organism constitutes frothy green "pond scum"? Read this paragraph and choose the correct option from the provided answers: Polluted water can form a frothy green scum on the surface. This "pond scum" is actually a living organism, algae. The algae are plant-like protists.

Q: What happened to earth's species during the permian period? Read this paragraph and choose the correct option from the provided answers: The Permian Period ended with Earth's second mass extinction. During this event, most of Earth's species went extinct. It was the most massive extinction ever recorded. It's not clear why it happened. One possible reason is that a very large meteorite struck Earth. Another possibility is the eruption of enormous volcanoes. Either event could create a huge amount of dust. The dust might block out sunlight for months.

Question: Q: Unlike free-living species of flatworms that are predators or scavengers, what forms feed from the tissues of their hosts? Read this paragraph and choose the correct option from the provided answers: Flatworms The relationships among flatworms, or phylum Platyhelminthes, is being revised and the description here will follow the traditional groupings. Most flatworms are parasitic, including important parasites of humans. Flatworms have three embryonic germ layers that give rise to surfaces covering tissues, internal tissues, and the lining of the digestive system. The epidermal tissue is a single layer of cells or a layer of fused cells covering a layer of circular muscle above a layer of longitudinal muscle. The mesodermal tissues include support cells and secretory cells that secrete mucus and other materials to the surface. The flatworms are acoelomate, so their bodies contain no cavities or spaces between the outer surface and the inner digestive tract. Physiological Processes of Flatworms Free-living species of flatworms are predators or scavengers, whereas parasitic forms feed from the tissues of their hosts. Most flatworms have an incomplete digestive system with an opening, the "mouth," that is also used to expel digestive. Choices: - aquatic - mutualistic - herbiverous - parasitic A:
Answer:
parasitic
