Answer the following question given this paragraph: In some soils, the organic portion is entirely missing. This is true of desert sand. At the other extreme, a soil may be completely organic. Peat, found in a bog or swamp, is totally organic soil. Organic materials are necessary for a soil to be fertile. The organic portion provides the nutrients needed for strong plant growth. Q: Will contour lines ever cross? A:

OPTIONS:
- yes
- in rare cases
- always
- no

Answer: no

Problem: OPTIONS:
- inputs
- tone
- pitch
- loudness
Q: Answer the following question given this paragraph: Loudness refers to how loud or soft a sound seems to a listener. The loudness of sound is determined, in turn, by the intensity of the sound waves. Intensity is a measure of the amount of energy in sound waves. The unit of intensity is the decibel (dB) . Q: What is measured by the intensity of the sound waves? A:
Answer: loudness

Problem:OPTIONS:
- parenchyma cells
- phloem cells
- eukaryotic cells
- animal cells

Answer the following question given this paragraph: 30.1 | The Plant Body By the end of this section, you will be able to: Describe the shoot organ system and the root organ system Distinguish between meristematic tissue and permanent tissue Identify and describe the three regions where plant growth occurs Summarize the roles of dermal tissue, vascular tissue, and ground tissue Compare simple plant tissue with complex plant tissue Like animals, plants contain cells with organelles in which specific metabolic activities take place. Unlike animals, however, plants use energy from sunlight to form sugars during photosynthesis. In addition, plant cells have cell walls, plastids, and a large central vacuole: structures that are not found in animal cells. Each of these cellular structures plays a specific role in plant structure and function. Q: Cell walls, plastids, and a large central vacuole distinguish plant cells from what? A:
****
A: animal cells

Answer the following question given this paragraph: Gastric Secretion The secretion of gastric juice is controlled by both nerves and hormones. Stimuli in the brain, stomach, and small intestine activate or inhibit gastric juice production. This is why the three phases of gastric secretion are called the cephalic, gastric, and intestinal phases (Figure 23.17). However, once gastric secretion begins, all three phases can occur simultaneously. Q: Stimuli in the brain, stomach, and small intestine activate or inhibit production of what secretion? A:
OPTIONS:
- metabolic juice
- sweat
- digestive juice
- gastric juice
gastric juice

Answer the following question given this paragraph: Unlike amphibians, reptiles do not have a larval stage. Instead, newly hatched reptiles look like smaller versions of the adults. They are able to move about on their own, but they are vulnerable to predators. Even so, most reptile parents provide no care to their hatchlings. In fact, most reptiles don't even take care of their eggs. For example, female sea turtles lay their eggs on a sandy beach and then return to the ocean. The only exceptions are female crocodiles and alligators. They may defend their nest from predators and help the hatchlings reach the water. If the young remain in the area, the mother may continue to protect them for up to a year. Q: Unlike amphibians, reptiles do not have what stage? A:
OPTIONS:
- egg
- reproductive
- adult
- larval

Answer: larval

input with options: Answer the following question given this paragraph: The mouth also begins the process of mechanical digestion. Sharp teeth in the front of the mouth cut or tear food when you bite into it (see Figure below ). Broad teeth in the back of the mouth grind food when you chew. Food is easier to chew because it is moistened by saliva from the salivary glands. The tongue helps mix the food with saliva and also helps you swallow. After you swallow, the chewed food passes into the pharynx. Q: Teeth in the back of the mouth are used for what? A:
OPTIONS:
- swallowing food
- tearing food
- cutting food
- grinding food
output:
grinding food
