Q: 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:
A: sunlight
Question: Answer the following question given this paragraph: Children as young as 2 years of age can be vaccinated against viral meningitis. Q: What preventive measure can protect even young children against diseases such as viral meningitis? Choices: - nutrition - surgical intervention - malnutrition - vaccination A:

Answer the following question given this paragraph: Mammals breathe with the help of a diaphragm. This is the large muscle that extends across the bottom of the chest below the lungs. When the diaphragm contracts, it increases the volume of the chest. This decreases pressure on the lungs and allows air to flow in. When the diaphragm relaxes, it decreases the volume of the chest. This increases pressure on the lungs and forces air out. Q: What muscle in the chest helps inflate and deflate the lungs? Choices: - pectoral - cartilage - heart - diaphragm A:
**Answer**
diaphragm
Q: Answer the following question given this paragraph: A circuit that consists of one loop is called a series circuit . You can see a simple series circuit below. If a series circuit is interrupted at any point in its single loop, no current can flow through the circuit and no devices in the circuit will work. In the series circuit below, if one light bulb burns out, the other light bulb won't work because it won't receive any current. Series circuits are commonly used in flashlights. You can see an animation of a series circuit at this URL: http://regentsprep. org/regents/physics/phys03/bsercir/default. htm. Q: What do you call a circuit that consists of one loop, which if interrupted at any point, causes cessation of the whole circuit's electric current? Choices: - parallel circuit - constant circuit - dramatic circuit - series circuit A:
A: series circuit
