Answer the following question given this paragraph: Some arthropods have special excretory structures. They are called coxal glands and Malphigian tubules. Coxal glands collect and concentrate liquid waste from blood. They excrete the waste from the body through a pore. Malphigian tubules carry waste from the digestive tract to the anus. The waste is excreted through the anus. Q: In arthropods, coxal glands and malphigian tubules perform what role? Choices: - ingestion - reproduction - photosynthesis - excretion A:
excretion
Answer the following question given this paragraph: Like boys, girls also go through an adolescent growth spurt . However, girls typically start their growth spurt a year or two earlier than boys (and therefore a couple of centimeters shorter, on average). Girls also have a shorter growth spurt. For example, they typically reach their adult height by about age 15. In addition, girls generally do not grow as fast as boys do during the growth spurt, even at their peak rate of growth. As a result, females are about 10 centimeters (about 4 inches) shorter, on average, than males by the time they reach their final height. Q: Which gender typically experiences growth spurts first? Choices: - no difference - male - transgender - female A:
female
Q: Answer the following question given this paragraph: There are three types of mechanical waves. They differ in how they travel through a medium. The three types are transverse, longitudinal, and surface waves. All three types are described in detail below. Q: How many types of mechanical waves are there? Choices: - five - nine - one - three A:
A: three
Question: Answer the following question given this paragraph: Carbon sequestration captures carbon dioxide as it is emitted by a power plant before it enters the atmosphere. The carbon dioxide is then stored in another form. Carbon is sequestered naturally by forests. Trees take in carbon dioxide for photosynthesis. Artificial methods of sequestering carbon underground are being researched. This is just one of the geoengineering methods that are being researched for reducing carbon dioxide. Q: What captures carbon dioxide as it is emitted by a power plant before it enters the atmosphere? Choices: - chemical sequestration - oxide sequestration - nitrogen sequestration - carbon sequestration A:
Answer: carbon sequestration

Answer the following question given this paragraph: 16.4 The Simple Pendulum A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15. The period of a simple pendulum is. Q: A mass suspended by a wire is a simple type of what and undergoes simple harmonic motion for amplitudes less than about 15 degrees? Choices: - gravity - variation - weight - pendulum A:
**Answer**
pendulum
Q: Answer the following question given this paragraph: The extent to which a substance may be dissolved in water, or any solvent, is quantitatively expressed as its solubility, defined as the maximum concentration of a substance that can be achieved under specified conditions. Substances with relatively large solubilities are said to be soluble. A substance will precipitate when solution conditions are such that its concentration exceeds its solubility. Substances with relatively low solubilities are said to be insoluble, and these are the substances that readily precipitate from solution. More information on these important concepts is provided in the text chapter on solutions. For purposes of predicting the identities of solids formed by precipitation reactions, one may simply refer to patterns of solubility that have been observed for many ionic compounds (Table 4.1). Solubilities of Common Ionic Compounds in Water Soluble compounds contain group 1 metal cations (Li+, Na+, K+, Rb+, and Cs+). Q: The extent to which a substance may be dissolved in water or another solvent is known as what? Choices: - humidity - flexibility - turbidity - solubility A:
A: solubility
