Answer the following question given this paragraph: Nearly all rocks are made of minerals. A few are made of materials that do not fit the definition of minerals. Q: Nearly all rocks are made of what? Choices: - sand - calcium - magma - minerals A:
minerals
Answer the following question given this paragraph: Many lakes are not natural, but are human-made. People dam a stream in a suitable spot. Water backs up behind the dam, creating a lake. These lakes are "reservoirs" ( Figure below ). Q: A man made lake is known as what? Choices: - Pond - Lake - Lagoon - resevoirs A:
resevoirs
Q: Answer the following question given this paragraph: Q: Which system carries out long-distance transport of materials between the root and shoot systems? Choices: - circulatory tissue system - reproductive tissue system - perceptual tissue system - vascular tissue system A:
A: vascular tissue system
Question: Answer the following question given this paragraph: Pure elements with a high metallic character, meaning those that have chemical properties most similar to properties of metals, are generally very reactive. Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies. Within a compound, metal atoms have a relatively low attraction to shared electrons, as indicated by their low electronegativity values. By following the trend summary in Figure below , you can see that the most reactive metals would reside in the lower left portion of the periodic table. The most reactive metal that occurs naturally in reasonable quantities is cesium, which is always found in nature as a compound, never as a free element. It reacts explosively with water and will ignite spontaneously in air. Francium is below cesium in the alkali metal group, but it is so rare that many of its properties have never even been observed. Q: Exemplified by cesium, which ignites spontaneously in air, pure elements with a high metallic character tend to be very what? Choices: - radiactive - inactive - proactive - reactive A:
Answer: reactive

Answer the following question given this paragraph: CHAPTER SUMMARY 40.1 Overview of the Circulatory System In most animals, the circulatory system is used to transport blood through the body. Some primitive animals use diffusion for the exchange of water, nutrients, and gases. However, complex organisms use the circulatory system to carry gases, nutrients, and waste through the body. Circulatory systems may be open (mixed with the interstitial fluid) or closed (separated from the interstitial fluid). Closed circulatory systems are a characteristic of vertebrates; however, there are significant differences in the structure of the heart and the circulation of blood between the different vertebrate groups due to adaptions during evolution and associated differences in anatomy. Fish have a two-chambered heart with unidirectional circulation. Amphibians have a three-chambered heart, which has some mixing of the blood, and they have double circulation. Most non-avian reptiles have a three-chambered heart, but have little mixing of the blood; they have double circulation. Mammals and birds have a four-chambered heart with no mixing of the blood and double circulation. Q: In most animals, the circulatory system is used to transport blood through the what? Choices: - fur - stratum corneum - nerves - body A:
**Answer**
body

Answer the following question given this paragraph: Nonvascular plants include mosses, liverworts, and hornworts. They are the only plants with a life cycle in which the gametophyte generation is dominant. Figure below shows the life cycle of moss. The familiar, green, photosynthetic moss plants are gametophytes. The sporophyte generation is very small and dependent on the gametophyte plant. Q: Mosses, liverworts, and hornworts are examples of what type of plant in which gametophyte generation is dominant? Choices: - choanocyte plants - vascular plants - photoreactive plants - nonvascular plants A:
(A).
nonvascular plants
