Answer the following question given this paragraph: The most noticeable magnetic activity of the Sun is the appearance of sunspots. Sunspots are cooler, darker areas on the Sun's surface ( Figure below ). Sunspots occur in an 11 year cycle. The number of sunspots begins at a minimum. The number gradually increases to the maximum. Then the number returns to a minimum again. Q: What is the name for the cooler, darker areas on the sun's surface? Choices: - corona - aurora borealis - anomalies - sunspots A:
sunspots
Answer the following question given this paragraph: Physical science is the study of matter and energy. That covers a lot of territory because matter refers to all the "stuff" that exists in the universe. It includes everything you can see and many things that you cannot see, including the air around you. Energy is also universal. It's what gives matter the ability to move and change. Electricity, heat, and light are some of the forms that energy can take. Q: What branch of science is the study of matter and energy? Choices: - unnatural science - natural science - negative science - physical science A:
physical science
Q: Answer the following question given this paragraph: CHAPTER SUMMARY 30.1 The Plant Body A vascular plant consists of two organ systems: the shoot system and the root system. The shoot system includes the aboveground vegetative portions (stems and leaves) and reproductive parts (flowers and fruits). The root system supports the plant and is usually underground. A plant is composed of two main types of tissue: meristematic tissue and permanent tissue. Meristematic tissue consists of actively dividing cells found in root and shoot tips. As growth occurs, meristematic tissue differentiates into permanent tissue, which is categorized as either simple or complex. Simple tissues are made up of similar cell types; examples include dermal tissue and ground tissue. Dermal tissue provides the outer covering of the plant. Ground tissue is responsible for photosynthesis; it also supports vascular tissue and may store water and sugars. Complex tissues are made up of different cell types. Vascular tissue, for example, is made up of xylem and phloem cells. Q: A plant is composed of two main types of tissue: meristematic tissue and what other kind of tissue? Choices: - synovial tissue - muscle tissue - nonvascular tissue - permanent tissue A:
A: permanent tissue
Question: Answer the following question given this paragraph: Transmutation also occurs when a nucleus undergoes decay. An example of beta decay is the emission of an electron by a carbon-14 nucleus. Q: An example of beta decay is the emission of an electron by a carbon-14 what? Choices: - molecules - ion - protons - nucleus A:
Answer: nucleus

Answer the following question given this paragraph: Plate movements cause continents to drift closer to the poles or the Equator. Ocean currents also shift when continents drift. All these changes can affect Earth's temperature. Q: What causes continents to drift closer to the poles or the equator? Choices: - wind - sediment movements - tidal pull - plate movements A:
**Answer**
plate movements

Answer the following question given this paragraph: The anterior pituitary produces six hormones: growth hormone, prolactin, thyroid-stimulating hormone, adrenocorticotropic hormone, follicle-stimulating hormone, and luteinizing hormone. Growth hormone stimulates cellular activities like protein synthesis that promote growth. Prolactin stimulates the production of milk by the mammary glands. The other hormones produced by the anterior pituitary regulate the production of hormones by other endocrine tissues (Table 16.1). Q: Some hormones produced by the anterior pituitary regulate the production of hormones by other tissues belonging to what system? Choices: - nervous - digestive - cardiovascular - endocrine A:
(A).
endocrine
