Answer the following question given this paragraph: Organs may be organized into organ systems. An organ system is a group of organs that work together to do the same job. For example, the heart is part of the cardiovascular system. This system also includes blood vessels and blood. The job of the cardiovascular system is to transport substances in blood to and from cells throughout the body. Q: What is a group of organs that work together to do the same job? Choices: - an organ colony - an organ assembly - an organ battery - an organ system A:
an organ system

Answer the following question given this paragraph: An animal-like protist, or a protozoa. These protists have the ability to move, usually with some sort of cilia or flagella, and must obtain their energy from other sources. But obviously, they are much simpler than animals. Q: Cilia or flagella structures give protists what ability? Choices: - reproduction - breathing - eating - movement A:
(Answer)
movement
Ques: Answer the following question given this paragraph: As you would expect, where plates collide there are lots of intense earthquakes and volcanic eruptions. The subducting oceanic plate melts as it reenters the mantle. The magma rises and erupts. This creates a volcanic mountain range near the coast of the continent. This range is called a continental arc . The Andes Mountains, along the western edge of South America, are a volcanic arc ( Figure below ). Q: The subducting oceanic plate does what as it reenters the mantle? Choices: - evaporates - disappers - freezes - melts A:
Ans: melts
(Q).
Answer the following question given this paragraph: Nearly 95% of all earthquakes take place along one of the three types of plate boundaries. As you learned in the Plate Tectonics chapter, scientists use the location of earthquakes to draw plate boundaries. Q: The vast majority of what phenomena occurs along one of three types of plate boundaries? Choices: - tornados - hurricane - volcanoes - earthquake A:
(A).
earthquake
Ques:Answer the following question given this paragraph: 4.2 Epithelial Tissue In epithelial tissue, cells are closely packed with little or no extracellular matrix except for the basal lamina that separates the epithelium from underlying tissue. The main functions of epithelia are protection from the environment, coverage, secretion and excretion, absorption, and filtration. Cells are bound together by tight junctions that form an impermeable barrier. They can also be connected by gap junctions, which allow free exchange of soluble molecules between cells, and anchoring junctions, which attach cell to cell or cell to matrix. The different types of epithelial tissues are characterized by their cellular shapes and arrangements: squamous, cuboidal, or columnar epithelia. Single cell layers form simple epithelia, whereas stacked cells form stratified epithelia. Very few capillaries penetrate these tissues. Glands are secretory tissues and organs that are derived from epithelial tissues. Exocrine glands release their products through ducts. Endocrine glands secrete hormones directly into the interstitial fluid and blood stream. Glands are classified both according to the type of secretion and by their structure. Merocrine glands secrete products as they are synthesized. Apocrine glands release secretions by pinching off the apical portion of the cell, whereas holocrine gland cells store their secretions until they rupture and release their contents. In this case, the cell becomes part of the secretion. Q: The main functions of epithelia are protection from the environment, coverage, secretion and excretion, absorption, and this? Choices: - absorption - accumulation - diffusion - filtration A:

Ans:filtration
Ques: Answer the following question given this paragraph: In this chapter, you saw how pressure and buoyancy of fluids can be used to make work easier from raising a car on a lift to floating a ship on the ocean. Devices that make work easier are called machines in physics. Q: In physics, what do you call devices that make work easier? Choices: - circuits - levers - tools - machines A:
Ans:
machines
