Answer the following question given this paragraph: Matter is all the "stuff" that exists in the universe. Everything you can see and touch is made of matter, including you! The only things that aren't matter are forms of energy, such as light and sound. In science, matter is defined as anything that has mass and volume. Mass and volume measure different aspects of matter. Q: In science, anything that has mass and volume is considered what? Choices: - renewable - visible - an element - matter A:
matter
Answer the following question given this paragraph: View this animation (http://openstaxcollege. org/l/ headblow) to see how a blow to the head may produce a contrecoup (counterblow) fracture of the basilar portion of the occipital bone on the base of the skull. Why may a basilar fracture be life threatening? 3. Osteoporosis is a common age-related bone disease in which bone density and strength is decreased. Watch this video (http://openstaxcollege. org/l/osteoporosis) to get a better understanding of how thoracic vertebrae may become weakened and may fractured due to this disease. How may vertebral osteoporosis contribute to kyphosis? 4. Watch this animation (http://openstaxcollege. org/l/ diskslip) to see what it means to "slip" a disk. Watch this second animation (http://openstaxcollege. org/l/ herndisc) to see one possible treatment for a herniated disc,. Q: What is a common age-related bone disease in which bone density and strength is decreased? Choices: - fibrosis - lupus - arthritis - osteoporosis A:
osteoporosis
Q: Answer the following question given this paragraph: Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion, osmosis, and facilitated diffusion. Q: In passive transport, small molecules or ions move across the cell membrane without requiring input of what? Choices: - pressure - water - heating - energy A:
A: energy
Question: Answer the following question given this paragraph: The pioneer species is soon replaced by other populations. Abiotic factors such as soil quality, water, and climate will determine the species that continue the process of succession. Mosses and grasses will be able to grow in the newly created soil. During early succession, plant species like grasses that grow and reproduce quickly will take over the landscape. Over time, these plants improve the soil and a few shrubs can begin to grow. Slowly, the shrubs are replaced by small trees. Small trees then are succeeded by larger trees. Since trees are more successful at competing for resources than shrubs and grasses, a forest may be the end result of primary succession. Q: What's the term for the gradual progression from simple plants to larger more complex ones in an area? Choices: - complex progression - pattern progression - primary pattern - primary succession A:
Answer: primary succession

Answer the following question given this paragraph: A white dwarf is a stellar remnant that is very dense. A white dwarf's mass is comparable to the Sun and its volume is comparable to that of Earth. The very low brightness of a white dwarf comes from the emission of stored heat energy. Q: What is a stellar remnant that is very dense? Choices: - asteroids - the sun - white star - white dwarf A:
**Answer**
white dwarf
(Q).
Answer the following question given this paragraph: Even though they are very strong, bones can fracture , or break. Fractures can happen at different places on a bone. They are usually caused by excess bending stress on the bone. Bending stress is what causes a pencil to break if you bend it too far. Q: What usually causes fractures on a bone? Choices: - compressive stress - shear stress - extra weight - excessive bending stress A:
(A).
excessive bending stress
