Answer the following question given this paragraph: If you're like Tanya in this picture, you prefer your iced tea sweetened with sugar. Sweetened iced tea is a solution in which solid sugar (the solute) is dissolved in cold liquid tea, which is mostly water (the solvent). When you add sugar to tea, particles of water pull apart particles of sugar. The particles of sugar spread throughout the tea, making all of it taste sweet. Q: In a glass of sweet tea the sugar is known as the solute and the water is known as what? Choices: - pigment - solid - calcium - solvent A:
solvent
Answer the following question given this paragraph: An unconformity is a gap in rock layers. They occur where older rock layers eroded away completely before new rock layers were deposited. Q: What is a gap in rock layers called? Choices: - a crevice - a mutation - an anomaly - an unconformity A:
an unconformity
Q: Answer the following question given this paragraph: The measure of how quickly a nucleus decays is given by the half-life of the nucleus. One half-life is the amount of time it will take for half of the radioactive material to decay. Q: What do we call the amount of time it will take for half of the radioactive material to decay? Choices: - one partial-life - one full-life - one quarter-life - one half-life A:
A: one half-life
Question: Answer the following question given this paragraph: Q: What is another name for trisomy 21? Choices: - cystic fibrosis - Tay-Sachs Disease - Fragile X - down syndrome A:
Answer: down syndrome

Answer the following question given this paragraph: Sexual reproduction happens when a sperm and an egg cell combine together. This is called fertilization . Sperm are released into the vagina during sexual intercourse. They "swim" through the uterus and enter a fallopian tube . This is where fertilization normally takes place. Q: What happens when a sperm and an egg cell combine? Choices: - migration - manipulation - stimulation - fertilization A:
**Answer**
fertilization

Answer the following question given this paragraph: Dense Connective Tissue Dense connective tissue contains more collagen fibers than does loose connective tissue. As a consequence, it displays greater resistance to stretching. There are two major categories of dense connective tissue: regular and irregular. Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber orientations. Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers in addition to collagen fibers, which allows the ligament to return to its original length after stretching. The ligaments in the vocal folds and between the vertebrae in the vertebral column are elastic. In dense irregular connective tissue, the direction of fibers is random. This arrangement gives the tissue greater strength in all directions and less strength in one particular direction. In some tissues, fibers crisscross and form a mesh. In other tissues, stretching in several directions is achieved by alternating layers where fibers run in the same orientation in each layer, and it is the layers themselves that are stacked at an angle. The dermis of the skin is an example of dense irregular connective tissue rich in collagen fibers. Dense irregular elastic tissues give arterial walls the strength and the ability to regain original shape after stretching (Figure 4.15). Q: Dense connective tissue contains more collagen fibers than does loose connective tissue. as a consequence, it displays greater resistance to what? Choices: - freezing - contracting - stiffening - stretching A:
(A).
stretching
