Answer the following question given this paragraph: Unlike amphibians, reptiles do not have a larval stage. Instead, newly hatched reptiles look like smaller versions of the adults. They are able to move about on their own, but they are vulnerable to predators. Even so, most reptile parents provide no care to their hatchlings. In fact, most reptiles don't even take care of their eggs. For example, female sea turtles lay their eggs on a sandy beach and then return to the ocean. The only exceptions are female crocodiles and alligators. They may defend their nest from predators and help the hatchlings reach the water. If the young remain in the area, the mother may continue to protect them for up to a year. Q: Unlike amphibians, reptiles do not have what stage? Choices: - egg - reproductive - adult - larval A:
larval
Answer the following question given this paragraph: Tropical climates are found at or near the Equator. Because warm air rises at the Equator, there is a lot of rain. Q: What kind of climates are found at or near the equator? Choices: - dry grasslands - tundra - arctic climates - tropical climates A:

Q: Answer the following question given this paragraph: The periodic table is one of the cornerstones of chemistry because it organizes all the known elements on the basis of their chemical properties. A modern version is shown in Figure 2.7 "A Modern Periodic Table". Most periodic tables provide additional data (such as atomic mass) in a box that contains each element's symbol. The elements are listed in order of atomic number. Q: The periodic table is one of the cornerstones of chemistry because it organizes all the known elements on the basis of their what? Choices: - size properties - liquid properties - acid properties - chemical properties A:
A: chemical properties
Question: Answer the following question given this paragraph: Nuclear energy is produced by splitting atoms. It also produces radioactive wastes that are very dangerous for many years. Q: What is split to produce nuclear energy? Choices: - molecules - chemicals - protons - atoms A:
Answer: atoms

Answer the following question given this paragraph: After an infection has been brought under control, most cytotoxic T cells die off. However, a few remain as memory cells. If the same pathogen enters the body again, the memory cells mount a rapid immune response. They quickly produce many copies of cytotoxic T cells specific to the antigen of that pathogen. Q: After an infection has been brought under control and most cytotoxic t cells die off, a few remain as what? Choices: - b cells - natural killer cells - control cells - memory cells A:
**Answer**
memory cells

Answer the following question given this paragraph: Fingernails and toenails consist of specialized epidermal cells that are filled with keratin . The keratin makes them tough and hard, which is important for the functions they serve. Fingernails prevent injury by forming protective plates over the ends of the fingers. They also enhance sensation by acting as a counterforce to the sensitive fingertips when objects are handled. Nails are similar to claws in other animals. They cover the tips of fingers and toes. Fingernails and toenails both grow from nail beds. As the nail grows, more cells are added at the nail bed. Older cells get pushed away from the nail bed and the nail grows longer. There are no nerve endings in the nail. Otherwise cutting your nails would hurt a lot!. Q: What fills the epidermal cells that make up fingernails and toenails? Choices: - cellulose - chromatin - amino acids - keratin A:
(Answer)
keratin
