Answer the following question given this paragraph: While the great majority of the alpha particles did pass straight through the foil with no deflection, to everyone's surprise, some alpha particles were deflected. In fact, some alpha were bounced almost straight backward by the foil. Rutherford, using Coulomb's law and Newton's laws found that the results could be explained only if all the positive charge of the atom were concentrated in a tiny, central core, now called the nucleus . Rutherford's model of the atom is therefore, called the nuclear model of the atom. All of the positive charge and essentially all of the mass of the atom are in its nucleus. The atom is 10,000 times as large as the nucleus and is mostly empty space. It was known that electrons are outside the nucleus but how the electrons were arranged in an atom was still a mystery. Q: The nucleus is comprised primarily of? A:
OPTIONS:
- energy
- faith
- matter
- empty space
empty space

Answer the following question given this paragraph: Approximate colors are shown, along with pKin values and the pH range over which the color changes. It is important to be aware that an indicator does not change color abruptly at a particular pH value; instead, it actually undergoes a pH titration just like any other acid or base. As the concentration of HIn decreases and the concentration of In increases, the color of the solution slowly changes from the characteristic color of HIn to that of In. As we will see in Section 16.6 "Buffers", the [In]/[HIn] ratio changes from 0.1 at a pH one unit below pKin to 10 at a pH one unit above pKin. Thus most indicators change color over a pH range of about two pH units. We have stated that a good indicator should have a pKin value that is close to the expected pH at the equivalence point. For a strong acidstrong base titration, the choice of the indicator is not especially critical due to the very large change in pH that occurs around the equivalence point.

OPTIONS:
- phalanges

Answer: plantar

Question: Answer the following question given this paragraph: Starches are complex carbohydrates. They are polymers of glucose. Starches contain hundreds of glucose monomers. Plants make starches to store extra glucose. Consumers can get starches by eating plants. Common sources of starches in the human diet are pictured Figure below . Our digestive system breaks down starches to sugar, which our cells use for energy. Like other animals, we store any extra glucose as the complex carbohydrate called glycogen. Glycogen is also a polymer of glucose. Q: What do plants make to store extra glucose? A:
OPTIONS:
- water
- fats
- sugars
- starches
Answer: starches

OPTIONS:
- bloom
- degradation
- infection
- germination
output: germination

Q: Answer the following question given this paragraph: Scientific notation is a way of writing very large or very small numbers that uses exponents. Numbers are written in the format a 10 b . Q: When does a baby double in length and triple in weight? A:

OPTIONS:
- terrible twos
- fetal stage
- pre-adolescence
- infancy

A: infancy

Answer the following question given this paragraph: 29.6 Mammals Mammals in general are vertebrates that possess hair and mammary glands. The mammalian integument includes various secretory glands, including sebaceous glands, eccrine glands, apocrine glands, and mammary glands. Mammals are synapsids, meaning that they have a single opening in the skull. A key characteristic of synapsids is endothermy rather than the ectothermy seen in other vertebrates. Mammals probably evolved from therapsids in the late Triassic period, as the earliest known mammal fossils are from the early Jurassic period. There are three groups of mammals living today: monotremes, marsupials, and eutherians. Monotremes are unique among mammals as they lay eggs, rather than giving birth to young. Eutherian mammals are sometimes called placental mammals, because all species possess a complex placenta that connects a fetus to the mother, allowing for gas, fluid, and nutrient exchange. Q: What makes monotremes different than other mammals? A:
OPTIONS:
- they lack backbones
- they spawn
- they reproduce asexually
- they lay eggs
they lay eggs
