Answer the following question given this paragraph: Angiosperm success is a result of two novel structures that ensure reproductive success: flowers and fruit. Flowers allowed plants to form cooperative evolutionary relationships with animals, in particular insects, to disperse their pollen to female gametophytes in a highly targeted way. Fruit protect the developing embryo and serve as an agent of dispersal. Different structures on fruit reflect the dispersal strategies that help with the spreading of seeds. Q: Angiosperm success is a result of two novel structures that ensure reproductive success: flowers and this? Choices: - food - ants - glass - fruit A:
fruit
Answer the following question given this paragraph: An empirical formula is a formula that shows the elements in a compound in their lowest whole-number ratio. Glucose is an important simple sugar that cells use as their primary source of energy. Its molecular formula is C 6 H 12 O 6 . Since each of the subscripts is divisible by 6, the empirical formula for glucose is CH 2 O. When chemists analyze an unknown compound, often the first step is to determine its empirical formula. There are a great many compounds whose molecular and empirical formulas are the same. If the molecular formula cannot be simplified into a smaller whole-number ratio, as in the case of H 2 O or P 2 O 5 , then the empirical formula is also the molecular formula. Q: What is the term for a formula that shows the elements in a compound in their lowest whole-number ratio? Choices: - measured formula - intrinsic formula - Dwarf Formula - empirical formula A:
empirical formula
Q: Answer the following question given this paragraph: Enzymes are critical to the body's healthy functioning. They assist, for example, with the breakdown of food and its conversion to energy. In fact, most of the chemical reactions in the body are facilitated by enzymes. Q: Most of the chemical reactions in the body are facilitated by what? Choices: - proteins - vitamins - carbohydrates - enzymes A:
A: enzymes
Question: Answer the following question given this paragraph: Found as a pure element in nature; oxides decompose with heating. Q: What causes oxides to decompose? Choices: - humidity - acidity - precipitation - heat A:
Answer: heat

Answer the following question given this paragraph: Abiotic factors are the nonliving parts of ecosystems. They include air, sunlight, soil, water, and minerals. These are all things that are needed for life. They determine which living things and how many of them an ecosystem can support. Figure below shows an ecosystem and its abiotic factors. Q: What is the name for the nonliving parts of ecosystems? Choices: - diverse factors - nucleic factors - Dead factors - abiotic factors A:
**Answer**
abiotic factors

Answer the following question given this paragraph: Like boys, girls also go through an adolescent growth spurt . However, girls typically start their growth spurt a year or two earlier than boys (and therefore a couple of centimeters shorter, on average). Girls also have a shorter growth spurt. For example, they typically reach their adult height by about age 15. In addition, girls generally do not grow as fast as boys do during the growth spurt, even at their peak rate of growth. As a result, females are about 10 centimeters (about 4 inches) shorter, on average, than males by the time they reach their final height. Q: Which gender typically experiences growth spurts first? Choices: - no difference - male - transgender - female A:
**Answer**
female
