Answer the following question given this paragraph: Evaporation is a technique used to separate out homogeneous mixtures in which one or more solids are dissolved in a liquid. Typically, the mixture is heated until all of the liquid has vaporized, leaving behind the dissolved solids ( Figure below ). The vapor can also be captured and recondensed into a liquid if desired. Q: What is the term for a technique used to separate out homogeneous mixtures in which one or more solids are dissolved in a liquid? A:
OPTIONS:
- transpiration
- absorption
- distillation
- evaporation
evaporation

Answer the following question given this paragraph: Insecticides are commonly used to control insect pests, but they can have harmful effects on the environment. Q: What are commonly used to control insect pests, but can have harmful effects on the environment? A:
OPTIONS:
- toxins
- fertilizers
- Herbicides
- insecticides

Answer: insecticides

Question: Answer the following question given this paragraph: The metallic bonding model explains the physical properties of metals. Metals conduct electricity and heat very well because of their free-flowing electrons. As electrons enter one end of a piece of metal, an equal number of electrons flow outward from the other end. When light is shone on to the surface of a metal, its electrons absorb small amounts of energy and become excited into one of its many empty orbitals. The electrons immediately fall back down to lower energy levels and emit light. This process is responsible for the high luster of metals. Q: Why does metal conduct heat and electricity so well? A:
OPTIONS:
- electromagnetism
- free flowing photons
- insulation
- free flowing electrons
Answer: free flowing electrons

input with options: Answer the following question given this paragraph: Puberty is the stage of life when a child becomes sexually mature. Puberty begins when the pituitary gland tells the testes to secrete testosterone in boys, and in girls the pituitary gland signals the ovaries to secrete estrogen. Changes that occur during puberty are discussed in the Male Reproductive Development and Female Reproductive Development concepts. Q: What is the name of the stage of life when a child becomes sexually mature? A:
OPTIONS:
- pre-adolescence
- adulthood
- reproductive stage
- puberty
output: puberty

Q: Answer the following question given this paragraph: 17.8 Gonadal and Placental Hormones The male and female reproductive system is regulated by follicle-stimulating hormone (FSH) and luteinizing hormone (LH) produced by the anterior lobe of the pituitary gland in response to gonadotropin-releasing hormone (GnRH) from the hypothalamus. In males, FSH stimulates sperm maturation, which is inhibited by the hormone inhibin. The steroid hormone testosterone, a type of androgen, is released in response to LH and is responsible for the maturation and maintenance of the male reproductive system, as well as the development of male secondary sex characteristics. In females, FSH promotes egg maturation and LH signals the secretion of the female sex hormones, the estrogens and progesterone. Both of these hormones are important in the development and maintenance of the female reproductive system, as well as maintaining pregnancy. The placenta develops during early pregnancy, and secretes several hormones important for maintaining the pregnancy. Q: The male and female reproductive system is regulated by follicle-stimulating hormone (fsh) and luteinizing hormone (lh) produced by what gland? A:

OPTIONS:
- thyroid
- testes
- adrenal
- pituitary

A: pituitary

Answer the following question given this paragraph: Note Today, new elements are usually named after famous scientists. The names of the elements can be cumbersome to write in full, especially when combined to form the names of compounds. Therefore, each element name is abbreviated as a one- or two-letter chemical symbol. By convention, the first letter of a chemical symbol is a capital letter, while the second letter (if there is one) is a lowercase letter. The first letter of the symbol is usually the first letter of the element's name, while the second letter is some other letter from the name. Some elements have symbols that derive from earlier, mostly Latin names, so the symbols may not contain any letters from the English name. Table 2.3 "Element Names and Symbols" lists the names and symbols of some of the most familiar elements. Table 2.3 Element Names and Symbols. Q: Today, new elements are usually named after famous scientists. the names of the elements can be cumbersome to write in full, especially when combined to form the names of compounds. therefore, each element name is abbreviated as a one- or two-letter chemical this? A:
OPTIONS:
- notation
- title
- shorthand
- symbol
