Answer the following question given this paragraph: Many organisms reproduce sexually. In sexual reproduction, parents of different sexes mate to produce offspring. The offspring have some combination of the traits of the two parents. Ducks are examples of sexually reproducing organisms. Other organisms reproduce asexually. In asexual reproduction, a single parent can produce offspring alone. For example, a bacterial cell reproduces by dividing into two daughter cells. The daughter cells are identical to each other and to the parent cell. Q: In what type of reproduction do parents of different sexes mate to produce offspring? Choices: - subject reproduction - parallel reproduction - dual reproduction - sexual reproduction A:
(Answer)
sexual reproduction

Answer the following question given this paragraph: However, despite this secrecy several contributions were made to modern-day chemistry. Early acids and bases were discovered, and glassware for running chemical reactions was developed. Alchemy helped improve the study of metallurgy and the extraction of metals from ores. More systematic approaches to research were being developed, although the idea of orderly scientific experimentation was not yet well-established. The groundwork was being laid for the development of chemistry as a foundational science. Q: What was the early study of chemistry called? Choices: - magic systems - horticulture - pharmacology - alchemy A:
(Answer)
alchemy

Give an example of a redox reaction that is not a single-displacement reaction. Q: Single-displacement reactions are a subset of what? Choices: - gravitational reactions - kinetic reactions - particle reactions - redox reactions A:
(Answer)
redox reactions
