Q: Answer the following question given this paragraph: Physical science, in turn, can be divided into chemistry and physics. Chemistry is the study of matter and energy at the scale of atoms and molecules. For example, the synthetic fibers in the swimmer's suit were created in labs by chemists. Physics is the study of matter and energy at all scalesfrom the tiniest particles of matter to the entire universe. Knowledge of several important physics conceptssuch as motion and forcescontributed to the design of the swimmer's suit. Q: The physical sciences can be divided into physics and what other science? A:

OPTIONS:
- biology
- astrology
- phsycology
- chemistry

A: chemistry

input: OPTIONS:
- wavelength
- Ohm
- frequency
- wave amplitude Now, answer this question: Answer the following question given this paragraph: Wave amplitude is determined by the energy of the disturbance that causes the wave. A wave caused by a disturbance with more energy has greater amplitude. Q: What is determined by the energy of the disturbance that causes the wave? A:
A:
output: wave amplitude

Answer the following question given this paragraph: Chemical reactions that consume energy are called endothermic reactions . Energy is usually absorbed from the surroundings as heat. An example is the synthesis of ammonia, described above. In organisms, endothermic reactions are called anabolic reactions . Anabolic reactions construct molecules from smaller units. An example is the synthesis of proteins from amino acids. Endothermic reactions can be represented by the general chemical equation:. Q: Chemical reactions that consume energy are called what? A:

OPTIONS:
- exothermic reactions
- inefficient reactions
- greedy reactions
- endothermic reactions

Answer: endothermic reactions

Problem: OPTIONS:
- solutions
- compounds
- minerals
- products
Q: Answer the following question given this paragraph: Products are substances that are produced in the reaction. Q: Substances produced by a reaction are known as? A:
Answer: products

Problem:OPTIONS:
- assimilation
- fraternization
- purebreed
- hybridization

Answer the following question given this paragraph: Mendel first worked with plants that differed in a single characteristic, such as flower color. A hybridization is a cross between two individuals that have different traits. A hybridization in which only one characteristic is examined is called a monohybrid cross . The offspring of such a cross are called monohybrids. Mendel noted that hybridizing true-breeding (P generation) plants gave rise to an F 1 generation that showed only one trait of a characteristic. For example, a true-breeding purple-flowering plant crossed with a true-breeding white-flowering plant always gave rise to purple-flowered hybrid plants. There were no white-flowered hybrids. Mendel wanted to know what happened to the white-flowers. If indeed a "heritable factor" for white-flower had disappeared, all future offspring of the hybrids would be purple-flowered - none would be white. To test this idea, Mendel let the F 1 generation plants self-pollinate and then planted the resulting seeds. Q: What term is used to describe a cross between two individuals that have different traits? A:
****
A: hybridization

Problem:OPTIONS:
- binary and diploid
- binary and haploid
- diploid and traploid
- haploid and diploid

Answer the following question given this paragraph: CHAPTER SUMMARY 7.1 Sexual Reproduction Nearly all eukaryotes undergo sexual reproduction. The variation introduced into the reproductive cells by meiosis appears to be one of the advantages of sexual reproduction that has made it so successful. Meiosis and fertilization alternate in sexual life cycles. The process of meiosis produces genetically unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell. Fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition. Thus, sexually reproducing organisms alternate between haploid and diploid stages. However, the ways in which reproductive cells are produced and the timing between meiosis and fertilization vary greatly. There are three main categories of life cycles: diploid-dominant, demonstrated by most animals; haploid-dominant, demonstrated by all fungi and some algae; and alternation of generations, demonstrated by plants and some algae. Q: Sexually reproducing organisms alternate between which stages? A:
****
A:
haploid and diploid
