Answer the following question given this paragraph: 18.3 Reconnection and Rates of Speciation Speciation is not a precise division: overlap between closely related species can occur in areas called hybrid zones. Organisms reproduce with other similar organisms. The fitness of these hybrid offspring can affect the evolutionary path of the two species. Scientists propose two models for the rate of speciation: one model illustrates how a species can change slowly over time; the other model demonstrates how change can occur quickly from a parent generation to a new species. Both models continue to follow the patterns of natural selection. Q: What is the name for areas where there is overlap between closely related species? Choices: - mono zones - extinction zones - gap zones - hybrid zones A:
hybrid zones

Answer the following question given this paragraph: 35.5 Growth, morphogenesis, and cell differentiation produce the plant body. Q: Growth, morphogenesis, and cell differentiation produce the plant what? Choices: - fur - fat - tail - body A:
(Answer)
body
Ques: Answer the following question given this paragraph: Eukaryotes have three different versions of the sexual life cycle : a haploid life cycle, a diploid life cycle, and a life cycle known as the alternation of generations ( Figure below ). A life cycle is the span in the life of an organism from one generation to the next. All species that reproduce sexually follow a basic pattern, alternating between haploid and diploid chromosome numbers. The sexual life cycle depends on when meiosis occurs and the type of cell that undergoes meiosis. Q: What is the term for the span in the life of an organism from one generation to the next? Choices: - time consumption - era - life span - life cycle A:
Ans: life cycle
(Q).
Answer the following question given this paragraph: Joints are places where two or more bones of the skeleton meet. With the help of muscles, joints allow the body to move with relatively little force. Some joints can move more than others. Q: Where do two or more bones of the skeleton meet? Choices: - junctures - valves - muscle paths - joints A:
(A).
joints
Ques:Answer the following question given this paragraph: The main functions of polysaccharides are to store energy and form structural tissues. Examples of several other polysaccharides and their roles are listed in the Table below . These complex carbohydrates play important roles in living organisms. Q: The main functions of what complex carbohydrates are to store energy and form structural tissues? Choices: - polypeptides - oligosaccharides - monosaccharides - polysaccharides A:

Ans:polysaccharides
Ques:Answer the following question given this paragraph: Magnesium (Mg) and calcium (Ca) are also important macronutrients. The role of calcium is twofold: to regulate nutrient transport, and to support many enzyme functions. Magnesium is important to the photosynthetic process. These minerals, along with the micronutrients, which are described below, also contribute to the plant's ionic balance. In addition to macronutrients, organisms require various elements in small amounts. These micronutrients, or trace elements, are present in very small quantities. They include boron (B), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), molybdenum (Mo), nickel (Ni), silicon (Si), and sodium (Na). Deficiencies in any of these nutrientsparticularly the macronutrientscan adversely affect plant growth (Figure 31.4. Depending on the specific nutrient, a lack can cause stunted growth, slow growth, or chlorosis (yellowing of the leaves). Extreme deficiencies may result in leaves showing signs of cell death. Q: What process is magnesium important to? Choices: - dna replication - carbon cycle - absorption - photosynthetic A:

Ans:
photosynthetic
