2. To determine the advantages of vascular tissue over nonvascular tissue, we need to analyze the given options:

a. Whether organisms have alternation of generations: This characteristic refers to the life cycle of an organism, where it alternates between a haploid (gametophyte) and a diploid (sporophyte) phase. While the presence or absence of alternation of generations may be related to the presence or absence of vascular tissue in some organisms, it does not directly address the advantages of vascular tissue over nonvascular tissue.

b. An organism's size and complexity: This option is more relevant in comparing the advantages of vascular tissue over nonvascular tissue. Vascular tissue allows for the transportation of fluids such as water, nutrients, and sugars throughout the organism, enabling larger and more complex structures to develop. Nonvascular tissue, on the other hand, restricts the size and complexity of the organism due to limitations in nutrient transport.

c. The number of individual offspring produced by each organism: This option is not directly related to the advantages of vascular tissue over nonvascular tissue. It addresses the reproductive capacity of organisms rather than the structural and functional advantages associated with vascular tissue.

Considering the analysis, option d, "all of the above," is incorrect. The correct answer to this question would be option b, "an organism's size and complexity."

3. To determine the characteristics of a typical vascular plant sporophyte, we need to analyze the given options:

a. Includes the developing embryo: This option refers to the embryonic development that occurs within the sporophyte. The sporophyte is the diploid, spore-producing stage of a plant, and it indeed includes the developing embryo.

b. Has roots, shoots, and meristems: This option describes different structures found in vascular plants. Roots are responsible for anchoring the plant and absorbing water and nutrients from the soil. Shoots are above-ground structures involved in photosynthesis and reproduction. Meristems are regions of active cell division where growth occurs. All of these structures are present in a typical vascular plant sporophyte.

c. Has specialized tissues that develop into conducting vessels: This option highlights the presence of specialized tissues in vascular plants that form conducting vessels for the transport of water, nutrients, and sugars. This is a characteristic feature of vascular plants and is indeed present in a typical vascular plant sporophyte.

Considering the analysis, option d, "both b and c," is the correct answer to this question.

5. To determine what is grown on more than 70 percent of the world's cultivated farmland and is rich in specific nutrients, we need to analyze the given options:

a. Fruits; carbohydrates and fiber: While fruits are grown on farmland, they may not necessarily constitute more than 70 percent of cultivated farmland. Additionally, the nutrient content of fruits varies, and while they may contain carbohydrates and fiber, they are not the primary nutrient-rich crop grown on farmland.

b. Roots; starch: While root crops like potatoes are grown on farmland, they also do not constitute the majority of cultivated farmland globally. Additionally, while roots may contain starch, this option does not adequately address the nutrient richness.

c. Grains; carbohydrates and fiber: Grains, such as wheat, rice, and maize, are widely grown on farmland globally, constituting a significant portion of cultivated land. They are rich in carbohydrates and fiber, making this option a plausible answer.

d. Legumes; protein: Legumes, including soybeans, lentils, and chickpeas, are high in protein. However, they do not constitute the primary crop grown on farmland globally.

Considering the analysis, the correct answer to this question would be option c, "grains; carbohydrates and fiber."
