Answer the following question given this paragraph: Which layers of the stem are made of parenchyma cells? a. cortex and pith b. phloem c. sclerenchyma d. xylem Like the rest of the plant, the stem has three tissue systems: dermal, vascular, and ground tissue. Each is distinguished by characteristic cell types that perform specific tasks necessary for the plant's growth and survival. Dermal Tissue The dermal tissue of the stem consists primarily of epidermis, a single layer of cells covering and protecting the underlying tissue. Woody plants have a tough, waterproof outer layer of cork cells commonly known as bark, which further protects the plant from damage. Epidermal cells are the most numerous and least differentiated of the cells in the epidermis. The epidermis of a leaf also contains openings known as stomata, through which the exchange of gases takes place (Figure 30.8). Two cells, known as guard cells, surround each leaf stoma, controlling its opening and closing and thus regulating the uptake of carbon dioxide and the release of oxygen and water vapor. Trichomes are hair-like structures on the epidermal surface. They help to reduce transpiration (the loss of water by aboveground plant parts), increase solar reflectance, and store compounds that defend the leaves against predation by herbivores. Q: Which part of a leaf contains openings known as stomata, through which the exchange of gases takes place? A:

OPTIONS:
- stoma
- cuticle
- phloem
- epidermis

Answer: epidermis

Problem: OPTIONS:
- blue giant
- green giant
- white giant
- red giant
Q: Answer the following question given this paragraph: Eventually a main sequence star will use up all of its hydrogen. It then starts to fuse helium atoms into larger elements like carbon. At this time, the star's core will collapse inward. The star's outer layers will spread out and cool. The result is a larger star that is cooler on the surface, and red in color. The star is now a red giant . Q: When a star's core collapses inward while the outer layers spread and cool, what "colorful" celestial body forms? A:
Answer: red giant

Problem:OPTIONS:
- single spiral
- chain helix
- double spiral
- double helix

Answer the following question given this paragraph: Simple Model of DNA. In this simple model of DNA, each line represents a nucleotide chain. The double helix shape forms when the two chains wrap around the same axis. Q: What distinctive dna shape forms when the two nucleotide chains wrap around the same axis? A:
****
A: double helix

Answer the following question given this paragraph: The fatty material inside the artery on the right is plaque. Notice how much narrower the artery has become. Less blood can flow through it than the normal artery. Q: What fatty material inside arteries can restrict blood flow in the artery? A:
OPTIONS:
- marble
- collagen
- cholesterol
- plaque
plaque

Answer the following question given this paragraph: Figure 3.31 A nucleotide is made up of three components: a nitrogenous base, a pentose sugar, and one or more phosphate groups. Carbon residues in the pentose are numbered 1 through 5 (the prime distinguishes these residues from those in the base, which are numbered without using a prime notation). The base is attached to the 1 position of the ribose, and the phosphate is attached to the 5 position. When a polynucleotide is formed, the 5 phosphate of the incoming nucleotide attaches to the 3 hydroxyl group at the end of the growing chain. Two types of pentose are found in nucleotides, deoxyribose (found in DNA) and ribose (found in RNA). Deoxyribose is similar in structure to ribose, but it has an H instead of an OH at the 2 position. Bases can be divided into two categories: purines and pyrimidines. Purines have a double ring structure, and pyrimidines have a single ring. Q: What kind of structure do purines have? A:
OPTIONS:
- triple ring structure
- single ring structure
- helical stucture
- double ring structure

Answer:
double ring structure
