Q: In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is called what? Read this paragraph and choose the correct option from the provided answers: Imagine now that you have a second cup with 100ml of water, and you add 45 grams of table sugar to the water. Just like the first cup, the sugar is the solute, and the water is the solvent. But now you have two mixtures of different solute concentrations. In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic , and the solution with the lower solute concentration is hypotonic . Solutions of equal solute concentration are isotonic . The first sugar solution is hypotonic to the second solution. The second sugar solution is hypertonic to the first. Choices: - acetic - hypothermic - hydrophilic - hypertonic A:
hypertonic

Q: Like the stem, what basic plant structure contains vascular bundles composed of xylem and phloem? Read this paragraph and choose the correct option from the provided answers: Like the stem, the leaf contains vascular bundles composed of xylem and phloem (Figure 30.27). The xylem consists of tracheids and vessels, which transport water and minerals to the leaves. The phloem transports the photosynthetic products from the leaf to the other parts of the plant. A single vascular bundle, no matter how large or small, always contains both xylem and phloem tissues. Choices: - root - flower - bark - leaf A:
leaf
