Answer the following question given this paragraph: Natural Methods of Asexual Reproduction Natural methods of asexual reproduction include strategies that plants have developed to self-propagate. Many plantslike ginger, onion, gladioli, and dahliacontinue to grow from buds that are present on the surface of the stem. In some plants, such as the sweet potato, adventitious roots or runners can give rise to new plants Figure 32.25. In Bryophyllum and kalanchoe, the leaves have small buds on their margins. When these are detached from the plant, they grow into independent plants; or, they may start growing into independent plants if the leaf touches the soil. Some plants can be propagated through cuttings alone. Q: Natural methods of asexual reproduction, such as cuttings or budding, include strategies that plants have developed to perform what? A:

OPTIONS:
- multi-propagation
- mono-propagation
- iso-propagation
- self-propagation

Answer: self-propagation

Answer the following question given this paragraph: Summary A suspension is a heterogeneous mixture of particles of one substance distributed throughout a second phase; the dispersed particles separate from the dispersing phase on standing. In contrast, the particles in a colloid are smaller and do not separate on standing. A colloid can be classified as a sol, a dispersion of solid particles in a liquid or solid; a gel, a semisolid sol in which all of the liquid phase has been absorbed by the solid particles; an aerosol, a dispersion of solid or liquid particles in a gas; or an emulsion, a dispersion of one liquid phase in another. A colloid can be distinguished from a true solution by its ability to scatter a beam of light, known as the Tyndall effect. Hydrophilic colloids contain an outer shell of groups that interact favorably with water, whereas hydrophobic colloids have an outer surface with little affinity for water. Emulsions are prepared by dispersing a hydrophobic liquid in water. In the absence of a dispersed hydrophobic liquid phase, solutions of detergents in water form organized spherical aggregates calledmicelles. Phospholipids are a class of detergent-like molecules that have two Saylor URL: http://www. saylor. org/books. Q: A heterogeneous mixture of particles of one substance distributed throughout a second substance in a different phase is known as what? A:

OPTIONS:
- disruption
- solution
- fluid
- suspension

Answer: suspension

Answer the following question given this paragraph: Q: What controls every aspect of plant growth and development to some degree? A:

Answer: hormones

Answer the following question given this paragraph: Blood pressure is read as two numbers. The first number is the systolic pressure. The systolic pressure is the pressure on the blood vessels when the heart beats. This is the time when there is the highest pressure in the arteries. The diastolic pressure, which is the second number, is when your blood pressure is lowest, when the heart is resting between beats. Q: What does the second number in a blood pressure reading measure? A:

OPTIONS:
- external pressure
- optimal pressure
- epithelial pressure
- diastolic pressure

Answer:
diastolic pressure
