Q: Q: Why is the root cap continuously replaced in plants? Read this paragraph and choose the correct option from the provided answers: Root Growth and Anatomy Root growth begins with seed germination. When the plant embryo emerges from the seed, the radicle of the embryo forms the root system. The tip of the root is protected by the root cap, a structure exclusive to roots and unlike any other plant structure. The root cap is continuously replaced because it gets damaged easily as the root pushes through soil. The root tip can be divided into three zones: a zone of cell division, a zone of elongation, and a zone of maturation and differentiation (Figure 30.16). The zone of cell division is closest to the root tip; it is made up of the actively dividing cells of the root meristem. The zone of elongation is where the newly formed cells increase in length, thereby lengthening the root. Beginning at the first root hair is the zone of cell maturation where the root cells begin to differentiate into special cell types. All three zones are in the first centimeter or so of the root tip. Choices: - due to growth - due to pressure - due to rubbing - damage through pushing A:
A: damage through pushing

Q: Q: Vertical layering is an important feature of the terrestrial type of what kind of community? Read this paragraph and choose the correct option from the provided answers: Choices: - habitat - environment - ecosystem - biome A:
A: biome

Q: Q: How quickly a population changes in size over time is known as what? Read this paragraph and choose the correct option from the provided answers: The population growth rate is how quickly a population changes in size over time. The rate of growth of a population may be positive or negative. A positive growth rate means that the population is increasing in size because more people are being added than lost. A negative growth rate means that the population is decreasing in size because more people are being lost than added. Choices: - population impact rate - population multiplication rate - population direction rate - population growth rate A:
A: population growth rate

Q: Q: Carbon dioxide is an example of a material that easily undergoes what? Read this paragraph and choose the correct option from the provided answers: Carbon dioxide is an example of a material that easily undergoes sublimation. Choices: - decomposition - spontaneous mutation - amplification - sublimation A:
A: sublimation
