Q: What is root that does not arise from a usual place? Read this paragraph and choose the correct option from the provided answers: the radicle is also growing and producing the primary root. As it grows downward to form the tap root, lateral roots branch off to all sides, producing the typical dicot tap root system. In monocot seeds (Figure 32.21), the testa and tegmen of the seed coat are fused. As the seed germinates, the primary root emerges, protected by the root-tip covering: the coleorhiza. Next, the primary shoot emerges, protected by the coleoptile: the covering of the shoot tip. Upon exposure to light (i. when the plumule has exited the soil and the protective coleoptile is no longer needed), elongation of the coleoptile ceases and the leaves expand and unfold. At the other end of the embryonic axis, the primary root soon dies, while other, adventitious roots (roots that do not arise from the usual place i. the root) emerge from the base of the stem. This gives the monocot a fibrous root system. Choices: - momentous - monomers - hypochlorous - adventitious A:
adventitious

Q: Intensity is defined to be the power per unit area carried by a what? Read this paragraph and choose the correct option from the provided answers: Intensity is defined to be the power per unit area carried by a wave. Power is the rate at which energy is transferred by the wave. In equation form, intensity I is. Choices: - filament - shift - wire - wave A:
wave

Q: Nonvascular plants lack vascular tissue and what? Read this paragraph and choose the correct option from the provided answers: Nonvascular plants lack seeds and vascular tissue. Choices: - cytoplasm - chlorophyll - cells - seeds A:
seeds

Q: All chemical changes involve a transfer of what? Read this paragraph and choose the correct option from the provided answers: All chemical changes involve a transfer of energy. When zinc reacts with hydrochloric acid, the test tube becomes very warm as energy is released during the reaction. Some other reactions absorb energy. While energy changes are a potential sign of a chemical reaction, care must be taken to ensure that a chemical reaction is indeed taking place. Physical changes may also involve a transfer of energy. A solid absorbs energy when it melts, and the condensation of a gas releases energy. The only way to be certain that a chemical reaction has occurred is to test the composition of the substances after the change has taken place to see if they are different from the starting substances. Choices: - heating - fuel - Water - energy A:
energy
