Earthworms have two muscles which is used in locomotion. Both muscles are circular and longitudinal (inner layer of the series of muscles). The diameter of the earthworms body is reduced when the circular muscles are contracted which makes them appear to be thin. The worm appears short when the longitudinal muscles contract thus, its length is reduced.
Amphioxus on the other hand, have two unique muscle fiber types. This includes deep fibers and smaller but mitochondria-rich superficial fibers. E<span>ach of which has its own innervation.</span>
Answer:
1. D. Evaporation
2. A. A closed lake has no outlet stream.
3. C. The angle of the slope
4. C. Granite
Explanation:
1. The process through which water changes its state from liquid to gaseous is known as evaporation. A source of energy is required for this process to occur, energy that is provided by solar heat in this case. The opposite process in which water changes state from gas to liquid, is known as condensation. Precipitation is the process in which the condensed water reaches the Earth’s surface under the force of gravity. During infiltration, water on the ground surface enters the soil.
2. A closed lake is defined by the lack of any outflow. Thus, any water that does not evaporate, will remain in this type of lake indefinitely.
3. The only criterion not used to describe a mass movement event is the angle of the slope. For such an event, the type of motion is the most important characteristic together with the physical characteristics of the material.
4. Granite is a highly consolidated material and thus it has a very high integrity. The other materials listed have inferior characteristics.
5. Soil erosion is a displacement process that occurs naturally though the action of water and wind. On a steep slope, no soil formation occurs, because, due to gravity, all the eroded material will be transported to another location. Thus, at the slope’s location, no soil formation occurs.
By multiplying the rate constant by the substrate concentration (amount) or by determining reaction velocity (V).
D because they lack roots, stems, and leaves. Nonvascular plants are low-growing, reproduce with spores, and need a moist habitat.
