Q: What slow process is required for formation of soil? Read this paragraph and choose the correct option from the provided answers: Soil formation requires weathering. Where there is less weathering, soils are thinner. However, soluble minerals may be present. Where there is intense weathering, soils may be thick. Minerals and nutrients would have been washed out. Soil development takes a very long time. It may take hundreds or even thousands of years to form the fertile upper layer of soil. Soil scientists estimate that in the very best soil forming conditions, soil forms at a rate of about 1mm/year. In poor conditions, it may take thousands of years!. Choices: - leaching - digestion - fossilization - weathering A:
**Answer**
weathering

Q: What is formed when humid air near the ground cools below its dew point? Read this paragraph and choose the correct option from the provided answers: Fog ( Figure below ) is a cloud on the ground. Fog forms when humid air near the ground cools below its dew point. Each type of fog forms in a different way. Choices: - steam - weather - smoke - fog A:
**Answer**
fog

Q: Plasmodesmata and gap junctions are channels between adjacent cells of what respective types? Read this paragraph and choose the correct option from the provided answers: 4.6 Connections between Cells and Cellular Activities Animal cells communicate via their extracellular matrices and are connected to each other via tight junctions, desmosomes, and gap junctions. Plant cells are connected and communicate with each other via plasmodesmata. When protein receptors on the surface of the plasma membrane of an animal cell bind to a substance in the extracellular matrix, a chain of reactions begins that changes activities taking place within the cell. Plasmodesmata are channels between adjacent plant cells, while gap junctions are channels between adjacent animal cells. However, their structures are quite different. A tight junction is a watertight seal between two adjacent cells, while a desmosome acts like a spot weld. Choices: - healthy and sick - new and old - plant and fungus - plant and animal A:
**Answer**
plant and animal

Q: Mass can be destroyed to release what? Read this paragraph and choose the correct option from the provided answers: Mass can be destroyed to release energy. We do not ordinarily notice the increase or decrease in mass of an object because the change in mass is so small for a large increase in energy. The relativistic work-energy theorem is W net = E E 0 = mc 2 mc 2 = 1mc 2 . Relativistically,. Choices: - acceleration - mass - velocity - energy A:
**Answer**
energy
