Answer:
1. The one nearest the surface is the "zone of aeration", where gaps between soil are filled with both air and water. Below this layer is the "zone of saturation", where the gaps are filled with water.
2. Larger pores mean less friction between flowing water and the sides of the pores. Smaller pores mean more friction between flowing water and pore walls and more twists and turns for the water to navigate. A permeable material has a greater number of larger, well-connected pore spaces. An impermeable material has fewer, smaller pores that are poorly connected.
3. A cave is any cavity in the ground that is large enough that some portion of it will not receive direct sunlight.
A cavern is a specific type of cave, naturally formed in soluble rock with the ability to grow speleothems.
4. The size of the pores underground rock material has and if the pores are connected
5. Karst regions are formed when there is a chemical reaction between the groundwater and the bedrock. As rain, streams, and rivers flow over the earth's surface, the water mixes with the carbon dioxide that naturally exists in air, and the soil becomes acidic and corrodes the calcium carbonate rock. The carbonate solution seeps into fissures, fractures, crevices, and other depressions in the rock. Sinkholes develop and the fissures and crevices widen and lengthen. As the openings get larger, the amount of water that can enter increases.
Earths moon has a surface gravity equal to one-sixth that or earths surface gravity
Nitrifying bacteria in the soil convert ammonia into nitrite (NO2-) and then into nitrate (NO3-<span>).</span>
Antonie van Leeuwenhoek viewed moving objects from pond water under his microscope and named them “animalcules.
Antonie van Leeuwenhoek was a scientist and the first microscopist to observe protozoa and bacteria. He created microscopes that possess a single high-quality lens of small focal length and isolated tiny animalcules (microbes) from various sources such as pond water, well water and rain water. Through his experiments, he also calculated the sizes of the animalcules.
Answer:
<em>The correct option is D) Ethyl alcohol is produced.</em>
Explanation:
Fermentation can be described as a process by which energy is extracted by organisms such as bacteria and yeast.
Sugars are converted into alcohol by this metabolic process occurring in certain microorganisms. There are two main types of fermentation:
Fermentation which takes place in the presence of oxygen is termed as aerobic fermentation.
The process of fermentation which occurs in the absence of oxygen is termed as anaerobic respiration.
Hence, as alcohol will be produced from both types of fermentation, optic C is correct.
