Explanation:
Viruses go around in the air and bacteria you have to touch
Explanation:
A cryosphere is just a hydrosphere but it's frozen in some way. glaciers, ice caps, and icebergs are cryospheres (frozen bodies of water).
Answer:
A. Erosion from wind, water, or ice removes crustal material.
Explanation:
Plain formation can occur in many different ways some plates some planes can form as wind, water and ice erode wear away or remove dirt and rocks on higher land.
Wind picks up and carries along small particles which can be abrasive against surfaces, slowly wearing them away to form more particles. The water and ice transport the fragments of rock and dirt as sediment down hillsides, where it is eventually deposited. This occurs until several layers of sediment are accumulated. Plains can also form at the bases of mountains where water carries a flow of sentiments downhill to flat areas where it further spreads out to deposit the sediment in a fan shape -this is called an alluvial plain.
In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis. Critical in this process is the stoma. Stomata (multiple stoma) are located on the outermost cellular layer of leaves, stems, and other plant parts. An open stoma facilitates the process of photosynthesis in three ways. First, it allows light to enter the intercellular matter and trigger the process. Second, it allows for the uptake of carbon dioxide, a key chemical in producing plant energy. Third, it allows for oxygen to be expelled into the outside environment, a byproduct of photosynthesis that is no longer needed by the cell.
