Answer:
Explanation:By getting rid of the deer the tree population increased, the reason behind this is because the deers ate the plants which made less trees
Answer:
D. the need for a surface area of sufficient area to allow the cell's function
Explanation:
Many cellular functions such as the exchange of substances and respiratory gases, absorption of nutrients, cell-cell communication, etc. require the cells to have a sufficient surface area. A small cell has a larger surface area to volume ratio and therefore, maintains a higher rate of exchange of substances. As the cell increases in size, the surface area grows less than its volume. Therefore, the surface area required to perform the cellular functions puts an upper limit on the cell size.
Cells maintain the required surface area by dividing and/or by developing folding or projections on the surface. For instance, the cells in the wall of the small intestine require to maintain a higher surface area for nutrient absorption. Therefore, the cells of the wall of the small intestine develop microvilli to have a larger surface area which in turn supports a relatively higher rate of absorption.
Carbon is removed from the atmosphere cause of plants because of the photosynthetic conversion of carbon dioxide in to carbohydrates.
Carbon enter that atmosphere by respiration of animals, volcanic eruptions, combustion of organic materials, and the decay of plant matter.
Hope this helps :)
