The amoeba excretes waste through _________ while a sparrow excretes waste through __________.
Answer:
The amoeba excretes waste through Contractile Vacuole while a sparrow excretes waste through Cloaca.
Explanation:
In some unicellular eukaryotic organisms (e.g., amoeba), cellular wastes, such as ammonia and excess water, are excreted by exocytosis as the contractile vacuoles merge with the cell membrane, expelling wastes into the environment.
Birds, unlike mammals, do not have separate exits for urine and feces. Both waste products are eliminated simultaneously through the cloaca. While mammals excrete nitrogenous wastes mostly in the form of urea, birds convert it to uric acid or guanine, which reduces water loss in comparison.
Which water cycle processes usually cause a lowering in the water table? Which processes cause a rise?
Answer:
Explanation:
Lowering: During the summer months, the water table tends to fall, due in part to plants taking up water from the soil surface before it can reach the water table. The water table level is also influenced by human extraction of groundwater using wells; groundwater is pumped out for drinking water and to irrigate farmland.
Rise: Fluctuations in the water table level are caused by changes in precipitation between seasons and years. During late winter and spring, when snow melts and precipitation is high, the water table rises.
The water table typically drops throughout the summer because plants absorb water from the soil's surface before it can get to the water table.
What is Water table?Human groundwater extraction through wells, including pumping out groundwater for drinking water and farmland irrigation, has an impact on the water table level as well.
Variations in precipitation over the course of seasons and years are what create fluctuations in the water table level. The water table rises in the late winter and early spring as snow melts and precipitation levels are high.
The five steps of the nitrogen cycle, which are fixation or volatilization, mineralization, nitrification, immobilization, and denitrification. The fixation process is known as volatilization in this image because soil bacteria convert nitrogen gas (N2) into volatile ammonia (NH3).
Therefore, The water table typically drops throughout the summer because plants absorb water from the soil's surface before it can get to the water table.
