<span>It is a water treatment or water purification with the
use of gravity in order to remove suspended solid from water. Sedimentation is
somewhat like filtering. It filters the solid mass that is in the water to
produce purified water. Sedimentation is usually present in tanks, because a
tank may rust through time, it is the sedimentation process that will filter
those rust to get rid of solid particles in the water. It occurs in different
shapes, there’s the rectangular, circular and triangular shape.</span>
They filter out carbon dioxide, a greenhouse gas, and they produce oxygen as a by-product of photosynthesis. Of course, oxygen is crucial for essential life processes such as cellular respiration.

Answer:
The presence of a larger proportion of unsaturated fatty acids in membranes imparts them fluidity at lower temperatures as required to maintain their normal functioning.
Explanation:
The proportion of unsaturated and saturated fatty acids in membranes regulates their fluidity. At lower temperatures, membranes become more rigid. To maintain their normal fluidity, the proportion of the unsaturated fatty acids in membranes is increased. The unsaturated fatty acids have double bonds in their hydrocarbon tails which in turn do not allow their tight packing and impart fluidity to the membrane core.
At higher temperatures, membranes become more fluid and therefore, the proportion of the unsaturated fatty acids is reduced. The tissues of reindeer at the body's extremities such as those near hooves are exposed to surroundings and thereby, lose heat and have lower temperatures. To maintain the fluidity of membranes, the cells of these tissues incorporate more of the unsaturated fatty acids in their membranes as compared to the tissues in the upper legs where the body temperature is relatively higher.
Answer:
Caves often form by the weathering of rock and often extend deep underground. The word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos, though strictly speaking a cave is exogene, meaning it is deeper than its opening is wide, and a rock shelter is endogene.
