Answer:
Two types of orientation behavior are as follows:
Taxis behavior:
This is a type of orientation behavior that mainly occur in response towards the external stimulus. Taxis may be positive (movement towards the stimulus) or negative ( movement away from the stimulus). Different types of taxis behavior are phototaxis, aerotaxis, chemotaxis and magnetotaxis.
Kinesis:
Kinesis may be defined as a type of orientation behavior that can change the complete movement or orientation of the organism. Kinesis is a random movement and organism can move in either direction. Different type of kinesis are klinokinesis and orthokinesis.
Groundwater is enclosed in aquifers. Groundwater
is found within a large range of rocks, but the most effective aquifers
are found in porous, open cavities, and permeable rocks. Aquifers can
contain salty, briny, and fresh water. Groundwater can exit the aquifer
by the pumping of a well, which is usually called discharge. The answer is aquifers.
<span>C.)The average rate at which a mountain range rises each year is used to estimate how long ago the range began to rise.
Since geological time and movement takes place over a huge amount of time, most geologist measure the geological time by taking the average rate of almost all the sample and compare. </span>
