Fingerprints are the traces of an impression from epidermal ridges on the fingers of humans. When fingertips brush across an uneven surface these ridges help us better perceive texture, and they also assist in gripping wet surfaces. Many animals lack fingerprints (cats and dogs do NOT have fingerprints). They occur occasionally in other animals whose lifestyle involves climbing or grasping wet objects, but these are usually unique prints that do not look like human fingerprints. Interestingly the Australian koalas (marsupials) have fingerprints that are very similar in their microscopic morphology, organization into patterns and pattern uniqueness to an individual, to those of humans. The presence of fingerprints in humans and Koalas is an example of:

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
