Which of the following best explains why clear-cutting forests is more destructive than selectively cutting down trees in forests? a. clear-cutting eliminates all trees leaving none behind to maintain soil fertility or house native animals. b. clear-cutting places the land at greater risk for wildfires. c. clear-cutting makes land more attractive for human development. d. clear-cutting causes less soil erosion than selective cutting. select the best answer from the choices provided a b c d

The answer would be A. clear-cutting eliminates all trees leaving none behind to maintain soil fertility or house native animals.

 a. clear-cutting eliminates all trees leaving none behind to maintain soil fertility or house native animals.

Explanation:

The clear-cutting is the process of removing all the trees from the forest or from any other location. The selective cutting is the method of cutting of particular trees from a forest or other locations. Clear cutting is more destructive than selective cutting because of the fact that removal of trees in large number will result in soil erosion. As the trees are responsible for holding the soil by their roots. This will negatively affect the fertility of the soil as the mineral particles necessary for the growth of the plants will be lost by agents like wind and water. Also the trees are the habitat of large diversity of animals like monkeys and squirrels. In clear cutting these animals will loose their habitat they will become susceptible to predators.

c-reactive protein (crp) is an acute phase protein belonging to pentraxin family of proteins, whose levels increases 1000-fold or more in concentration in blood during the occurrence of an injury, inflammation or tissue death.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
