What is the significance of each coastal/shelf zones?

Rocky bottom/ soft bottom intertidal

Estuary

Salt marsh

Mangrove

Coastal zones

Explanation:

Soft bottom intertidal habitats include seabed made up of fine grains of sediments, sand and mud. Depending upon the grain size of the sediment, depth of the seabed, temperature and light exposure, growth of bacteria or microalgae, the biodiversity of these habitats varies. A vast population of burrowing marine organisms like clams, crabs, snails, shrimps, skates, fluke, rays, sea cucumber etc are all found in this habitat. Commercial fishing is a main hazard in this habitat.

An estuary represents an area composed of water and wetland, where a freshwater body (like rivers, stream) meets an ocean. The unique feature of this habitat is the presence of salty brackish water which is a mixture of the salty ocean water and the fresh water.

Salt marsh is a coastal wetland that is mostly flooded and drained by the tidal salt water. The wetland is composed of mud and peat and hence is marshy. Tides often submerge the marshes and hence contain decomposed organic matter.

Mangroves are wetlands found along tropical areas with brackish waters. These help to prevent the ocean coastline. Halophytic plants and trees occupy these areas and form the typical mangrove forests in this habitat. Mangrove trees are unique with its prop root

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.

why many students visually perceive stem as a vapid class?

for many students, however, stem subjects are optically discerned as vapid, tedious, and destitute of authentic-world applications. science and math have always been a major part of the high school curriculum, but many students have disengaged from these subjects because they don’t optically discern that they have any pertinence to the authentic world or students’ daily lives. for them, math and science have become a set of rules, procedures, laws, theorems, and formulas to memorize. some students even develop math apprehensiveness and cerebrate they are incapable of learning higher-level mathematics.

why is stem paramount?

as the u.s. economy changes, the ordinant dictation for stem-capable workers is growing. in may of 2014, the u.s. bureau of labor statistics counted more than 8.3 million stem jobs, which accounted for 6.2 percent of total employment in the cumulated states. that number is expected to perpetuate to increment as u.s. companies grow and innovate to compete in the ecumenical economy. according to the u.s. department of labor, the average salary for all stem jobs is $85,570, which is virtually double the average salary for all jobs.

many people still envision stem professionals as wearing a white lab coat and conducting research in a laboratory. in authenticity, some of the most in-demand stem fields are petroleum engineering, process engineering, and computer engineering. these fields that are experiencing shortages of qualified candidates are additionally among the highest paying, with the average petroleum engineer earning an annual salary of $147,520 in may 2014 according to the u.s. bureau of labor statistics.

in additament, stem subjects edify students valuable skills that are vital for prosperity in all vocations, even those that do not directly require stem erudition. engagement in stem subjects avails students develop quandary-solving, critical mentally conceiving, and leadership skills. these skills are so ecumenical, in fact, that statistics relinquished in the summer of 2013 by the u.s. census bureau designated that about three-quarters of the people with a bachelor’s degree in stem fields are not working in those vocations. many non-stem employers are poaching stem-qualified job candidates because they are more ingenious and collaborative than their non-stem counterparts.

as the ecumenical economy perpetuates to evolve, the desideratum for stem-capable workers will perpetuate to grow. by getting edifiers and students involved in the stem kineticism, an incipient generation of adroit workers will be poised to energize and expand this exhilarating field.
