The littoral zone is also known as the intertidal zone is the place where the land and sea meet and is found between the low and high tide zones. This diverse marine ecosystem is witnessed along the coastlines globally. It comprises ample nutrients and oxygen and is considered home to numerous species.
The littoral zone is further differentiated into vertical zones, like the spray zone and low tide zone. Spray zone also known as the upper littoral, and is dry in the majority of the time, but sprayed with water at the time of high tides. It gets flooded at the time of extreme high tides and storms.
The low tide zone also is known as the lower littoral zone, is generally found under water and gets exposed when the tide becomes abnormally low. The species in this zone are not well used to extreme temperatures and long duration of dryness.
Some of the common organisms found in both spray and low tide zones are isopods and limpets.
<span>There are two
types of modern wind turbines. In a Verical-axis wind turbines (VAWTs), the
shaft is mounted on a vertical axis perpendicular to the ground. They are
aligned with the wind so there’s no adjustment necessary when the wind
direction changes. It can’t start moving on itself that is why it needs a boost
from its electrical system to get started. It uses wires for support so the
rotor elevation is lower. They are less efficient than HAWTs due to its lower
elevation. Lower elevation means slower wind due to ground interferences. The
other type is Horizontal-axis wind turbines (HAWTs), the shaft s mounted
horizontally parallel to the ground. It is constantly aligned with the wind
using a yaw-adjustment mechanism. This mechanism moves the entire rotor left or
right in small increments. It uses a tower to lift the turbine components to an
optimum elevation for wind speed and take up very little ground space. It is
much more efficient than VAWT. The motion that converts into electricity is the
rotor. The answer is letter D.</span>

D

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure.
