Two membranes contain and protect the inner parts of the chloroplast<span>. They are appropriately named the outer and inner membranes. The inner membrane surrounds the stroma and the grana (stacks of thylakoids). One thylakoid stack is called a granum.</span>
a. the eyewall of a hurricane has a large pressure gradient.
c. wind always moves from a region of lower air pressure to a region of higher air pressure.
d. air pressure always increases with altitude above the surface of earth.
Explanation:
The eye of the storm is often associate with the calmness and is found to have a low-pressure region and has a lower gradient of the pressure system. As the eyes have about pressure 15 times lower than that of the outside storm.
<u>And as it has been observed that in the northern hemisphere the winds often move from the region of the high pressure to the regions of the lower pressure and this pressure increase to the surface of the sea levels and it decreases with the increase in latitude.</u>
Mercury and Venus are the two planets that have no moons. The other planets in the solar system have a combined total of 146 moons, with 27 more potential moons waiting for confirmation.
