Answer:
selectively permeable
Cell membranes only allow some molecules through. This characteristic is why cell membranes are selectively permeable. They are not impermeable (not letting anything pass) nor are they freely permeable (letting everything can pass). This quality allows a cell to control what enters and exits it.
Generally, hurricane causes transfer of heat from the ocean to the atmosphere through evaporation. The evaporation of water from the sea surface into the atmosphere is enhanced by hurricane's surface wind, which transport the water vapours to the part of the atmosphere called troposhpere. The wind speed in an hurricane is directly related to the surface pressure of a storm, the stronger the difference in the air pressure in the ocean surface, the higher the wind speed.
They are slightly smaller in size than other grey wolf subspecies and have smaller ears and a shorter nose. The most prominent difference between arctic wolves and other grey wolf subspecies is their all-white coat, which remains white throughout the year. ... Adult Arctic wolves weigh between 75 and 125 pounds
The correct answer is option B, Bio genous Sediment
Reason -
The calcareous ooze is known as biogenous sediment as it has formed from the calcareous microscopic shells of the living organism. These oozes have primarily developed due to the deposition of soft muds in the ocean floor made up of calcium or diatoms or radiolarians.. These biogenous sediments are found in the form of a) mineral calcite and b) aragonite.
Cells require glucose as a source of energy to carry out life processes. Large molecules like glucose cross the cell's plasma membrane by...
Facilitated diffusion through protein channels (Glucose enters a cell by facilitated diffusion through protein channels. Since the molecules are too big to move directly through the semipermeable membrane, there are built-in protein channels to facilitate the movement glucose into the cell. Because the glucose is moving with the concentration gradient, the channel helps the movement; no energy is expended. Active transport requires the use of energy to move molecules or ions against the concentration gradient.
hope this helps!
