The cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and sterols. The amount of each depends upon the type of cell, but in the majority of cases phospholipids are the most abundant, often contributing for over 50% of all lipids in plasma membranes.
the branch of science concerned with the chemical and physicochemical processes and substances that occur within living organisms.
The answer is B, because layers mix better at the poles.
AS PLANTS MAKE FOOD IN PRESENCE OF WATER,CO2,LIGHT AS WELL AS CHLOROPHYLL.
C6H12O6+O2=>CO2+H2O (LIGHT AND CHLOROPHYLL)
ALSO THEY HELP IN THEIR SURVIVAL.
Using energy from light, plants chemically combine carbon dioxide and water to create glucose and oxygen. This process is called photosynthesis. Plants also absorb oxygen gas from the air. Like animals, plants needs oxygen to respire
Answer:
hertz (Hz); decibels (dB)
Explanation:
The Sound Measurement units are: Hertz (Hz) and Decibels (dB).
As you may know, sound travels in waves. The speed of the vibrations of these waves defines the tone of the sound. The tone is measured in Hertz, vibrations per second. The higher the number of vibrations per second the higher the sound. Hertz therefore measures the pitch of the sound. The decibel, in turn, measures the power of the sound, its energy, the stronger or weaker it is emitted. Measures the volume of the sound.
