An organ or group of specialized cells in the body that produces and secretes a specific substance, such as a hormone
The process is known as the greenhouse gasses effect
Answer:
Winter,to conserve heat in the body.
Explanation:
The adaptation of the phospholipd bilayer ensures that the phospholipid tails face one another inwards,while the hydrophilic polar head point outwards.These tails can either by saturated or unsaturated. The high the number unsaturated chains the more the fluidity of the cell membrane,This because the un saturated chain are usually bent -kink-and therefore affects the alignments of the chains make them not properly arranged giving room for fluidity(heat).
In addition the longer the length of these chains the higher the fluidity of the membrane.
Note the more saturated the chains ,the more packed the cell membrane the less fluidity and tendency to freeze up.
In cold environment,as the temperature drops,membrane becomes less fluid, bacteria could not control body temperature,and the membrane fluidity drops.To survive these bacteria responds by increasing the number of unsaturated fatty acids chains(desaturated ) to increase the fluidly to keep warm to avoid been frozen up,thus winter is the beneficial
False, A solid will retain its shape; the particles are not free to move around. They are tightly packed together but for a liquid, they are loose and take the shape of the container. Depends on the liquid.
Fatty acids typically contain an even number of carbon atoms because of the way in which fatty acids are biosynthesized. .Unsaturated fatty acids have lower melting points than saturated fatty acids of the same length. Because double bonds cause the hydrocarbon chain to bend.
