Some mutations may be favorable for survival Ex. A genetic mutation can cause animals to be more resistant to illnesses.
Answer:
Roughage is the portion of plant foods, such as whole grains, nuts, seeds, legumes, fruits, and vegetables, that your body can't digest. However, it's an important food source for the beneficial bacteria in your gut. It may also aid weight management and decrease certain risk factors for heart disease.

Just reword this

When fat enters the small intestine, fat digestion occurs. This is where most nutrients are consumed, too. Enzymes that break down fats, carbohydrates, and proteins are formed in your pancreas. The bile that helps you digest fats and certain vitamins is formed by your liver.
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
