Answer:
Phospholipids are amphipathic molecules. This means that they have a hydrophilic, polar phosphate head and two hydrophobic fatty acid tails. These components of the phospholipids cause them to orientate themselves, so the phosphate head can interact with water and the fatty acid tails can't, hence forming a bilayer

Explanation:
1) Reflection is when a ray hits something reflective then bounces back. For example, light reflects off a mirror, which is why you can see yourself in a mirror.
2) Wavelength measures the size of a wave. It is measured from the crest or trough of one wave to the crest or trough of another.
3) Refraction occurs when waves go through different mediums at different speeds. This is why a straw looks bent when in water.
4) Frequency is a way of measuring the speed of a wave. It shows how many waves pass every unit of time.
5) Absorption means that all of the waves were absorbed into the medium and none of them passed through.
Answer and explanation;
-Arctic microbes would have membranes with more unsaturated fatty acids; increasing the unsaturated fatty acid ratio would make it harder for the fatty acids to pack together. This will keep the membrane fluid at lower temperatures, which will benefit organisms that live in very cold climates.
-Microorganisms are adapted for optimum functioning in their normal physiological environments. Any extreme change in environmental conditions from the optimum inflicts a stress on an organism. For this reason they must accommodate a variety of changing conditions and stresses in their environment in order to survive and multiply.
The elbow is less sensitive than the fingertips because it contains less sensory neurons. The more sensory neurons the more signals it sends to your brain which causes sensitivity.
