Some clover plants produce cyanide to deter herbivores, but the allele for cyanide production makes them more likely to be killed by frost. In warmer southern regions clover populations have a high proportion of cyanide producing alleles, but in colder northern regions, the proportion of cyanide producing alleles is very low. These genetic differences between northern and southern populations is known as:

Suppose your automobile engine produces 1000 units of energy as your drive from point A to point B.  Let’s also suppose that the automobile performs 400 units of work in moving that distance.

As electrons are being moved through the electron transport chain in photosynthesis, where are the protons (H+) being pumped?

Why do passengers in an automobile get whiplash in a sudden stop or rear impact collision?  Why do airbags help to reduce whiplash? Make sure you explain using the Laws/Theories/Principles of Physics.  {For the airbags, there are three different ideas/laws/theories/principles which can apply. You only need to choose one of them.}

When a car goes around a curve, the papers sitting on its dashboard start to move because:
