Crossing over occurs at the four-strand stage when two homologous chromosomes, each consisting of a pair of sister chromatids, are paired. Each crossover involves just two of the four strands and generates two recombinant strands.

Answer:
A tan might indicate sun damage to the skin.
Explanation:
Tanning is the process by which the skin is exposed to the ultraviolet rays that comes from the sun with the purpose of producing a dark-brown coloration called a TAN.
A tan achieved by exposure to the sun can actually indicate that a person's skin is undergoing damage from the UV rays of the sun, hence, the skin responds by producing a protein called melanin, which protects the skin and later forms the dark coloration- tan. From this explanation, tan is got in response to a damaging signal received by the cell, hence, a tan might indicate sun damage to the skin.
Within a phase, a change in heat causes the temperature of the substance to change as the kinetic energy of the molecules changes. During a phase change, however, a change in heat causes a change in the potential energy of the molecules and the temperature will stay the same.
<h3>What is Potential energy?</h3>
Potential energy may be defined as a form of accumulated energy that relies upon the comparative situation of diverse parts of a system.
The above passage determines the differentiation between the kinetic and potential energies with respect to temperature and phase change.
Therefore, it is well described above.
