Answer:
When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. It is obviously another source of genetic variation in offspring.

Answer:
Fats and ATP are both energy molecules.
ATP is the source of energy which is directly used by each cell to carry out different functions. All cells use energy in the form of ATP. The mitochondria makes ATP by the process of cellular respiration whenever it is required by the body. ATP is not a stable molecule hence energy cannot be stored in this form.
Fats are long term energy storage molecules. Fats are stable molecules hence they can be used for long term energy storage.
