Answer:
Los ácidos grasos saturados carecen de dobles enlaces entre los átomos de carbono individuales, mientras que en los ácidos grasos insaturados hay al menos un doble enlace en la cadena de ácidos grasos. Las grasas saturadas son sólidas a temperatura ambiente, mientras que las grasas insaturadas son líquidas.
Answer:
One involves the movement of the organism, and the other involves a change in the environment.
Explanation:
Most phylogenetically related groups have distribution patterns resulting from dispersion or vicariance. In the first of these processes, the most recent common ancestor of a given group of organisms originally occurred in only one of today's occupied areas, then dispersed to other areas - overcoming pre-existing barriers - in which descendants survived. In the occupied areas, differentiation processes may occur resulting in the formation of new species. In vicariance events, the ancestral population occupied, to some extent, the sum of the areas currently inhabited by their descendants, and was divided into smaller populations by the emergence of barriers that caused isolation between subpopulations. The appearance of the barrier causes the disjunction (separation) observed and corresponds to an event that affects all or most of the biota.
From this we can conclude that the main difference between dispersion and vicariance is that one involves the movement of the organism and the other involves a change in the environment.
