Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain. Saturated fats tend to be solid at room temperature and from animal sources, while unsaturated fats are usually liquid and from plant sources :)
Answer:
C
Explanation:
An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or a physical process, such as the melting of ice cubes.
1) a series of circulation cells for the tropics, (2) a series for the polar regions and (3) a very dynamic series of cells in the midlatitudes
1. The population is under selection pressure from predators
<span>2. Hey now, no population is ever at H-W equilibrium: </span>
<span>mutations happen </span>
<span>immigration and emigration can occur </span>
<span>the population is not huge, which means that genetic drift can happen </span>
<span>mating is not completely random -- a rat is more likely to mate with someone local than with someone living in Paris, France. </span>
<span>b) The small rats will be selected for (assuming there are predators in this ecosystem that are less likely to look in bushes, and further assuming that the small rats do not have reduced fertility by dint of being small) </span>
<span>This is "directional selection" </span>
<span>c) I would expect the "smallness" allele frequency to increase in this population over time, and the "normal size" allele frequency to decrease.</span>
