Answer:
In the lab, I discovered the air pressure, air temperature, and relative humidity conditions that create snow, rain, thunderstorms, fog, and clear skies. I learned that low-pressure areas usually experience snowy, rainy, and stormy weather, and that high-pressure areas usually experience either foggy or sunny weather. Knowing how these atmospheric conditions influence weather help weather forecasters predict weather patterns through maps and other information.
Body organs can be interrelated with other organisms since they are somehow morphologically and physiologically the same.
1. Brain, the brain for most animals are the same, serves the function the same and acts for the many functions of an organism, similarly. This vital organ plays on action-response behavior, management and primal survival instinct, although somehow it's different in structure from the other organisms.
2. Stomach, is an organ wherein the food that is taken in from mouth or opening of a cavity is stored for a short time and is prepared for digestion and metabolic process in the digestive tract or G.I. tract.
I'm not sure if I will answer the question you asked, as I many have interpreted it incorrectly. In natural selection, there must be variance in the gene pool, the total frequency of alleles in a population. Now, one of the organisms may have a gene that somehow helps them survive from the selective force much better compared to the others. If this does happen, over time the gene pool will narrow down to become just the genes of that organism that survived better in the first place because the rest would be taken care of by the selective force. So, the alleles and trait come from the first organisms that had the advantage over the others of its species.
