Aglass dish containing a few drops of water in the presence of carbon dioxide gas, nitrogen gas, and small organic compounds is heated by a flame and uv radiation. which early earth scenario does this set-up most closely resemble?

deep sea volcanoes giving off gases, sulfur, and iron to produce organic molecules
lightning in the early atmosphere, which may have produced the first organic molecules
the replication of rna near the ocean's surface in the day and night cycling of temperatures
amino acid formation from organic molecules in ocean water splashing on hot rock, sand, or clay

i think it is letter a

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
