If double stranded DNA has 14% (guanine), what percent A (adenine), T (thymine) and C (cytosine) would you expect?

If in a double stranded DNA the percentage of guanine is 14%, the percentage of the other bases of the molecule will be 14% for cytosine, 36% for adenine and 36% for thymine.

Explanation:

In the DNA molecule resides all the information of the genome of a living being, according to a specific sequence of nitrogenous bases adenine, guanine, cytosine and thymine. These bases are complemented -purine with pyrimidine- following the rule of base complementarity between one chain and another.

Knowing the percentage that exists of a base, the percentage or proportion of the other nitrogenous bases in a DNA molecule can be determined, approximately, following the rule of Chargaff's base pair.

     Chargaff established in his observations that the DNA of a cell has a purine:pyrimidine ratio of 1:1, so there should be an equivalent amount of guanine for cytosin and a similar amount of thymine for adenine, since they are complementary bases.

According to the law of the base pair, if there is 14% in a DNA strand, there will be a 14% in the molecule:

This rule applies to both chains, since the percentage of bases in a single chain will depend on the specific sequence of bases it has.

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.
