Answer:
The large eyed ducks had an undesirable trait, but the small eyed ducks have a desirable trait. Because the large eyed ducks had a trait that decreases their chances of survival, they wete killed. But small eyed ducks are lucky because they have a trait that increases their chance of survival. The small eyed ducks reproduce more offspring that have small eyes, but the large eyed ducks cannot because they didn't survive. This causes that the allele for large eyes in the gene pool to decrease.
These are the nitrogenous bases in a nucleotide. There are four, which you mentioned in the problem: adenine, thymine, guanine, and cytosine.
The other two parts of a nucleotide make up he backbone: sugar, deoxyribose (DNA=DEOXYRIBOnucleic acid) and the phosphate group.
Hope this helps!!

Answer:
Dimetrodon (/daɪˈmiːtrədɒn/ (About this soundlisten) or /daɪˈmɛtrədɒn/, meaning "two measures of teeth") is an extinct genus of non-mammalian synapsid that lived during the Cisuralian (Early Permian), around 295–272 million years ago (Ma).It is a member of the family Sphenacodontidae. The most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It walked on four legs and had a tall, curved skull with large teeth of different sizes set along the jaws. Most fossils have been found in southwestern United States, the majority coming from a geological deposit called the Red Beds of Texas and Oklahoma. More recently, fossils have been found in Germany. Over a dozen species have been named since the genus was first erected in 1878.
