pairs

In the study conducted at Rutgers University, 59 participants performed a memory task that required them to decide whether to pay for feedback while learning word pairs they were later tested on.

This combined data set enabled the team to search for new binaries in clusters with characteristics resembling those of known white dwarf-main sequence pairs.

"After duplication, the majority of genes are still in pairs; however, they show different expression patterns, and many have functionally diverged to regulate different traits," Ma said.

Seabirds can breed in very large colonies, sometimes consisting of several hundred thousand pairs.

Out of the final six to 10 pairs that were made, four pairs worn in the movie are believed to have survived.
