are the new appointments by 45 to various boards effective only during his administration?

6. Pretty standard situation

For example, Obama made over 120 appointments in the final three weeks of his presidency. Obviously, many of those appointments filled vacancies that had existed before they were filled. Indeed, he filled eight of the 12 slots on the Fulbright Scholarship Board in those three weeks, but most of those appointments served only for a year or two before their terms expired and Trump named their replacements. In other instances, Obama appointees resigned before their term expired and Trump's replacement will serve less than full term. For example, Sarah Huckabee Sanders was named to the Fulbright board in October 2019, but her term will expire this coming September and Joe can replace her.

Similarly, Obama filled 17 spots on the Holocaust Museum council between January 1, 2017 and inauguration day, even though only 11 spots expire each year.
