Off the top of my head, NTP and DNS lookups for the NTP servers if nothing else.

I don't know what all apt-daily.timer does aside from creating lots of
log msgs, but "daily download activities" doesn't sound like something
I want.  Not that it means all that much, but I haven't noticed any
problems after turning it off:
$ sudo systemctl status apt-daily.timer
● apt-daily.timer - Daily apt download activities
     Loaded: loaded (/lib/systemd/system/apt-daily.timer; disabled;
vendor preset: enabled)
     Active: inactive (dead)
    Trigger: n/a
   Triggers: ● apt-daily.service
