Bass trombone
A baritone horn looks somewhat like a miniaturized tuba. A bass trombone is still a trombone, but slightly larger. It also has an F trigger, which opens up more tubing near the bell of the trombone and changes the note. This allows players to reach the range from a low E flat to a low B, which is physically impossible on a tenor trombone. Some bass trombones also include another trigger, G flat, which can be opened separately or in combination with the F trigger.
Usually the Trombone, Baritone, Euphonium, Tuba, Bass Clarinet, Baritone Sax all play in bass clef.
I would not consider the regular "tenor trombone" to be a scholarship instrument. However, instruments such as the alto and bass trombone are more likely choices as "scholarship instruments.". If you play tenor now, bass wouldn't be too difficult to learn. Euphonium is an alternative that is more like a tenor trombone.

Trombone. Or, since you specified bass a bass trombone.
A bigger trombone is usually a bass trombone.
Obviously the smaller tenor trombone would have room to spare inside a bass bag.
The bass trombone is typically played in the key of Bb.

No, not a full octave, but it does have a lower range than a tenor trombone.
A tuba.
It is just the same as a regular trombone but with a extra tube which allows the instrument to reach the lower notes. The extra tube is added by means of a rotary valve operated by the player's thumb. A typical bass trombone is a B-flat F trombone. Some older bass trombones were tuned in F or G. These had a long slide which needed a handle to enable the player to fully extend the slide. The G bass trombone was great favourite with the brass bands in England and were still in use well into the 20th century.
