An Aldotetrose is a tetrose sugar (4 Carbons) with an aldehyde functional group on the first atom.
The D- compound contains the last bottom asymmetric -OH group at the right side of the Fischer's projection. The L-compound contains the last bottom asymmetric -OH at the left side of the Fischer projection.
So the Fischer's projection of the four aldotetroses is as follow:

Answer:
the most common injuries from accidents involving dangerous machinery and heavy equipment include: Lacerations. Crushed limbs, hands or fingers. Broken bones.
Group 8 elements are also known as the noble gasses. These elements already have a full valence shell with 8 valence electrons. This leaves the elements non-reactive as they are already stable and in a low energy state.
