No it doesnt have any....
Rafters are usually on 2 ft. centers.
Yes, it does.
From the perspective of a symmetry group, a cube has 48 symmetries total. They include:24 rotational symmetries: the identity6 90° rotations about axes through the centers of opposite faces3 180° rotations about the same axes8 120° rotations about the space diagonals connecting opposite vertices6 180° rotations about axes through the centers of opposite edges24 reflection symmetries that involve one of the above rotations, followed (or, equivalently) preceded by the same reflection
12' is max for a 2 x 4 wall. You will need 69 studs for a 90' wall with 16" centers.

There are 5 chiral carbon atoms in norethynodred.
I think glucose has 4 chiral centres four carbon atoms has four different compound/elements bonded to it.
fifteen.

For a molecule with n chiral centers, there are a possible 2^n isomers that can be formed.
This is my understanding.... though I am no expert by any means... Aldopentoses have 3 chiral centers (assymetrical carbon atoms) which allows for 8 stereoisomers (4D and 4L) while ketopentoses have 2 chiral centers which makes 4 stereoisomers .
For a molecule with n chiral centers, there are a possible 2^n isomers that can be formed.
The 8 isomers of pentose are in the carbohydrate family and are characterized as simple sugars, or monosaccharide's. The asymmetric chiral centers generally refer to the presence of interaction with polarized light.

The number of chiral center of tetracycline is 5 .. there are 5 chiral carbons.If there is confusion about the 25=32 Remark, the previous writer was using the equation- 2 to the power of n= then the number of possible stereoisomers, where n is the number of stereogenic centers, hence 2 to the power of 5 is 32.
