Osteoids comprise, significant sections of the entire bone matrix, and this includes fibers of collagen which give bone its flexibility and mechanical strength this allows born to resist stretching and twisting forces.
Osteoblasts are highly specialized cells within bone which formulate new bone through the production or secretion of parts of the organic matrix; this is referred to as the osteoid and mediate the calcification (fortification with allium) of osteoid during the formation of mature bone matrix.

The primary movers are the scalenus.
Answer:
Let the "barred" allele be caller B and the "non-white" allele b. Since chickens use chromosomes
and
to determine sex, hens would have chromosomes
, and roosters would have chromosomes
. A Z-linked gene is represented as a superscript on the
chromosome,
for the dominant allele and
for the ressesive allele.
A barred hen would have a copy of B on its Z chromosome, a non-barred rooster would have both copies of b on both Z chromosomes. Using Punnet squares to represent the crosses we get the following cases:

That is a ratio of two barred heterozygote roosters to two non-barred hens. Crossing them we get:

That is a ratio of one barred heterozygote rooster to one barred hen to one non-barred rooster to one non barred hen.
An aromatic group is a functional group which gives a positive test in a xanthoproteic test.
Xanthoproteic is a test for protein detention. The concentrated nitric acid reacts with proteins if they are present to form yellow colour. By adding alkali it turns orange-yellow through xanthoproteic reaction. Due to a phenyl group, the hydroxyl group can make the test positive in xanthoproteic.
An aromatic group consists of six hydrocarbons with an alternating single and double bond between carbon atoms which form rings.
