Sometimes some questions don't have a submit button. This happened to me and I know that you just have to move onto another question. Then when you find one that has an answer button you type in you answer and press the answer button for points.
Answer:
According to wolff (German Anatomist and Surgeon),the adaptation shown by a bone in an healthy animal or human depends on the loads it bear.Therefore, changes in the structure or type load the bone bears, will lead to a corresponding change in the bone bearing the load.A practical example is the development of the bone in hand used by a professional tennis player to hold racket.The bones of this hand usually appear stronger and well developed than the other hand.
When a bony outgrowth, emerges in the mandible close to the surface of the tongue, this outgrowth is called Torus mandibularis. It is commonly found near the premolars, in a bilateral conditions. It is common among the Asian and the indigenous people of Canada, Greenland and Alaska(the Inuit).
If it is caused by bruxism (teeth grinding)This will create stress on the impacted bone.Therefore based on Wolff's theory, the impact of this local stress,(teeth grinding) may cause transformation in the shape of the part of the mandible associated with the teeth,an therefore leads to the bony outgrowth.
This theory may also be interpreted with Lamarck theory of use and disuse.
Let's suppose that "long" is the dominant allele and "oval" is the recessive allele.
let's suppose also that red + white genotype give a pink phenotype
every radish has 2 genotypes for each gene, one from the mother and one from the father
The proportions are: if the radish are homozygotes
red red; long long x white <span>white ;</span> oval oval
red white oval long ; red white oval long ; red white oval long ; red white oval long
We will have 100% of pink - long radish.
A crossmatch from homozygotes species give always a unique phenotype
Zooplankton eat algae. this is an exampke of a feeding stage or trophic level
