This ring comprises of two tubal tonsils, two palatine tonsils, one adenoid tonsil, and one lingual tonsils. In cases of infection involving the oral mucosa and the pharynx, the tonsils become inflamed as well and the condition is called acute tonsillopharyngitis.

A mutation in which type of cell would only affect the organism and not future generation

Answer:

Somatic cells

A somatic cell mutation in an organism is passed on to the daughter cells in an organism. But this type of mutation doesn't affect the future generations because only genes carried by sperm or ova can become part of offspring's gene material.

What are Genes that produce alternative expressions of a trait called
Brrunno [24]
The answer should be allele(s).

Alleles are alternative forms of genes. For example in eye color, there is brown eye allele that produces brown eyes or blue eye alleles that produces blue eyes. 

However, note that there may be dominant or recessive alleles. Dominant alleles are always expressed, meanwhile, recessive allele is only expressed when there is no dominant allele existing. 

An example is let say brown eye allele is dominant and blue eye allele is recessive. The eye gene is controlled by 2 alleles. If I had one brown eye allele and 1 blue, my eyes will be brown, because brown eye allele is dominant.
