Answer: Rheumatoid arthritis
Explanation:
Rheumatoid arthritis is a disease which is a autoimmune disease which is usually associated with the pain and inflammation in the joints. This is the condition in which the person is not able to walk or sit for a longer period of time as it is painful.
The lysosomes is an enzyme that is found in the saliva and tears of human beings which helps in the degradation of the cell wall.
In case of autoimmune diseases the antibody present in the body destroys the cells of the body considering it as self antigen. Its concentration is found high in the people suffering from this autoimmune disorder.

(idk about the significant figures, SORRY)
Answer:
(i) An allele is a variant of a gene, can either be short or tall.
Dominant = the tall allele that "trumps" the short allele. if a dominant and recessive allele is present (heterozygous) then the dominant phenotype will be shown.
(ii) David's eyes are Brown
(iii) Sarah's eyes are blue
(iv) David - B, b
Sarah - b, b
(v) Possible genotypes include Bb and bb. These give the phenotypes of brown eyes or blue eyes.
(vi) The chance for blue eyes is 50% (or 1:1 ratio)
A dominant allele can produce a dominant phenotype in individuals with one copy of the allele from one or both parents, but a for recessive allele to produce a recessive phenotype, the individual needs to have two copies, one from each parent.
