Some people have hitchhiker's thumbs, which bend backwards with a large angle between the two segments (phalanges). The myth is that there are just two kinds of thumbs, straight thumbs (S) and hitchhiker's thumbs (H), and the trait is controlled by a single gene with two alleles, with the allele for S being dominant.This was proposed by Glass and Kistler (1953) and has been the subject of very little research since then.he myth is that there are just two kinds of thumbs, straight thumbs (S) and hitchhiker's thumbs (H), and the trait is controlled by a single gene with two alleles, with the allele for S being dominant.

Two fundamental cellular processes are cellular respiration and photosyn-thesis. Cellular respiration is the process by which cells release stored energy from sugars. Photosynthesis is the process in which producer cells use carbon dioxide, water, and nutrients to produce glucose and oxygen.
answered by Lifeeasy Authors. Photosynthesis is an anabolic process in which the construction of the bio molecules occurs with the expenditure of ATP. Whereas the cellular respiration is a catabolism process in which the breakdown of bio molecules occurs with the release of ATP.That is photosynthesis builds the organic compounds like carbohydrate by combining the carbon dioxide and water.In complementary to the photosynthesis the respiration breaks the carbohydrates into carbon dioxide and water. So both of these processes are regarded as complementary to each other.nswered by Lifeeasy Authors.
