Question

Which one of the following is the correct matching of three items and their group category?

• A. Ilium, Ischium, pubis - Coxal bones of pelvic girdle
• B. Actin, myosin, rhodopsin - Muscle proteins
• C. Cytosine, uracil, thiamine - Pyrimidines
• D. Malleus, incus, cochlea - Ear ossicles

Answer 1

The correct option is A Ilium, Ischium, pubis - Coxal bones of pelvic girdle

The pelvic girdle is formed by two innominate bones (hip bones). Each innominate bone consists of three separate bones, ilium ischium, and pubis.
Actin and myosin are muscle proteins but rhodopsin is a biological pigment found in the rods of the retina.
The genetic material in organisms can have 3 pyrimidine bases (thymine, cytosine, and uracil) and 2 purine bases (adenine and guanine). But thiamine, also known as thiamin or vitamin B1, is a vitamin found in food and used as a dietary supplement.
The three auditory ossicles – the malleus, incus, and stapes – are tiny bones found in the middle ear. Cochlea is a part of the inner ear.
