Question

Pick out the odd one out:
i) globulin, glomerulus, fibrinogen, albumin
ii) mountain goat, big horned sheep, grizzly bear, seal

Answer 1

(i) The globulins are a family of globular proteins that have higher molecular weights than albumins and are insoluble in pure water but dissolve in dilute salt solutions. Fibrinogen (factor I) is a glycoprotein that circulates in the blood of vertebrates. Albumin is a protein made by your liver. Albumin helps keep fluid in your bloodstream so it doesn't leak into other tissues. The glomerulus is a tuft of small blood vessels called capillaries located within Bowman's capsule within the kidney. Globulins, fibrinogen, albumin are all proteins. Hence, glomerulus is the odd one out.
(ii) The mountain goat, also known as the Rocky Mountain goat, is a hoofed mammal endemic to North America. The bighorn sheep is a species of sheep native to North America named for its large horns. The grizzly bear is a large population of the brown bear inhabiting North America. The most widely distributed species of pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic and Pacific Oceans and the Baltic and North Seas.

Mountain goat, bighorn sheep and grizzly bear are found in North America whereas seals are found in northern Atlanta. Hence, the seal is the odd one out.
