Solutions

1:D - If we’re judging by sheer quantities of fur, the sea otter holds the crown, boasting an astonishing 100,000-160,000 hairs per square centimetre., 2:C - Caterpillars don’t have lungs, but they breathe through tiny openings in their sides called spiracles. Air is forced in and out of the body as they move., 3:B - Bananas are curved because they grow upwards against the force of gravity, aiming towards breaks of light in the rainforest canopy. This process of growing against the direction of gravitational pull is called negative geotropism., 4:B - The vaquita is a porpoise, a small dolphin-like sea mammal found in shallow waters in Mexico’s Gulf of California. They are critically endangered, and experts say that there may be only about 10 of these creatures left. , 5:C - Glands inside the ear canal release a waxy oil called cerumen, which protects the ear from germs and traps dust and dirt. It also helps prevent the ear canal’s delicate skin from being irritated by water.
