Do insects have lungs?
Instead of lungs, insects breathe with a network of tiny tubes called tracheae. Air enters the tubes through a row of holes along an insect's abdomen. The air then diffuses down the blind-ended tracheae. Since the biggest bugs have the longest tracheae, they should need the most oxygen to be able to breathe.

When does the brain stop growing?
We used to think that the brain was fully developed by very early teenagerhood and we now realise that the brain doesn't stop developing until mid-20s or even early 30s. There's a lot more information and evidence to suggest that actually brain development in various forms goes on throughout the life span.

Where does duck billed platypus live?
The platypus (Ornithorhynchus anatinus) also known as the duck-billed platypus is a semiaquatic egg-laying mammal endemic to eastern Australia, including Tasmania. Together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth.

How does a giraffe sleep?
In the wild, giraffes almost never lie down because of vulnerability to predators. They usually sleep standing, sometimes sitting, and they give birth standing up. When giraffes sleep, they curl their necks and sleep for about five minutes at a time, sleeping no more than 30 minutes a day.

Who invented the first alphabet?
The original alphabet was developed by a Semitic people living in or near Egypt.* They based it on the idea developed by the Egyptians, but used their own specific symbols. It was quickly adopted by their neighbors and relatives to the east and north, the Canaanites, the Hebrews, and the Phoenicians.

How much water is inside the human body?
By one year of age, that amount drops to about 65%. In adult men, about 60% of their bodies are water. However, fat tissue does not have as much water as lean tissue. In adult women, fat makes up more of the body than men, so they have about 55% of their bodies made of water.
