1) Birds don’t urinate -TRUE
Birds do not have a urinary bladder like most mammals. Instead, their kidneys efficiently extract waste products, including uric acid, from their bloodstream.
The uric acid combines with feces in the bird’s digestive system and is eliminated together as a pasty substance called “urine.”
2) Horses and cows sleep while standing up -TRUE
Horses and cows have a unique ability to sleep while standing up. They possess a specialized stay apparatus in their legs, which allows them to lock their joints to avoid collapsing while asleep. In this way, they can rest and sleep in a standing position.
However, horses and cows do lie down occasionally for deep sleep.
3) The bat is the only mammal that can fly. The leg bones of a bat are so thin that no bat can walk. -TRUE
Bats are the only mammals capable of sustained flight. Their wings are modified forelimbs with elongated fingers covered by a thin membrane of skin. Due to the adaptations for flight, bat leg bones are relatively thin and not suited for walking or running like other mammals.
Although bats can move awkwardly on the ground, their primary mode of transport is through flying.
4) Even when a snake has its eyes closed, it can still see through its eyelids. -FALSE
Snakes do not possess movable eyelids, and their eyes are always open. However, they do have a specialized transparent scale called the “spectacle” covering their eyes.
This spectacle protects their eyes while allowing them to see their surroundings. So, while snakes cannot close their eyes, they can still see even when their eyes are covered by the spectacle.
5) Despite the white, fluffy appearance of the Polar Bear’s fur, it has black skin. -TRUE
The Polar Bear’s fur appears white due to its translucent hollow hairs that reflect light. However, beneath their fur, Polar Bears have black skin. The black skin helps them absorb and retain heat from the sun, which is crucial for survival in their cold Arctic habitat.
The dark color allows them to maximize heat absorption and insulate their bodies in extremely cold conditions.
6) The average housefly has a relatively short lifespan of around 2 to 3 weeks. -True.
7) While it is difficult to determine the exact number, it is not accurate to claim that for every human in the world, there are one million ants. The ant population is estimated to be in the billions or even trillions, far outnumbering humans. -False.
8) Placing a small amount of alcohol on a scorpion will not make it go crazy and sting itself to death. This is a myth with no scientific evidence to support it. –False.
9) Alligators and some shark species have the potential to live up to 100 years, though it varies depending on the species and other factors. –True.
10) Honeybees indeed have two stomachs, one for storing and transporting nectar (which is later transformed into honey) and another for digesting food. –True.

11) The tongue of a blue whale weighs significantly less than an elephant. However, the heart of a blue whale is indeed quite large, roughly the size of a small car. –False.
12) Blue whales are indeed the largest creatures to have ever roamed the Earth. As for their reproductive organs, they possess a penis that can range from 2.5 meters to 3 meters in length and a diameter of 30 centimeters to 36 centimeters. Their testes are also remarkably large, weighing up to 150 pounds each and capable of ejaculating gallons of sperm. –True.
13) Cockroaches can survive for approximately a week without their heads due to their decentralized nervous system. However, they ultimately die from dehydration or starvation, as they require their mouths to eat and drink. –True.
14) Dolphins are known to exhibit cooperative behavior. When a sick or injured dolphin cries out in distress, other dolphins often come to its aid, helping support it to the surface so it can breathe. –True.
15) While snails are capable of entering a dormant state called estivation for extended periods, they do not sleep for 3 years continuously. –False.
16) The spine-tailed swift is recognized as one of the fastest bird species, capable of reaching speeds up to 106 mph during its swift flight. However, it should be noted that the peregrine falcon holds the record for the fastest level flight speed, reaching up to 390 km/hr or 108 mph. –True.
17) A cow does not give nearly 200,000 glasses of milk in her lifetime. The actual amount of milk produced by a cow will vary depending on factors such as breed, individual health, and lactation duration. –False.
18) The claim that a leech has 32 brains is not true. Leeches have a relatively simple nervous system with a collection of ganglia, also known as a nerve mass, but not multiple brains. –False.
19) The average lifespan of an outdoor-only cat tends to be shorter, around three years due to various risks and hazards they encounter. On the other hand, indoor-only cats can live for sixteen years or even longer, benefiting from a safer and protected environment. –True.
20) While it is true that sharks have a remarkable immune system and are generally resistant to diseases, it is incorrect to claim that they are entirely immune to every type of disease, including cancer. Sharks can indeed get sick, although their immune system defenses make them less susceptible to certain illnesses compared to other animals. –False.
21) A mosquito’s proboscis does not possess 47 sharp edges on its tip. The proboscis is a long, slender mouthpart that aids the mosquito in piercing the skin of its host and extracting blood. Although it is designed to be sharp, it typically does not have anywhere near 47 distinct edges. –False.
22) The statement that the human brain has memory space of over 2.5 Million Petabytes, which is 2,500,500 Gigabytes, is not accurate. While the human brain is a complex organ capable of storing vast amounts of information, providing precise measurements of its memory capacity in terms of Petabytes or Gigabytes is speculative.
The brain’s storage capacity is difficult to quantify in a standard digital storage unit. –False.
