Diversity in Living Organisms

The King Cobra is the only known snake species that builds a nest for its eggs - the female constructs elaborate leaf piles and guards them until hatching. Many snakes can swim, not just King Cobras. King Cobra incubation is around 60-90 days, not over 100 days. They are native to Southeast Asia, not found worldwide.

King Cobras can raise approximately one-third of their body length off the ground when in their threatening display posture. This allows them to target prey or threats at face/neck level. Raising half or more of their body would be physically unstable and is not consistent with observed cobra behavior.

Eskimos (Inuit) live in the Arctic region around the North Pole. Penguins are native to Antarctica and the Southern Hemisphere. They naturally never encounter each other.

Cheetahs overheat rapidly during high-speed sprints because their metabolic rate increases dramatically, generating excessive body heat. Unlike other cats, they cannot sweat effectively to cool down, and prolonged sprinting can cause brain damage or death from hyperthermia. This limits their hunting technique to short, intense bursts followed by recovery periods. Their diet of meat actually provides excellent physical fitness, contradicting option A.

Siphonophores, particularly species like the giant siphonophore (Praya dubia), can grow up to 40-50 meters in length, making them the longest animals in the world. While lion's mane jellyfish are often cited as the longest, siphonophores are colonial organisms that can extend even longer. A siphonophore discovered in 2020 was measured at approximately 46 meters, confirming their status as the longest animals.

Chocolate contains theobromine, which dogs cannot metabolize effectively. It affects their heart and nervous system, causing vomiting, seizures, and potentially death. The toxicity depends on the chocolate type and dog size - dark chocolate is most dangerous, and even small amounts can kill small dogs.

Birds lack sweat glands, so they rely on alternative cooling methods like panting (evaporative water loss from respiratory tract) and seeking shade. They regulate body temperature through blood flow adjustments to unfeathered areas like legs. This anatomical constraint shapes their thermoregulatory behavior.

The zoological name for frog is Rana tigrina (now often classified as Hoplobatrachus tigerinus). 'Tarantuila' is a spider reference, 'Pisum sativum' is a pea (botany), and 'Elephus indicus' appears to be a garbled reference to elephants (Elephas maximus indicus).

The answer is correct based on geographic reality. Eskimos (Inuit people) live in the Arctic region near the North Pole, while penguins are native to the Southern Hemisphere and Antarctica (South Pole). There are no penguins in the Arctic region naturally.

Giraffes have equal-length legs. Their distinctive sloping back is due to the neck structure and spinal alignment, not leg length difference. All four legs are roughly the same length.

Camels are renowned for their desert adaptations and can survive far longer without water than giraffes. Camels can go weeks without drinking due to physiological adaptations, while giraffes need regular access to water and typically drink every few days.

Snakes lack external ear openings and external ears (pinnae) entirely. They possess internal ear structures and detect airborne and ground vibrations primarily through their jaw bones and body - a sensory adaptation suited to their burrowing and hunting lifestyle.

Giraffes do have long tongues (typically 18-20 inches, not 21 inches), which they use for grasping leaves. However, giraffes cannot actually clean their ears with their tongues - this is anatomically impossible.

Tigers are the heaviest wild cats, with males weighing up to 300 kg. They DO have white spots on the back of their ears (ocelli). Each tiger has a unique stripe pattern - like human fingerprints. In all tiger subspecies, males are larger than females (sexual dimorphism), making A the only correct statement.
