Marine Biology (How Much Do You Know?)

Explanation
Marine biology is the study of saltwater environments. It involves the examination and understanding of various marine organisms, their behavior, habitats, and interactions with their surroundings. This field of science focuses on studying the biodiversity, ecology, and conservation of marine life, as well as the physical and chemical properties of the ocean. Marine biologists conduct research, collect data, and analyze the marine ecosystem to gain insights into the complex and diverse world beneath the sea.

Explanation
Mammals with teeth, such as Sharks and Orcas, are indeed vicious animals. This is because their teeth are adapted for hunting and capturing prey. Sharks have rows of sharp, serrated teeth that they use to tear apart their prey, while Orcas have large, powerful teeth that they use to grab and kill their prey. These adaptations make them highly effective predators in their respective marine environments.

Explanation
Orcas, also known as killer whales, are actually a species of dolphins. Despite their name, they are not whales but the largest members of the dolphin family. They are highly intelligent, social creatures that are known for their distinctive black and white coloration. Orcas are found in oceans all over the world and are known for their powerful hunting abilities and complex social structures. Therefore, the statement "Oracas are actually dolphins" is true.

Explanation
The Orca is more commonly referred to as the Killer Whale. It is known as the "Wolves of the Sea" because they are highly social and intelligent animals that often hunt in packs, similar to how wolves hunt in packs on land. The term "Killing Machines" and "Whale Killers" are also used to describe the Orca due to their predatory nature and ability to take down large prey, including other whales.

Explanation
The given answer options suggest different time periods for the duration of someone's interest in Marine Biology. Option 1-12 months indicates a relatively short-term interest, possibly indicating a recent fascination or exploration of the subject. Option 1-8 years suggests a longer duration of interest, indicating a more established passion for Marine Biology. The option "Longer than that" implies an even longer duration of interest, potentially indicating a lifelong passion or career in Marine Biology.
