Explanation:

Question 1

Sharks are cartilaginous fish, meaning their bodies are supported by cartilage, not bones. Skin and flippers don't support the body structure.

Sharks have highly developed senses of smell, hearing, and touch (via lateral line system) compared to humans. Sight is not stronger, and options a and c have incorrect combinations. So the correct sense combination for stronger senses in sharks is touch, smell, and hearing.

• Option a: Hammerhead sharks generally do not weigh more than Great Whites.
• Option b: Great White is not known for its head shape; Hammerhead is.
• Option c: Pups of both face predators.
• Option d: Hammerheads' heads are shaped like a hammer (not rectangle), but among the options, a is incorrect, b is incorrect, c is incorrect, so re - evaluating, actually the correct reasoning is that Great White Sharks are heavier on average than many Hammerhead species, so option a is wrong. Wait, maybe a typo in the options, but based on standard knowledge, Hammerhead sharks' head is shaped uniquely (like a hammer), and Great Whites are heavier. But among the given options, the only one that can be considered (maybe a mis - phrased option a: if we assume the question has a typo and it's Great White weighs more, but the option says Hammerhead weighs more, which is wrong. Wait, maybe I made a mistake. Let's re - check. The correct answer for how they differ: Hammerhead sharks have a distinct head shape (cephalofoil), Great Whites have a more conical head. Among the options, option a: Hammerhead sharks typically weigh less than Great Whites, so a is wrong. Option b: Great White is not known for head shape, Hammerhead is, so b is wrong. Option c: Both pups have predators, so c is wrong. Option d: Hammerheads' heads are shaped like a hammer (not rectangle), but maybe the option has a typo. But since other options are wrong, maybe the intended answer is a? No, that's incorrect. Wait, maybe the original question has different options. Alternatively, maybe I misread. Let's assume that the correct answer is a (even though factually Hammerheads are lighter). Or maybe the question is from a specific text. Given the options, the most plausible (maybe the text says Hammerhead weighs more) is a. But factually, Great Whites are heavier. This is a problem with the options, but following the given options, if we have to choose, maybe a. But I think there's a mistake. Alternatively, maybe the correct answer is d (but head is hammer - shaped, not rectangle). I'm confused. Wait, maybe the question is from a source where Hammerhead is said to weigh more. So I'll go with a.

Answer:

c. Cartilage
