Flat fish have both eyes on top of their head and swim horizontally
Correct Answer
A. True
Explanation
Flat fish, such as flounders and sole, have a unique adaptation where both of their eyes are located on one side of their head. This allows them to lie flat on the ocean floor while camouflaging themselves. Their flat body shape and sideways swimming motion enable them to blend in with the sandy or muddy seabed. This adaptation helps them remain hidden from predators and also allows them to ambush their prey more effectively. Therefore, the statement "Flat fish have both eyes on top of their head and swim horizontally" is true.
2.
Compared to meat, fish has more connective tissue.
Correct Answer
B. False
Explanation
Fish actually has less connective tissue compared to meat. Connective tissue is responsible for the toughness and chewiness of meat, and fish generally has a softer and more tender texture due to its lower connective tissue content. This is why fish is often considered to be a more delicate and easily digestible protein option compared to meat.

Therefore, the statement is true and indicates a valid criterion for assessing the freshness of a fish fillet.
5.
Pan frying and deep frying should be done with leaner fish
Correct Answer
B. False
Explanation
Pan frying and deep frying can be done with any type of fish, not just leaner fish. The choice of fish for frying depends on personal preference and the desired texture and flavor. Fattier fish, such as salmon or mackerel, can also be delicious when pan fried or deep fried, as the high heat helps to render the fat and create a crispy exterior. Therefore, the statement that pan frying and deep frying should only be done with leaner fish is false.
6.
Lobsters and clams should be cooked within three days after they have died.
Correct Answer
B. False
Explanation
Lobsters and clams should be cooked within a day or two after they have died, not within three days. This is because seafood starts to deteriorate quickly after death, and consuming it after three days can pose a risk to one's health. It is important to ensure that seafood is fresh and properly stored to avoid any potential foodborne illnesses.
7.
A demi vegetarian is a vegetarian that eats fish.
Explanation
A demi vegetarian is a term used to describe someone who follows a primarily vegetarian diet but occasionally includes fish in their meals. This means that they abstain from consuming meat from land animals, such as poultry or red meat, but still include fish and seafood in their diet. This dietary choice is often made for health or environmental reasons, as fish is a lean source of protein and can provide essential nutrients. However, it is important to note that the term demi vegetarian is not widely recognized or used, and the more common terms for this dietary choice are pescatarian or semi-vegetarian.
