O revestimento do urso-pardo é...
Correct Answer
A. Pele com pelos.
Explanation
The correct answer is "pele com pelos." This is because bears, including brown bears, have a thick coat of fur that covers their skin. Fur helps to insulate them and keep them warm in cold weather. Bears do not have an exoskeleton like insects, nor do they have scales on their skin.

O revestimento do salmão é...
Correct Answer
B. Pele com escamas dérmicas.
Explanation
The correct answer is "pele com escamas dérmicas." This is because salmon have a unique skin structure that includes dermal scales, which are bony structures embedded in the skin. These scales provide protection and help reduce drag in the water. The term "dérmicas" refers to the fact that these scales are of dermal origin, meaning they develop from the dermis layer of the skin.

Correct Answer
B. Carapaça com quitina e calcário.
Explanation

Correct Answer
C. Exosqueleto de quitina.
Explanation
The correct answer is "exosqueleto de quitina." This is because the exoskeleton of a grasshopper is made up of a tough, flexible material called chitin. The chitinous exoskeleton provides support and protection for the grasshopper's body, allowing it to move and survive in its environment.

Qual das opções corresponde a uma não função do revestimento do escorpião?
Correct Answer
D. Manter a temperatura corporal.
Explanation
A resposta correta é "Manter a temperatura corporal". O revestimento do escorpião não tem a função de regular a temperatura do corpo. Essa função é realizada por outros mecanismos fisiológicos, como a regulação metabólica e o comportamento de busca de abrigo ou exposição ao sol. O revestimento do escorpião é responsável principalmente por proteger o corpo contra impactos, manter a forma do corpo e evitar a desidratação.
11.
O tipo de locomoção do tubarão é...
Correct Answer
C. Natação.
Explanation
The correct answer is "natação" because sharks are known for their ability to swim in the water. They have streamlined bodies and powerful tails that allow them to move efficiently through the water. Sharks rely on swimming to hunt for prey, escape from predators, and migrate long distances. Therefore, swimming is the most appropriate form of locomotion for sharks.
12.
O tipo de locomoção do urso-polar...
Correct Answer
A. Marcha.
Explanation
The correct answer is "marcha" because polar bears primarily move by walking or marching. They have large, strong limbs and padded feet that are well adapted for walking on land and ice. While they can also swim and climb, these modes of locomotion are not as common or efficient for polar bears as walking. Therefore, "marcha" is the most appropriate choice for the type of locomotion exhibited by polar bears.

O tipo de locomoção da águia é...
Correct Answer
B. Voo.
Explanation
The correct answer is "voo" because eagles are known for their ability to fly. They have strong wings and a light body structure that allows them to soar through the air for extended periods of time. Eagles use their wings to glide, hover, and dive, making flight their primary mode of locomotion.

Uma adaptação das aves ao voo é...
Correct Answer
A. Esterno em forma de quilha.
Explanation
A adaptação das aves ao voo é o esterno em forma de quilha. O esterno é um osso localizado no peito das aves, e a quilha é uma projeção em forma de lâmina que se estende para baixo a partir do esterno. Essa estrutura muscularizada e em forma de quilha é fundamental para fornecer uma área de fixação maior para os músculos das asas, permitindo um voo mais eficiente. A quilha também ajuda a estabilizar a ave durante o voo, garantindo um melhor controle e equilíbrio.

Uma adaptação dos peixes à natação é...
Correct Answer
B. Barbatanas.
Explanation
The correct answer is "barbatanas". This is because barbatanas are adaptations of fish for swimming. They are fin-like structures that help fish maneuver and propel themselves through water. Barbatanas provide stability, control, and propulsion, allowing fish to swim efficiently. They come in various shapes and sizes, depending on the species of fish and their swimming habits. Overall, barbatanas are essential for fish to navigate their aquatic environment effectively.
