Functional Morphology & Biomechanics Quiz

Birds have the ability to fly and soar through the air using their wings.

Insects fly by using their wings, not by using jetpacks or riding on other animals.

Tsetse flies have different wings than thrips flies primarily because of their size difference. Tsetse flies are much larger in size compared to thrips flies, leading to the necessity of having different wing structures for their respective activities.

Insects use their wings and powerful muscles to achieve flight, not propeller and jet engines, gears and wheels, sails and oars.

Stresses animals endure can include a variety of factors, such as environmental changes, predation, disease, and competition for resources.

Strength can be defined in various ways such as physical power, mental fortitude, or emotional resilience. While image might be one aspect of strength, it is not the only defining characteristic.

Pliant materials are known for their ability to easily bend or flex without breaking. Examples such as rubber, plastic, and elastic are commonly used for their flexibility. The incorrect answers describe materials that are not typically considered pliant due to their rigidity or lack of flexibility.

Tensile materials are specifically known for their ability to stretch without breaking, making them ideal for applications such as elastic bands, ropes, and clothing fabrics. Materials like rubber, nylon, and polyester are commonly used in various industries due to their tensile strength.

Rigid materials are known for their stiffness and resistance to deformation, unlike soft, liquid, and gaseous materials which exhibit different physical properties.

Elastic materials can return to their original shape after being deformed, while plastic materials are permanently deformed when subjected to stress. The properties of color, density, and length do not specifically define whether a material is elastic or plastic.

Young's Modulus is the ratio of stress to strain in a material, commonly expressed as E = stress / strain. The correct formula is not a mathematical expression but a concept represented graphically.

Mild steel is known for its high stiffness and strength compared to pig's aorta and silk.

The question is asking for the tensile strength of specific materials, so providing random values as incorrect answers makes the question challenging and tests the knowledge of the individual.

Laminar structure in bones provides strength by distributing stress more evenly, durability by resisting bending and twisting forces, and resistance to fractures by increasing the bone's toughness. This structural arrangement is crucial for the proper functioning and support of the skeletal system.

Muscle strength depends on various factors such as genetics, nutrition, and exercise. While age and exercise frequency can play a role in muscle strength, brain power does not directly influence muscle strength.

The musculo-skeletal system requires a combination of various nutrients and elements to function effectively. While water, vitamin C, and protein are essential for overall health, they do not specifically meet the requirements of the musculo-skeletal system which includes bones, muscles, ligaments, and tendons.

In this question, we are looking for the specific terms related to hydrostatic skeleton. A resistor is not relevant to the hydrostatic skeleton concept, and neither is an elbow joint. The pair of antagonistic muscles in a hydrostatic skeleton are typically found in organisms like earthworms or jellyfish, which use muscle contractions in fluid-filled cavities to generate movement.

The three classes of levers are differentiated by the positioning of the fulcrum, load, and effort. In Class 1 levers, the fulcrum is placed between the load and effort. In Class 2 levers, the load is between the fulcrum and effort. In Class 3 levers, the effort is between the fulcrum and load.

A lobster's claw represents a Class 3 lever because the effort arm is shorter than the resistance arm, allowing for increased force at the cost of decreased distance.

Leaping ability in animals is influenced by various factors including body size, muscle strength, and biomechanics. While fleas may have unparalleled jumping ability relative to body size, it does not directly translate to identifying the animal with the highest overall jumping ability.
