Explanation:
A space between the two bones of the synovial joint is called the joint cavity. It allows the synovial joints to move freely. The layer of hyaline cartilage covers the bones of the synovial joints. This is called articular cartilage. It forms a slippery surface to cover the bones. Due to the presence of cartilage, the friction is reduced between bones of the joints during movement.
Synovial joints may also have accessory ligaments present outside or within the articular capsule of the joints. Nerve endings are present in the articular capsule and the related ligaments of these joints. Similarly, blood vessels enter the ligaments and articular capsule of these joints.
Answer:
A.)are ectothermic organisms with variable body temperatures.
Explanation:
Invertebrates animal are animals that lack a backbone, Land invertebrates include insects,spiders, centipedes ,coelenterate, an arthropod, mollusc and the rest.
Ectotherms are also called called cold-blooded animal because their bl body temperature regulation is dependendent on external sources, such as sunlight or a heated rock surface. Some of the examples of ectotherms are fishes, amphibians, invertebratesand reptiles. The aquatic ectotherms body temperature is usually compare closely to the temperature of the surrounding water
Ectothermic species that lives in temperate regions usually experience rapid and potentially stressful changes in body temperature simply because of weather changes even among amphibians there is variation in their temperature
It is believed that naturally occurring periods of temperature variation negatively impact amphibian health.
