I needa know how to approach this chick in this gym someone give me some wisdom, name the water resource from where river originate. Because of the dangers, molting animals usually seek shelter during the process in an attempt to lessen their vulnerability. The hexagonal disks are horizontally stacked in a formation similar to that of a brick wall, giving the material great strength. The cement layer B. Bones, when supported by the function of muscles, deliver the capacity of locomotion (movement). The femur and pelvis form the hip joint at the proximal end. The tibia, or shinbone, is a large bone of the leg that is located directly below the knee. They have a variety of functions: In addition to delivering nutrients from choanocytes to other cells within the sponge, they also give rise to eggs for sexual reproduction. Endotherms & ectotherms (article) | Ecology | Khan Academy It improves knee extension by reducing friction. Spongy tissue is found on the interior of the bone, and compact bone tissue is found on the exterior. Lengthening the body extends the anterior end of the organism. These different cell types in sponges are shown in (Figure). Cancellous bone is typically found at the ends of the long bones as well as the rubs, skull, pelvic bones and the vertebrae of the spinal column. E) All of these are essential for a completely terrestrial existence. B. Eukaryote 7. They are characterized as marine animals with spiny endoskeleton Due to the physical properties of the non-living exoskeleton structure, there are restraints on the possibilities of growth. Simple sponge body plan and cell types. { "12.01:_Chordates" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "12.02:_Placental_Mammals" :

In arthropods, biomineralization is most commonly used to harden the shells of crustaceans such as crabs, shrimp and woodlice. The forearm extends from the elbow to the wrist and consists of two bones: the ulna and the radius. answer choices. Instead of bone or cartilage, it consists of a cavity called the coelom, which is filled with a gelatinous substance called mesohyl, and is supported by fluid pressure. Solution: The phenomenon of production and emission of light by an organism as a result of a chemical reaction during which chemical energy is converted to light energy is called bioluminescence. Osmotic Regulation and Excretion, Chapter 24. A) the appearance of jaws. It does not articulate with the femur and does not bear weight. The female pelvis is tilted forward and is wider, lighter, and shallower than the male pelvis. The interior procuticle is made primarily from chitin, a translucent, fibrous material consisting of modified, nitrogen-containing polysaccharides. There are at least 5,000 named species of sponges, likely with thousands more yet to be classified. Shortening of the muscle changes the relationship of the two segments of the exoskeleton. The vertebral column contains 26 bones, and it surrounds and protects the spinal cord. This type of skeletal system is found in soft-bodied animals such as sea anemones, earthworms, Cnidaria, and other invertebrates (Figure1). The names of the spinal curves correspond to the region of the spine in which they occur. Some of the spicules may attain gigantic proportions. Over generations of evolution, females with a wider pubic angle and larger diameter pelvic canal reproduced more successfully. Which of these organisms has an endoskeleton? A.) Beetle
