The pectoral girdle articulates with the axial skeleton only at the Sternoclavicular ligament<span>. The pectoral girdle connects the upper limbs to the axial skeleton and serves as the attachment site for the muscles of the upper back, chest and neck. The clavicle is the only long bone that lies in a horizontal position in the body. it has three regions; the medial end, the lateral end, and the shaft. The medial end has a triangular shape and articulates with the manubrium portion of the sternum. This forms sternoclavicular joint, which is the only bony articulation between the pectoral girdle of the upper limb and the axial skeleton. </span>
Answer:
Release of large numbers of eggs/sperm into the water during reproduction cycles.
Explanation:
Adaptation may be defined as the change in the physical, physiological and chemical changes in the organisms that helps them to survive in their environment.
The organisms living in the rocky intertidal zone shows adaptations as they are more darker in color and has simple body organisation. The algae,crabs and snails live in the intertidal zone. They have small number of offspring that protect them from the predators.
Thus, the answer is release of large numbers of eggs/sperm into the water during reproduction cycles.
Answer:
The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. ... At convergent boundaries, plates collide with one another.
Microtubules are composed of two different types of tubulin. Namely, these simpler units are called alpha-tubulin and beta-tubulin. These subunits are essentially tightly bound together to form heterodimers. In the microtubule structure, they are arranged in an organized manner in such a way that they in parallel direction with protofilaments.
