<span>Because they are composed of material that is denser than that of the continental crust. As such oceanic crust is less buoyant than continental crust and so where oceanic crust collides with continental crust, the oceanic rust tends to be forced beneath the continental crust.</span>
The triceps brachii muscle attaches to the olecranon process of the ulna crossing the posterior side of the elbow joint. that will allow the triceps to be an <u>Extensor </u>of the elbow joint.
- Directly affected is the common extensor tendon, which arises from the lateral epicondyle of the elbow.
- The common extensor tendon is made up of the extensor carpi radialis brevis (ECRB) and longus, extensor digitorum, extensor digiti minimi, and extensor carpi ulnaris.
- The main elbow flexors are the biceps brachii, brachialis, and brachioradialis.
- The main elbow extensor is the triceps brachii. Although it is also believed that the anconeus contributes to elbow extension.
- The proximal articular region of the ulna is called the olecranon. It creates the larger sigmoid notch, which articulates with the humerus to allow for elbow flexion and extension, together with the coronoid process.
- The main point of attachment for the forearm's extensor muscles is the common extensor tendon. This promotes forearm supination and allows finger extension.

Budding is the asexual mode of reproduction. In budding there is no involvement of male and female gamete. Hence budding is a type of asexual reproduction.
There will be more acid particles to interact with the limestone at higher concentrations hence the rate of reaction increases.
The question is incomplete but I will try to help you the much I can. If you have carried out the experiment properly, you will notice that the rate of reaction increases as the concentration of the acid increases.
This is because, if the amount of limestone is held constant and the concentration of acid is increased, there will be more acid particles to interact with the limestone at higher concentrations hence the reaction proceeds faster.

It helps because say the hinge joint had a structure as one of a ball-and-socket joint the knee (where the hinge joint is located) wouldn't bend it would rotate/ spin like our shoulders. This is how classifying joints according to their structure and function can/ may help describe human movement.
