Seismicity along divergent plate boundaries is concentrated along rocky areas away from the rift zones.
An oceanic ridge marks divergent plate boundaries in the ocean basins. It is broad, fractured swell with a total length of 70,000 km. Basaltic volcanism and shallow earth quakes are concentrated along the rift zone at the ridge crest. The ridge's characteristics depend upon the spreading rate.
The subclavian artery is renamed as axillary artery after it passes over the lateral border of the first rib.
<h3>What is axillary artery?</h3>
- The subclavian artery continues as the axillary artery at the lateral aspect of the first rib, serving as the primary artery of the upper extremity.
- The artery has three sections based on its proximity to the pectoralis minor muscle, each of which has six major branches.
- A sizable muscle vessel that passes through the axilla is called the axillary artery.
- It is in charge of delivering oxygen-rich blood to the upper limb as well as to a portion of the scapula's and upper lateral thorax's musculocutaneous system.
- As a result, two primary arteries rather than one supplied the upper limb's axillary region in particular with arterial blood on both sides.
- These two arteries may be lingering branches of the capillary plexus of the growing limb buds because they came from the first portion of the axillary artery.

Answer;
Without the keystone species, the rocky inter-tidal ecosystem would be dramatically different or cease to exist altogether
Explanation;
Keystone species have low functional redundancy. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche.
For instance; the starfish Pisaster ochraceus is a keystone species in the rocky marine inter-tidal communities off the northwest coast of North America. It feeds on the mussel Mytilus californianus and is responsible for maintaining much of the local diversity of species within certain communities.
