sp2606 [1]

Answer:

<u>Cartilagenous joint</u>

Explanation:

A cartilaginous joint where the bones are joined by fibrocartilage is called a symphysis. Fibrocartilage is very strong because it contains numerous bundles of thick collagen fibers, thus giving it a much greater ability to resist pulling and bending forces when compared with hyaline cartilage. This gives symphyses the ability to strongly unite the adjacent bones, but can still allow for limited movement to occur.

When an action potential arrives at the axon terminal of a motor neuron, which ion channels open?
HACTEHA [7]

Answer:

Calcium voltage gated ion channels

Explanation:

There are two types of ion channels involved in the neuromuscular junction and end plate potentials: voltage-gated ion channel (responsive to changes in membrane voltage which cause the voltage gated ion channel to open) and ligand-gated ion channel (responsive to certain molecules such as neurotransmitters).

The resting membrane potential of a motor neuron goes from -70mV to -50 with a higher concentration of sodium outside and a higher concentration of potassium inside. <em>When an action potential propagates down a nerve and reaches the axon terminal of the motor neuron, the change in membrane voltage causes the calcium voltage gated ion channels to open allowing for an influx of calcium ions. </em>These calcium ions cause the acetylcholine vesicles  to release acetylcholine via exocytosis into the synaptic cleft.

I hope you find this information useful and interesting! Good luck!

Describe the type of plants that serve as pioneer species, intermediate species, and climax community species in secondary succe
MissTica
In secondary succession, the pioneer species are plants that are adapted to exploit disturbances rather than bare rock. They typically include plants such as grasses, birch trees, and fireweed. Organic matter from the pioneer species improves the soil so other trees and plants can move into the area.

Which detail from the excerpt develops the idea that scholars faced many challenges in deciphering the meaning of the
Ratling [72]

Read the excerpt from The Riddle of the Rosetta Stone, by James Cross Giblin.

Another, more complete copy of the same decree that appeared on the Stone was found on a slab at Philae in 1848. Fuller translations of the hieroglyphic text soon followed. A Latin version came out in 1851, a French one in 1867, and an English one in 1871. But many of the hieroglyphs on this slab were missing also, so only a few words and phrases could be added to what was already known from the Rosetta Stone.

Which detail from the excerpt develops the idea that scholars faced many challenges in deciphering the meaning of the decree on the Rosetta Stone?

Answer:

many of the hieroglyphs on this slab were missing

Explanation:

The detail from the excerpt that develops the idea that scholars faced many challenges in deciphering the meaning of the decree on the Rosetta Stone is "many of the hieroglyphs on this slab were missing."

From the available excerpt, it was written that despite many translations of the original text, including the fuller version, the French translation, the Latin version, and the English version, "many of the hieroglyphs on this slab were missing also, so only a few words and phrases could be added to what was already known from the Rosetta Stone."
