Answer:
The activity which causes the least amount of wetland and estuary degradation when it occurs near the coast is:
A. dune grass rehabilitation
Explanation:
This is actually a rehabilitation effort, unlike the other three options that cause land degradation. A dune grass rehabilitation accretes sand and minimizes the rates of beach erosion. The program tries to protect coastal infrastructure and upland properties from storm damage by planting vegetation, fencing off sensitive areas, blocking storm surge, creating dune walkways, and absorbing wave energy. During dune grass rehabilitation, activities that adversely affect the dunes are avoided.

Explanation:
English-The geocentric model says that the earth is at the center of the cosmos or universe, and the planets, the sun and the moon, and the stars circles around it. The early heliocentric models consider the sun as the center, and the planets revolve around the sun.
Spanish-El modelo geocéntrico dice que la tierra está en el centro del cosmos o universo, y los planetas, el sol y la luna, y las estrellas giran a su alrededor. Los primeros modelos heliocéntricos consideran al sol como el centro y los planetas giran alrededor del sol.
Answer:
Yes, the nodes of Ranvier spaced equally along the axon to allow the action potential at first node to cause depolarization of second node.
Explanation:
Yes, nodes of Ranvier are equally spaced along the length of the axon. When an action potential reaches the first node, it generates the ionic movement in the cytosol and extracellular fluid so as to depolarize the membrane up to the threshold at the second node. This opens the voltage-gated Na+ channels at the second node to allow the ions to flow followed by generation of an action potential at the second node.
Now, as the action potential is generated at the second node, the stimulated ionic movement opens the voltage-gated Na+ ion channels at the third node and the process is repeated. Hence, equally spaced nodes of Ranvier ensure that the action potential at one node can stimulate the depolarization at the next node.
Answer:
The answer is letter D, The storms cause wind and waves that move the sand from one place to another.
Explanation:
Along the coastline of Florida are their <em>beaches and barrier islands. </em><u>These islands are very important for the survival of plants and animals. </u>However, whenever a hurricane or a storm hits the area, it causes a dramatic change in the shape of the place. This is, primarily, because the storm causes the forces of wind and waves to move the sand from one place to another.
The movement of these can be towards or away from the mainland. <em>The fast movement</em> <u>causes the sand in the area to be deposited away from the shore,</u> thus creating sandbars. <em>The slow movement</em> <u>causes the sand from the sandbars to return back to the shore.</u>
