Here we will discuss Damage to infrastructure in the 2010 Haiti earthquake.
Toussaint Louverture International Airport:
If we talk about the focus point of the Haiti earthquake that hit the Haiti on 12th january, 2010, then it was around 6 miles away from Toussaint Louverture International Airport.
Since the center was so near to airport that is why airport suffered from alot of damage. The control tower of the airport was almost completely destroyed due to which any radio communication became impossible. There was heavy power outrage due to damage caused to the power lines and due to this lightening system of the airport was completely shutdown. was damaged. However, the taxiways, runways and apron parts of the airport were operational at even that time of crisis.
Due to immense amount of damaged caused to Toussaint Louverture International Airport, all the relief bringing planes were diverted to other airports of the city.
The reconstruction and rehabilitation of the airport was started during 2010. It included the restoration and renovation of arrival and departure halls that were previously completely devastated. The renovation os falls included installation 16 new stations and three large baggage carousels and in the immigration room, There was also a significant explansion in the custom rooms.
However, the damage caused to Toussaint Louverture International Airport dur to 2010 Haiti earthquake is still considered as the destruction of major landmark due to earthquake.

Upwelling bring up nutrients (deep sea water is rich in nutrients), this supports the growth of plankton and seaweed. This then provides food for fish, marine mammals, and birds.
Answer:
D. Calcium ions.
Explanation:
Here we are talking about the mechanism of muscle contraction. The most accepted theory of muscle contraction is sliding filament theory. It was given by Huxley and Huxley. During the process actin filaments slides over myosin filament by forming cross bridges. The sequence of events are as follows:
a. An action potential propagates through the motor nerve and reach the nerve endings on the muscle fiber at neuro-muscular junction.
b. Neurotransmitter called acetylcholine is released by the nerve endings.
c. Acetylcholine binds to the receptors on muscle fiber and opens the gated channels which causes flow of Na+ ions into the muscle fiber.
d. This influx of sodium ions initiates an action potential in the muscle fiber which reaches the T- tubules or transverse tubules. Here it causes the sarcoplasmic reticulum to release large amounts of calcium ion.
e. Calcium ions are responsible for initiating the attractive forces between actin and myosin filaments. Cross bridges are formed, actin slides over myosin causing the contraction of muscle.
