An exposure to sarin or sarin like chemical will caused the sarcoplasmic reticulum to be continuously stimulated by the continual electrical signal. This will open the calcium channels and allows the calcium ions to bind continuously with troponin. Sarin is an organophosphorus chemical which is highly poisonous. It is used as a chemical weapon of destruction.
The role of deep-sea coral reefs in the environment is to provide critical habitat for many other organisms. So, the correct option is C.
<h3>What do you understand about Coral reefs?</h3>
A coral reef is an underwater ecosystem characterized by reef-building corals.
Coral reefs provide critical habitat for many invertebrates and fishes. These organisms are also known as cold-water corals, as they are found in the deeper and darker part of the ocean where the temperature is extremely low.
Therefore, the role of deep-sea coral reefs in the environment is to provide critical habitat for many other organisms.

Answer:
Digestion, excretion and transportation of substances.
Explanation:
Chemical reactions such as breakdown of food, cleaning of blood and absorption of nutrients and digestion are the activities that our body done with the use of energy. Digestion of food needs energy for the breakdown of food with the help of several enzymes. Transportation of waste materials and other substances also needs energy. Our cells absorb nutrients with the help of energy molecules through active transport.
Answer:
time (t) = 2.69 sec
Explanation:
Given that;
The final top speed of 3.96 m/s ( final velocity V) = 3.96 m/s .
The initial speed is 0; &
The acceleration (a) = 1.47 m/s²
We can determine how much time does it take the snake to reach its top speed by using the equation of motion;
V = U +at
3.96 = 0 + (1.47×t)
3.96 = 1.47t
t = 
time (t) = 2.69 sec
∴ It took the snake 2.69 sec to reach the its top speed.
A cell would use exocytosis to accomplish this. Please mark Brainliest!!!
