Answer: This cell will not respond quickly to what work do they need to do.
Signalling will not be strong so, mechanical work won't be done properly.
As mitochondria is mainly responsible for the production of ATP, these cells will not produce enough energy.
There may be difficulty in the contraction of this cell.
Homeostasis may not be maintained properly.
Answer:
Unconditioned stimulus.
Explanation:
Classical conditioning may be defined as a type of learning procedure in which the biological procedure is used to pair up with the previous nerve stimulus. This stimulus result in the response of an individual.
The Pavlov experiment with the dog explains the process of classical conditioning. The ringing of bell (conditioned stimulus) is paired with unconditioned stimulus (meat presentation).
Thus, the meat presentation is unconditioned stimulus.
Answer: Option D: Neuromuscular junction
Explanation:
This is the site of transmission of chemical signal also known as a chemical synapse between a neuron and a muscle fibre. Most of the time the chemical released which is a neurotransmitter is acetylcholine. When released, it stimulates the release of calcuim ions present in the sarcoplasm: an endoplasm like structure in the muscle fiber that contains calcium ions.
A reef is a ridge of a rock of any type of land that extends some distance just under the surface of the water. A coral reef is a lot of calcium carbonate that is also made up of living creatures. A coral reef is created when a small amount of dead coral turns into calcium carbonate. This process is very slow. The famous reefs are the Great barrier Reef of Austria and Belize and Cayman Islands.
Wave actions are usually not a problem due to hard coral reefs. The reef reduces a wave energy. But sometimes waves can break off or flatten large portions of coral reefs, forming grooves in once circular reef. The higher areas between the grooves are known as buttresses and may grow together at the top producing arches.
Answer: Landform that develops on coral reefs as a result of wave action are Arches.
