When tissues are harmed by bacteria, trauma, heat, or any other cause, an inflammatory reaction occurs.
<h3>What happen when a honey bee stings?</h3>
When a honey bee stings or a disease infects damaged cells, chemicals are released. chemicals are a group of substances that include prostaglandins, histamine, and bradykinin. These substances promote swelling by forcing blood vessels to leak fluid into the tissues.
During the inflammatory reaction, the following processes occurred:
Redness, swelling, and loss of function are all symptoms of heat.
Inflammation is the body's natural defense system. Damaged cells, irritants, and infections are recognized by the immune system, white blood cell kills the antigen and stimulates the other defense cell to act. this process is called a macrophage.

Answer:
1. opening Voltage gated channels
2. Calcium
Explanation:
The signals are transmitted in the neurons in the form of electrical signals and which are transformed into the chemical signals at the synaptic cleft.
The electrical signal is transformed into a chemical signal when the electrical impulse reaches the terminal of the axon and opens the calcium voltage channels. The calcium which is present in a higher amount than inside enter into the terminal and allows fusion of the synaptic vesicle carrying neurotransmitter and the neurotransmitter is released into the synapse.
The neurotransmitter then binds the receptors and initiates the electrical impulse in the postsynaptic neuron.
Thus, opening Voltage gated channels and Calcium is the correct answer.

B. mixture in which its components retain their identity
Answer:
meter
Explanation:
The following equation will be used to solve this question -
Velocity is zero.
Removing out the nullified terms from the above equation, we get -
meter
Hence, top of the liquid in the bottle must be at a height of meter.
