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.
Rosalind Elsie Franklin was an English chemist and X-ray crystallographer who made contributions to the understanding of the molecular structures of DNA, RNA, viruses, coal, and graphite. Although her works on coal and viruses were appreciated in her lifetime, her contributions to the discovery of the structure of DNA were largely recognised posthumously. Born to a prominent British Jewish family, Franklin was educated at a private day school at Norland Place in West London.
The sounds of music are related to trigonometric functions in the fact that the sound can be measured according to the angles of the sound waves.
<h3>What is sound?</h3>
Sound is a disturbance on a specific media (e.g., air) that travels with a particular frequency and amplitude.
Sound amplitude is represented by the height of the wave, whereas sound frequency is referred to as the period of time between waves.
In conclusion, the sounds of music are related to trigonometric functions in the fact that the sound can be measured according to the angles of the sound waves.
The graph below shows how trigonometric functions are associated with sound waves.
The trigonometric function used in the graph to understand the movement of sound waves is Y=sin(X).

Answer:
The correct answer is - diatom (protist)
Explanation:
The characteristic described by the professor is most similar to the characteristic of aquatic protist - diatoms. Diatoms are the aquatic protist fall into the eukaryotic type of organisms.
These organisms are single-celled and can not swim on their own. They are a primary producer as they do not depends on others for their food and energy and synthesized themselves.
