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.
A renewable resource is a resource that can be renewed/or replinished meaning the Sustainably Harvested seafood must be your answer. Natural gas takes too long to replenish so it is considered non-renewable. You can bring back sand once it's gone nor Methane Hydrates.
Sustainably harvested seafood
hope this helped
Option A
This option represents only chloroplast which is a cell organelle.
Option B
This option only talk about cell division.
Option C
This option is related to cellular respiration which is carried out in mitochondria.
Option D
It tells us that different tissues are connected like bone connect with muscle cells.
Conclusion
The correct option is D which provide the best evidence for the idea that multi cellular organisms are composed of organized arrangements of differentiated cells.

Answer:
i think its primary succession
Explanation:
<span>The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay. In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years. This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago. After 5,730 years, the amount of carbon 14 left in the body is half of the original amount. If the amount of carbon 14 is halved every 5,730 years, it will not take very long to reach an amount that is too small to analyze. When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is –0.693.</span>
