Answer;
-Axon; dendrites
When a neural signal is transmitted, it leaves the axon of the first neuron and is received by the dendrites of the second neuron.
Explanation;
-Electrical events propagate a signal within a neuron, and chemical processes transmit the signal from one neuron to another. The chemical process of interaction between neurons occur at the end of the axon, in a structure called synapse.
-When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite.
The risks of indoor cooking with biofuels and poor ventilation can be reduced through: better ventilation.
<h3>What is chemical pollution?</h3>
Chemical pollution can be defined as the contamination of an environment or waterway, especially through an emission of poisonous, hazardous, and toxic chemical compounds (substances) by humans and various industries.
According to the Environmental Protection Agency (EPA), chemical pollution is a change to waterways and the atmosphere which are mainly caused as a result of human activity.
In this scenario, we can reasonably infer and logically deduce that the risks of indoor cooking with biofuels and poor ventilation can be reduced through better ventilation in the cooking area, so as to efficiently and effectively diffuse the gases.
