They use the design of Nonexperimental Research.
<h3><u>What is Nonexperimental research?</u></h3>
- Research is defined as the creation of new knowledge and/or the use of existing knowledge in a new and creative way so as to generate new concepts, methodologies and understandings. This could include synthesis and analysis of previous research to the extent that it leads to new and creative outcomes.
- Nonexperimental research is research that lacks the manipulation of an independent variable, random assignment of participants to conditions or orders of conditions, or both. In a sense, it is unfair to define this large and diverse set of approaches collectively by what they are not.
Examples of Nonexperimental research.
- Commonly, non-experimental studies are purely observational and the results intended to be purely descriptive. For example, an investigator may be interested in the aver- age age, sex, most common diagnoses, and other characteristics of pediatric patients being transported by air.

Answer:
They don't need Gas.
Explanation:
They run on electricity
The electricity is stored in batteries
Electric cars still need regular break fluid changes
Non-rapid-eye-movement sleep (NREMS), rapid-eye-movement sleep (REMS), and W are regulated by several Neurotransmitter systems and a number of diffusible or circulating factors.
Neurotransmitters are chemical messengers that your body can't function without. Their job is to carry chemical signals (“messages”) from one neuron (nerve cell) to the next target cell. The next target cell can be another nerve cell, a muscle cell or a gland.
The DA-containing cells of the VTA and SNc mission to the basal ganglia and the prefrontal cortex, even as these correspond to the PAG mission predominantly to the BFB and midline thalamus. moreover, OX-containing neurons bring projections to the entire forebrain and brainstem arousal structures. three as pointed out by using España and Scammell, four isolated activations of every of the arousal systems already provoke W. but, below regular situations, all of them participate in the occurrence of behavioral and electroencephalographic (EEG) arousal. This depends, in element, on the interconnections of maximum W-promoting structures. similarly, the systems that promote W inhibit neural structures located inside the brainstem and hypothalamus that promote and/or induce NREMS and REMS.
