<span>The answer would be: requires an outside energy source for a nonspontaneous chemical reaction to occur
<span>
An electrolytic cell is a cell that could change electric energy into chemical energy. It uses electric to induce a nonspontaneous chemical reaction.
</span><span>Electrolytic cells are the </span>opposite of voltaic cells which will cause a spontaneous chemical reaction that produces electricity. </span>
The renal tubule would be the vessel within the nephron loops that functions to collect ions and water back into the blood. In addition, these vessels are the one responsible for emptying the collecting duct and reabsorbs salts present in the bloodstream and disperses it back to the blood.
<span>The main difference between adaptice radiation and other forms of speciationn is : Adaptive radiation happens over a relatively short time.
In natural process of speciation, the perfect mutation could occur within millions of years. In adaptive radiation, the mutation could instantly happenes not long after the radiataion process</span>
Answer:
true
Explanation:
Cerebrospinal fluids is a colorless fluid that is secreted in the choroid plexus,and circulates in the ventricles system and sub -aranchinoid space of the brain and spinal cord. its provides nutrients to the surrounding neurons, cushions the effects of trauma, pressure, acts as buffer and provides protection through immune system .
it plays a vital role in regulating blood flow, through a process called cerebral auto regulation,This is needed to maintain efficient cerebral blood flow of oxygen and other metabolites, and withdraw of metabolic wastes from the brain.
in order to analyze it to diagnose some neurological diseases its sample is usually taken out in a process called lumbar puncture.
