Olds and Milner showed that electrical stimulation of particular brain regions could have a reinforcing effect.
<h3>Electrical brain stimulation</h3>
it is commonly known as focal brain stimulation (FBS), is a type of electrotherapy used in clinical neurobiology and research to activate a neuron or neural network in the brain by either directly or indirectly stimulating its cell membrane with an electric current.
<h3>What is the purpose of brain electrical stimulation?</h3>
- Electrical stimulation can be used to alter how the brain functions because electrical charges are what cause brain activity.
- Brain stimulation has been used to treat stress and mood disorders, and it can even make it easier for people to remember things, solve puzzles, and pay attention.

The correction is B.
The respiratory system is the one that is responsible for transportation of oxygen from the outside to the lungs and the reverse transportation of carbon dioxide from the body to the atmosphere. The muscular system is responsible for the contraction of muscles around the air passages during respiration. These two systems are negatively affected in asthma patients during respiration.
This behavior represents the dormancy.
Dormancy is a period in life cycle of an organism when growth, development, and physical activity are temporarily stopped. Period of dormancy minimizes metabolic activity of an organism and therefore helps them to conserve energy. So, aquatic burrowing frogs get into energy-saving mode as long as resources are scarce.

A newly discovered unicellular eukaryotic organism that moves using a flagellum would be best classified in the Protista kingdom. Protists are eukaryotic organisms that cannot be classified as a plant, animal, or fungus. They are mostly unicellular, but some, like algae, are multicellular. I hope this is the answer that you were looking for.
