Psychoactive drug or psychotropic substance is a chemical substance that acts primarily upon the central nervous system where it alters brain function resulting in temporary changes in perception, mood, consciousness and behavior.
Answer:
determination is the process in which embryonic stem cells commit to one specialized function. differentiation is the process in which cells develop their specialized shapes and functions. determination has to happen for differentiation to occur.
The work of Broca, Fritsch, Hitzig, and Ferrier demonstrated localized brain function, which was similar to predictions made by phrenologists. Phrenology is a pseudoscience.
Phrenology is a pseudoscience aimed at measuring bumps on the skull to predict personality traits.
Eduard Hitzig and Gustav Fritsch demonstrated that electrical stimulation of specific areas of the cerebral cortex could trigger movement.
Broca's area is an area located in the frontal part of the left brain hemisphere discovered by Paul Broca, who observed how this area has a fundamental function for the generation of speech in humans.
Finally, David Ferrier was a neurologist who discovered a series of motor fields within the cerebral cortex of monkeys.

Let's say the lethal gene is represented with l, and the normal gene is represented with L.
A person with Ll, a carrier, CAN produce offspring with the genotype ll (lethal) if they have children with another carrier. (a 25% chance lethal, 50% carrier, 25% perfectly normal)
