Answers

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.

Answers

Colchicine is a toxin that binds to tubulin proteins and prevents microtubules from elongating. What effect might this have on dividing cells

Answers

The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.

Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.

During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.

When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.
