Carbohydrates are sugars, and they provide energy for all cells. They also provide structure.
Answer:
Motor Cortex
Explanation:
The motor cortex is principal part of the brain that involves motor (motion) functions. The motor cortex's function involves planning, deciding, and executing physical movements.
In 1870 Gustav Fritsch and Edvard Hitzig showed that electrical stimulation of the cerebral cortex of a dog produced movements involuntarily.
This experiment was a crucial event in the development of modern neuroscience.
It became an experimental evidence for cerebral cortex involvement in motor function, the electrical excitability of the cortex, the topographic representation in the brain, and the localization of function in different regions of the cerebral cortex.
When many water molecules come into contact with one another "they get attracted to each other".
<u>Explanation:</u>
When water molecules reach into contact of each other they start attracting each other with proper orientation as the positive end of hydrogen atom of one molecule coordinate or get attached with negative end of oxygen atom of another water molecule. This link also termed as "hydrogen bond".
These attractions or hydrogen bonds showcase the ease of polarity. But the interactions are considered as weak that form between a partial positive charge of hydrogen with a more electronegative atom like oxygen, nitrogen and fluorine.
Answer:
It was originally thought that archaea and eukaryotes were more closely related than bacteria and eukaryotes. However, evidence now supports the fact that both archaea and bacteria were responsible for the formation of more complex cells.
