Which of the following is a part of both geocentric model and heliocentric model? earth is the center of the solar system. the sun is the center of the solar system. astronomical bodies travel in straight paths. the bodies in space move in circular orbits.

The correct answer is option D, The bodies in space move in circular orbits.

Reason -

In a geocentric model it is believed that all planets in the solar system lies around the center point i.e. sun. These planets rotate around the sun in a circular path. Likewise in a heliocentric model it is believed that the sun is at the center of the universe and the planet earth along with all other planet move around it. Thus in both geocentric model and heliocentric model bodies in space move in circular orbits.

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
