Exam: GRE (Verbal)

Definition: A small, cylindrical structure found in cells that helps in cell division by forming the spindle apparatus.

Example: During cell division, the centrioles play a crucial role in organizing the microtubules.

Definition: Describing something that moves or is directed toward a center or axis, often used in physics and biology.

Example: The centripetal force keeps the planets in orbit around the sun.

Definition: In a manner that moves or directs towards a center or axis.

Example: The planets revolve around the sun centripetally, maintaining their orbits due to gravitational pull.

Definition: A political belief that seeks a middle ground between extreme views, avoiding both far-right and far-left positions.

Example: Centrism is often seen as a way to appeal to a broader range of voters.

Definition: Describing a political view that is moderate and not extreme, often balancing between left and right ideologies.

Example: The centrist candidate appealed to voters from both major parties.

Definition: A person who holds moderate political views, often positioned between the extremes of left and right.

Example: The centrist candidate appealed to voters from both sides of the political spectrum.

Definition: A point that represents the average position of all the points in a shape or object, often used in geometry and physics to find the center of mass.

Example: In a triangle, the centroid is the point where all three medians intersect.

Definition: The part of a chromosome that is the narrowest point, where the spindle fibers attach during cell division.

Example: During cell division, the spindle fibers connect to the centromere to help separate the chromosomes.

Definition: Relating to the part of a chromosome that links sister chromatids and is essential for proper cell division.

Example: The centromeric region of the chromosome is crucial for the movement of genetic material during cell division.

Definition: A small part of a cell near the nucleus that helps organize structures called microtubules, which are important for cell shape and movement.

Example: The centrosome plays a crucial role in cell division by organizing the microtubules that separate chromosomes.

Definition: Describing something that has a center point where it is symmetrical on all sides.

Example: The design of the building is centrosymmetric, making it visually balanced from every angle.
