Mitosis
Mitosis, throughout the division of the cell, is characterized by the presence of two fundamental components. Normally, mitotic figures are the chromatic axis and the achromatic axis.

HDD vs. SSD: Key Differences
A traditional hard disk drive (HDD) is composed of individual disks, or platters, with read/write heads on actuator arms controlled by a servo motor, all contained in a sealed case that prevents contamination by outside air.

They were originally developed to transition vacuum tube-based technologies to semiconductor technologies. However, they are more

What is Economic Activity?
People have many needs: food, clothing, housing, medical care, etc. We call economic activity any process by which we obtain the products and services that meet those needs. Economic activities cover three stages: the production of what we need, distribution, and consumption.

The arrival of democracy in Portugal produced significant legislative and economic changes in Portuguese society, bringing about social change.
