1. Adaptações Celulares
As células se adaptam a estímulos ou estresses para manterem sua função, mas, se falham, sofrem lesão.
* Hiperplasia: Aumento do número de células. É um processo de divisão celular que pode ser fisiológico (hormonal, como nas mamas e útero durante a gravidez) ou compensatório (regeneração, como na hepatectomia parcial do fígado). Pode ser também patológica, como em queloides ou na hiperplasia prostática benigna.
* Hipertrofia: Aumento do tamanho das
Terra nullius is a Latin term meaning "land belonging to no one," which was a legal principle used by European colonisers to claim sovereignty over inhabited territories, including Australia. Despite knowing there were indigenous people living in Australia, Britisher claimed Australia using the concept of Terra Tullius as justification as they felt as though the Aboriginal were not using he land ( lack of building, roads and infrastructure)

Plant cell expansion is a turgor-driven process, where water uptake into the vacuole generates internal pressure. For the cell to enlarge, its cell wall must be extensible. This is tightly regulated by hormones especially auxin, the primary being Indole-3-acetic acid (IAA).
IAA promotes cell elongation particularly in young, growing tissues (e.g., coleoptiles, root tips) by modifying the mechanical properties of the cell wall.

Role of Indole-3-Acetic Acid (IAA) in Plant Cell Wall Expansion
Plant cell expansion is a turgor-driven increase in cell size that is constrained by the mechanical properties of the cell wall. Among phytohormones, Indole-3-Acetic Acid (IAA), the principal auxin, plays a central role in promoting cell elongation by modulating cell wall extensibility. The classical mechanism underlying this process is the acid growth hypothesis, which posits that IAA activates plasma membrane H⁺-ATPases, pumping

Sappho and Her Poetry – To an Army Wife in Sardis
Importance: Influenced Catullus, Horace, other poets/critics; unlike Homer, poetry is personal, direct, not long oral epic.
Context: Early Greek poetry was oral; Sappho lived when women could claim authorship; poetry shows folk-song influence of Lesbos, simple/direct; only 2 complete poems survive, rest fragments.
Lyric Poetry: Lyric = personal, direct, less formal; Sappho = leader/teacher of aristocratic women; wrote about women, family, friends,
