Normal polarity
Explanation:
Earth's magnetic field used to be twice as strong 1.5 billion years ago as it is today and Earth's temperature other than what the geologists see from the 'normal' pattern. It has been noticed that some volcanic rocks were magnetized in opposite direction to the direction of the local Earth's field. It is clear that the Earth has experienced the normal polarity 1.5 years ago but at that time, the Earth's polarity was poorly understood.
The plant belongs to the group Angiosperm. Vascular plants with seeds could be cycads, Gingko, conifers, or angiosperms. Among those groups, only angiosperms have flowers.
The plant they found have colored, scented flowers which suggests that it could be pollinated by insects or birds. Colored flowers attract birds and insects. Color serves as a guiding mark. Talking of scent, it does not attract bird, but attracts insects. It also serves as the guiding mark.
The Golgi apparatus is a membranous organelle that resembles a stack of flattened sacs with bulbous ends and associated vesicles.
<h3>What is the Golgi apparatus?</h3>
The Golgi apparatus is an organelle composed of many flattened membranes that serve to process and transport different macromolecules such as lipids in the endomembrane system.
In conclusion, the Golgi apparatus is a membranous organelle that resembles a stack of flattened sacs with bulbous ends and associated vesicles.

Answer:
In multicellular organisms, the mechanism most directly responsible for directing development and maintaining homeostasis is gene "regulation"
Explanation:
Even though the organs present throughout the body helps in maintaining the homeostasis, But the systems like endocrine system and nervous system plays important role in sustaining and regulating it. The gene regulation is the increase and decrease of the specific gene products. Gene regulation can also be understood as the regulating process which helps in controlling ability of the cell to the environmental changes or can say the adaptability of the cell to changing environment done by gene regulation.
