These gymnosperms soon became the dominant plants. The Mesozoic is sometimes called the Age of cycads.
But their success was only short-lived. During the mid to late Mesozoic, the first flowering plants or angiosperms appeared.
The mesozoic is <span>Triassic</span>
The question is incomplete as it does not have the options which have been provided in the attached file.
Explanation:
1. Dura mater: the dura mater is the most superficial layer which is characterized by the folds. The dura mater forms the walls between the hemisphere of the brain that is between right and left halves of the cerebellum. The structure present in the dura mater is tentorium cerebelli and super sagittal sinus.
2. Pia mater: the deepest layer present which is adhered to the tissues of the brain. The cortical gyri blood vesicle are superficial to the pia mater.
3. Arachnoid mater: the middle layer which is characterised by transparent and gelatin-like appearance.

Answer:
Yes
Explanation:
A phase change does not change the chemical make-up of a substance. Phase changes are typically temperature dependent, and change only the movement and physical arrangement of the atoms and molecules in the substance. Water, for example, is composed of two hydrogen atoms attached to an oxygen atom by covalent bonds. That stays the same whether the water is solid (ice), liquid (water), or gas (steam). The chemical structure of water does not change as it goes through the different faces. It's still water. What does change is the speed at which the molecules move and how far apart they are as a result. Water vapor consists of molecules moving quickly and at random. As temperature drops, water molecules slow down. Since water is slightly polar, hydrogen bonds form between the molecules bringing them closer together.
