Answer:
Paleozoic
Explanation:
It is during the late Paleozoic era, in the Carboniferous and Permian Periods, approximately 300 million years ago, that this transition occurred. During this period, there were higher global temperatures and tropical swamps dominated land on the Earth. This allowed amphibians to move farther inland. Later, synapsids and diapsids now dominated the land.

Answer:
Molecular clouds.
Explanation:
High-density and super-heated clouds of matter in a stellar nursery come together and form hot, nuclear balls of plasma called stars.
The correct answer is - magma intrusions.
The metamorphic rocks are rocks that basically have been either igneous or sedimentary, but have changed under certain circumstances. The initial igneous or sedimentary rocks, because of the geologic activities, often end up deep into the ground. As they get deep into the ground, they are exposed to higher temperatures and higher pressures, which over time change their structure, thus the creation of the metamorphic rocks. Also, the intrusion from the molten rocks known as magma, influence the creation and the type of the metamorphic rocks. This influence can be expected at places that are close to the plate boundaries, and where there's active volcanic activity in the region.
The members of the autosome pairs are truly homologous; that is, each member of a pair contains a full complement of the same genes (albeit, perhaps, in different allelic forms). The sex chromosomes, on the other hand, do not constitute a homologous pair
