Answer:
Minerals can form in all geological environments, which allows them to have a wide range of chemical and physical conditions. Two forms of this are temperature and pressure. There are 4 main categories of mineral formations. Igneous is where the minerals crystalize from a melt. Sedimentary is where the raw materials of the mineral are particles from other rocks that have suffered from erosion and weathering. Metamorphic is where new minerals are created from earlier ones owing to the effects of change. Most of the time it's from increasing temperature and/or pressure. Hydrothermal is where the minerals are chemically precipitated from hot solutions in the earth.
Answer:
Eukaryotes
Explanation:
Eukaryotic cells have membrane bound organelles.
Prokaryotic cells do NOT have membrane bound organelles.
So, a Eukaryotic cell has structures such as a nucleus, mitochondria, a golgi complex, etc. This provides the cells with distinct stuctures that have distinct functions.
consider the expression of a protein (protein synthesis.) Transcription of the DNA into RNA happens within the nucleus. The mRNA is sent from the nucleus to the cyctoplasm, where translation occurs at either the rough endoplasmic reticulum or the free floating ribosomes.
A prokaryotic cell has all of its machinery floating around inside its cytoplasm with no separation. In these cells, transcription and translation both occur in the cytoplasm. In fact, translation often begins before transcription is finished...
Hey!
Hope this helps...

A user mentioned in the comments of one of the answers deleted: "its B" < The user (<span>lolbae0806) had mentioned this...</span>
So I believe the correct answer is:
B.) More oxygen gas became present in the atmosphere.
