Explanation:
<u>the Paleozoic Era </u>
The Precambrian era describes a period of time that pre-dates Cambrian. This time typically references the entire period of the history of earth before the formation of rocks containing identifiable fossils occurred. It covers the majority of Earth’s history and is divided into the Hadean, Archean and the Proterozoic era.
Just before the Cambrian eruption, in the Paleozoic Era the environment was oxygenated, culminating in an explosion of new life in the Proteozoic Eon (2500-541 million years ago) in the form of primitive blue-green algae named cyanobacteria and oxygen based species. Multicellular species followed later, along with structure at higher levels, and complex life. Oxygen levels grew gradually over this period of time, from low levels.

The light will enter they eye and it will be refracted as it
passes through the cornea. It will then pass the pupil which is controlled by
iris and will be further refracted by the lens. The cornea and lens together
will form a compound lens in order to project images which are inverted into the
retina.
Speed. This is more of a physics question.
Answer:
is a principle of geology that states that the geologic feature which cuts another is the younger of the two features. It is a relative dating technique in geology.
Most of them seem to be a safe bet.
I don’t think someone would be too fussed about a diagram of a chloroplast.
