Which of the following happened during the precambrian era? the first prokaryotic cells the first eukaryotic cells development of photosynthesis all of the above

D. All of the above

Precambrian time incorporates Earth's history from birth up to 590 million years back. That is, the Precambrian traverses 90% of Earth's presence. Fossilized microscopic organisms and blue-green growth demonstrate that crude life existed in any event 3,500 million years prior, and potentially prior.

However, it took another 2,100 million years for eukaryotic cells (plant and creature cells) to show up. These single-celled animals (protozoa) commanded the seas. Multi-cell creatures (spineless creatures) didn't advance until exceptionally late in Precambrian time, around 700 million years prior or 2,800 million years after life initially started on Earth.  

mendel's first law states that during the formation of reproductive cells , pairs of hereditary factors for a specific trait separate so that offspring receive one factor from each parent.
