It’s due to stem cells. The genes in dna turn on and off to give a cell a specific job, so stem cells can be “programmed” as any cell the body needs. (Muscle cell, skin cell, etc)
<span>Prokaryotes have magnetite-containing structures, nucleoid (their version of a nucleus), fimbriae.
Animals have lysosomes.
Plant cells have chloroplasts (make the plant cells green, produce energy for plants), photosynthetic membranes (produce energy for plants), cell well.
Flagella can be found in prokaryotes and animal cells but for a simpler biology class, I would put it with prokaryotes.</span>
Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.
The prokaryotic cells that built stromatollites are classified as <span>cyanobacteria.</span>
