<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>
Our genes can be affected by the environment and change the way our traits are displayed, called the phenotype. However, changes in phenotype have an underlying genotypic source. Epigenetics or epigenetic changes are changes in the way traits are expressed as an effect of the environment (i.e. food we ate, chemicals in the body, environmental stresses), without changes in the DNA. Simply put, in epigenetics, some parts of the DNA are turned on or off in response to environmental conditions.
I think its Uracil replaces thymine on rna
Hope this helps
