The process responsible for the evolution of mitochondria and chloroplasts in eukaryotes is Symbiogenesis or endosymbiotic theory.
This theory states<span> that </span>mitochondria and chloroplasts originated from bacteria entering a eukaryotic cell to form a symbiotic relationship.
Among the pieces of evidence supporting symbiogenesis are that new mitochondria and plastids are formed only through binary fission and the striking similarities between bacteria and these organelles<span><span /> (mitochondria and chloroplasts). Similarities include 1) They have their own DNA, which is separate from the DNA found in the nucleus of the cell. and 2) both organelles use their DNA to produce many proteins and enzymes required for their function</span>
The pancreas is connected directly into the small intestines and gallbladder.
Enzymes that are produced by the pancreas are secreted directly into the small
<span>intestine.</span>
An example of macroevolution is the evolution of a new species. One mechanism that drives evolution is natural selection, which is a process that increases the frequency of advantageous alleles in a population. Natural selection results in organisms that are more likely to survive and reproduce.
because it comes from the everyday activities of many different people, such as fertilizing a lawn, using a pesticide, or constructing a road or building.
