To act as a catalyst in chemical reactions
Mitochondria and chloroplasts likely evolved from engulfed bacteria that once lived as independent organisms. ... Eukaryotic cells containing mitochondria then engulfed photosynthetic bacteria, which evolved to become specialized chloroplast organelles.
The answer is prokaryotes
Differential gene expression patterns allow one tissue to produce a hormone, and another to facilitate nutrient exchange. The same organ can serve both functions because it can synthesize different proteins.
<h3>Diferential gene expression</h3>
Gene expression refers to the differential process by which different genes are expressed (transcribed and then translated) in different cell types.
Gene expression enables different functions due to the production of different types of proteins which may have both enzymatic and structural functions.
A specialized cell type or organ can synthesize different proteins and also generate other molecules (either enzymes or structural proteins) due to the process of cell differentiation.

The forest ecosystem is characterized by a large amount of trees, animals, and water, while the desert has a limited amount of species.
A satellite in a polar orbit passes over both poles, but the earth rotates beneath it. The time taken for each orbit of the earth depends on the height of the satellite. If the satellite is in a circular orbit 260 kilometers above the surface it will have an orbital period of two hours.
