Three lines of evidence that support the endosymbiotic theory:
1. The presence of membrane- Organelles like mitochondria and plastids have their own cell membranes, just like a prokaryotic cell does,
2. The presence of DNA- Each of these organelles have its own DNA genome, like a bacteria's genome, but much smaller.
<span>3. Reproduction (division)-Multiplication of the organelles occurs just like in bacteria, by division.</span>
All three scientists would most effectively demonstrate their concepts by using models.
Models are often used in science to provide a simplified visual representation of a certain phenomenon, making it easier to observe, understand and predict the possible future outcomes or effects of the demonstrated phenomena.
Answer:
Autotroph or producers
Explanation:
An organism that produces its own food is a autotroph
Only a fraction of the genes in a cell are expressed at any one time. The variety of gene expression profiles characteristic of different cell types arise because these cells have distinct sets of transcription regulators
