Answer:
1. Mitochondria
2. Chloroplast
3. the formation of eukaryotic cells
4. DNA
Explanation:
The theory of endosymbiosis was proposed by the Lynn Margulis in 1967 which suggested that the eukaryotic organelles like the mitochondria and chloroplast evolved when another prokaryotic cell engulfed the prokaryotic bacteria.
The mitochondria were formed when the chemosynthetic bacteria were engulfed by the bacteria and the engulfed bacteria formed a symbiotic relationship. Similarly, the chloroplast was originated in the same way when the photosynthetic bacteria were engulfed by another prokaryote.
The evidence which supports their ar:
1. The same size of the organelles to the bacteria
2. The presence of the circular DNA of the organelles like bacteria
3. The similarity in the 30s and 70s ribosomal subunits.
Answer:
This happens because of our immune system. Our immune system keep record of every attacking microbe. It contains two type of while blood cells firstly is T cell that respond quickly to the attacking microbe. While secondly B cells that recognize those specific cells and fights them off. In addition to that B cells clones itself as memory cells for that disease and will remains in your body for years
I think both Meg and Rachel applied the same force because the speed was the same
The translation is the process of protein synthesis where the information on RNA is expressed in the form of polypeptide chains. Transcription is the first step in gene expression. The translation is the second and final step of gene expression. Transcription occurs before translation
