Answer:
Answer B. Endosymbiosis
Explanation:
Early protists were first eukaryotic organisms and had several membrane bound organelles. The anaerobic protists evolved by acquiring purple bacteria. The purple bacteria have the ability to carry out aerobic cellular respiration. The endosymbiont transformed into mitochondria in due course of evolution. Similarly, the photosynthesizing protists were evolved by endosymbiosis of cyanobacteria which in turn was transformed into chloroplast during further evolution.
<h2>Tropomyosin</h2>
Explanation:
This protein is most likely: Tropomyosin.
Sacromere is the structural unit of myofibrils i.e. the fibres of the muscles.
Tropomyosin is the muscle protein that function in contraction of muscle filaments.They are arranged laterally along the myofilament. When the researcher is observing the sacromere, she is observing the muscle fibre. So, the protein that lines the periphery along the thin filament is more likely to be tropomysin.
Answer-
All the bonds are hydrogen bonds and this bond is strong
