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:
Body water homeostasis is regulated mainly through ingested fluids, which, in turn, depends on thirst. Thirst is a sensation created by the hypothalamus, the thirst center of the human body.
Explanation:
Answer:
The correct answer is - option C.
Explanation:
The represented diagram shows the process of photosynthesis and how carbon dioxide and water are converted to carbohydrates and oxygen with help of light energy.
In this representation, the carbon dioxide comes from the atmosphere and transfer carbon to the cells of the plant or organism (biosphere) performing the photosynthesis in form of carbohydrates. Therefore it is a representation of the role of photosynthesis in transferring the carbon from atmosphere to the biosphere.
