Biology
1 answer:
kenny6666 [7]4 years ago
8 0

Answer:

The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. In this theory, the first eukaryotic cell was probably an amoeba-like cell that got nutrients by phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosomes. Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the organism and developed a symbiotic relationship. Mitochondria formed when bacteria capable of aerobic respiration were ingested; chloroplasts formed when photosynthetic bacteria were ingested. They eventually lost their cell wall and much of their DNA because they were not of benefit within the host cell. Mitochondria and chloroplasts cannot grow outside their host cell.

mel-nik [20]
The correct answer is to "dilute with milk and water". The patient should not be induced to vomit to prevent aspiration as this can lead to another condition which is aspiration pneumonia. The patient should be given either a glass of milk or a glass of water for ingestion of petroleum jelly.
