WebEach of the following statements concerning the gram-positive cell wall is true EXCEPT. it protects the cell in a hypertonic environment. Bacteria are a commonly used organism for studies of genetic material in the research laboratory. The nucleic acids must first be isolated from the cells for these studies. WebThere are two important parts of a phospholipid: the head and the two tails. The head is a phosphate molecule that is attracted to water (hydrophilic).The two tails are made up of fatty acids (chains of carbon atoms) that aren’t compatible with, or repel, water (hydrophobic).The cell membrane is exposed to water mixed with electrolytes and other materials on the …
