A hypothetical bacterium swims among human intestinal contents until it finds a suitable location on the intestinal lining. It a
dheres to the intestinal lining using a feature that also protects it from phagocytes, bacteriophages, and dehydration. Fecal matter from a human in whose intestine this bacterium lives can spread the bacterium, even after being mixed with water and boiled. The bacterium is not susceptible to the penicillin family of antibiotics. It contains no plasmids and relatively little peptidoglycan. This bacterium's ability to survive in a human who is taking penicillin pills may be due to the presence of _____. 1. penicillin-resistance genes 2. a secretory system that removes penicillin from the cell 3. a Gram-positive cell wall 4. a Gram-negative cell wall 5. an endospore
An endospore is an extremely resistant dormant cell structure delivered by some bacterial species. On the off chance that you separate the term endospore, 'endo-' signifies 'inside' and '- spore' alludes to the 'torpid structure,' so the endospore is a structure shaped inside the cell. There are numerous instances of endospore-shaping microorganisms. The two most normal are Clostridium and Bacillus. In great conditions, these microorganisms are effectively developing and separating cells
On the off chance that a supplement, for example, carbon or nitrogen, turns out to be rare or if the populace turns out to be excessively thick, the microorganisms can get focused. They will enter a balance stage, which is their likeness endurance mode. The microorganisms can make due in the balance until better development conditions return
If the water molecule was linear instead of bent, water
would no longer produce hydrogen bonds. It will lose its polar properties and
nearly all of its properties will change such as boiling point, water tension
and solubility. It would be closer to gas, rather than liquid.
Glycerol molecule Two fatty acids A phosphate group The negatively charged polar head which is hydrophilic The fatty acid chains are uncharged nonpolar tails that are hydrophobic
