A fire kills the 95% of the salamanders in a forest. Prior to the fire, the salamander population had a lot of different colors (from light yellow to dark green), but the majority of individuals were a medium shade of green and blended quite well with the vegetation. After the fire, the few remaining individuals were all light in color. A decade later, the population has increased back to a similar size as the pre-fire population, but there are still only light-colored individuals. What happened here

All of the characters are present in a bacteria.

Explanation:

i)Bacterial cell wall is composed of petidoglycans which is made up of sugar and amino acid molecules that helps in protecting the bacteria from different antibiotics like penicillin etc.

ii)Bacteria lack many cell organelles that are found in eukaryotic organisms like nucleus,mitochondria, golgi body, ER,chloroplast etc.

iii)Bacterial plasma membrane mainly formed by amphiphilic lipids which contain glycerol, phospholipids, that are composed of two fatty acids and a  phosphate group with variable head.

iv)Bacteria require proper environment like food,moisture,temperature for their growth and development.The ideal temperature is 40-122°C
