An example of a population in which evolution could take place in a relatively short period of time could be pathogenic bacteria exposed to antibiotics.
Answer: Option A
<u>Explanation:</u>
Evolution if takes place within a short period of time say the next generation that is called as micro evolution. This is caused when a specific organism exposed in a different environment at once modifies its genes to suit the new environment. This phenomenon can be very well seen in the pathogenic bacteria which are exposed to antibiotics.
When an antibiotic is prescribed to bacteria initially it nullifies its effect by destroying it. When continuously exposed to a certain antibiotic some bacteria dies but there are few which becomes resistant to it and survives. This on the other hand multiplies producing a generation that can’t be touched by the antibiotic.

It too does Not require cellular energy. When molecules cannot move through a cell membrane passively, the Cell uses a process called_____________. This process uses_______________ found in the cells Membrane to pass particles and reach equilibrium.
The answer is A. The <span>eggs do not have a shell to prevent water loss.
Toad's eggs do not have a shell, like reptile eggs or bird eggs. Shell is important because it protects eggs from drying out if they are laid in the land. </span><span>Toads lay eggs in a jelly-like glycoprotein. </span><span>Thanks to glycoprotein around toad's eggs, contact with water is maintained all the time so that eggs don't die. </span>
