Question

One plant opens its flower during the day, whereas a nearby plant only opens its flowers at night.

Ans : Temporal isolation - Prezygotic barrier

Reason :  Temporal isolation means isolated in time, so this is a mechanism that prevents species from mating because they breed at different times. These differences can be time of day, season, or even different years. It is a prezygotic barrier of reproduction.

Question

If a person takes an antibiotic for a bacterial infection, this can reduce the amount of bacteria in their normal microbiota and allow yeast in their genitourinary tract to flourish, which could result in yeast infection. This is an example of

Ans : Option 4

$\odot$ Endosymbiosis

Reason : A symbiotic relationship where one organism lives inside the other is known as endosymbiosis. Yeast is a Fungi that are multicellular, eukaryotic organisms, while bacteria are single-celled prokaryotes. In most cases, bacteria provide the fungus with some form of metabolic benefit while the fungus often provides a suitable living environment. The antibiotic leading to the death of bacteria allow yeast to use the nutrients more and hence they flourish and as a result cause yeast infection.
