Imagine that a researcher discovers two new similar species of bats in the same geographic area. Amazingly, one of these species
preys upon insects during the day. The other species, as one would expect, is nocturnal and only feeds during the night. These two bat species would be considered:
A form of prezygotic reproductive barrier is temporal separation or temporal Isolation. Temporal isolation stands for 'isolated in time,' that is to say, species mates at different times probably the time of the day, season or different years, even though they are closely related or live in the same habitat.
Another example is the American toad and the Fowler's toad. Both are closely related species with distinct copulation peridods. The American toad copulates during early summer and the other at lat summer.
A single test won't put the definitive diagnosis of diabetes. This diagnosis is put on 3 conseccutive measurements and they all have to be more that 125.
The pH of stomach secretion is low. This means it is acidic. Too much production can corrode the stomach wall. Therefore in such a situation drinking a basic solution with a higher pH neutralizes some of the stomach acidic secretions hence relieving the effect;
