When a genetic bottleneck happens, a species’ population ( blank ) . it’s unlikely that the species will have a high degree of ( blank ) , a population characteristic that provides a species with a greater chance of surviving changes to its environment. fill in the blanks

The right answers are : Declines (rapidly) and genetic diversity.

Phenomenon occurring when a population is greatly reduced over at least one generation. The low number of remaining breeders therefore transmits only a fraction of the initial genetic diversity to subsequent generations. This results in a genetic impoverishment of the population.

In conjunction with the founder effect, bottlenecks are one of the mechanisms of species evolution.

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
