(1 pt) which of the following is a behavioral adaptation of the venus fly trap?
a. leaves that close when touched
b. leaves that perform photosynthesis
c. roots that the plant uses to obtain water
d. flowers to attract pollinators

a. leaves that close when touched.

Explanation:

Venus flytrap is an insectivorous plant. Its scientific name is Dionaea muscipula. It has a specialised system by which it traps and kills insects. Venus flytrap is an autotroph (makes its own food through photosynthesis), but it absorbs nitrogen and phosphorous from insects because the soil in which it grows lack these elements. It has steel-trap shaped leaves which secrete sweet-smelling nectar and when insects land on its leaves for the nectar insects get trapped.

explanation:

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.
