Gentian is a flowering plant that is native to Europe. The plant can have either red, yellow, or orange flowers. The flowers of these plants are pollinated by three species of bumblebees. Species 1 and species 2 visit orange and yellow flowers. Species 3 visits plants with only red flowers. Which is a likely advantage of having three different-colored varieties within a population of gentian plants?

A It allows the species to produce a large number of seeds after pollination.

B It allows the plant to attract pollinators other than bumblebees for pollination.

C It ensures that the species will survive even in the absence of a specific pollinator.

B It ensures that the flower can self-pollinate in the absence of pollinators.

The parents of a 9-year-old girl bring their daughter to the ed. for the last 12 hours, the child has suffered severe nausea and vomiting, as well as diarrhoea and abdominal cramps. further discussion with the child indicates that she suffers from blurred vision and headache. the parents originally were worried about bringing the child to the ed because they feared deportation since the family are illegal immigrants employed to pick strawberries on a nearby farm. on direct questionning, the parents admit that the child was assisting with spraying crops with pesticides the previous day. none of the family members was wearing any protecting clothing. her bp is 88/48 mmhg, pulse is 90/min, rr 33/min, temp 38 c. the child appears sweaty and confused. auscultation of the lungs reveals a diffuse wheeze bilaterally. pupils are miotic and the child has diffuse muscle weakness. which of the following interventions is the most appropriate treatment? - atropine- charcoal- glucagon- naloxone- exposure: consider organophosphate poisoning, which inhibits cholinesterase and results in accumulation of ach in both muscarinic and nicotinic sites. pralidoxime activates achatropine competes with ach only at muscarinic receptors, but will not reverse nicotinic effectscharcoal = gastric decontaminationglucagon = reverse beta-blocker overdosenaloxone = reverse effects of opioids
