Base your answers to the questions below on the following information:
Using the patch clamp technique, a researcher measures a single channel in a membrane. The receptor channel passes 3 pA (picoamperes) of ionic current over a period of 8 msec at -60 mV; 1 pA = 10 -12 ampere. Based on your knowledge of nerve transmission, this movement of ions will A) stimulate a change in a postsynaptic membrane. B) not stimulate a change in a postsynaptic membrane. C) stimulate a change in a postsynaptic membrane if three channel events are combined. D) stimulate a change in a postsynaptic membrane if 50 channel events are combined. E) generate a current resulting in membrane depolarization.

Some genes tend to be inherited together. d. Environmental factors may influence gene expression. e. There are two sets of chromosomes, one maternal, one paternal, in diploid forms.

One of the possible concerns about genetically modified foods is that they might kill organisms that we don't want to kill. Which statement is an example of this phenomenon?
A) Bears eating genetically modified corn may be poisoned by the Bt gene introduced to the corn to act as a pesticide. B) The pollen from plants containing insect-killing Bt genes can be blown onto other plants. Insects that we don't want to kill, such as monarch butterflies, may be killed by such pollen. C) Genetically modified super-sized salmon have been known to kill the bald eagles that generally feed on them. D) In the Irish Potato Famine, more than one million people died as a result of the lack of genetic diversity in the potato crop. E) Thousands of people went into anaphylactic shock after consuming modified soybeans that contained a gene from Brazil nuts.
