Answer:
caused acetylcholine to be continuously released by the motor neurons.
Explanation:
The venom of black widow spider is neurotoxic and contains α-latrotoxin. This toxin binds to the surface receptors of neurosecretory PC12 cells and vertebrate synapses and activates the release of the neurotransmitter acetylcholine.
Acetylcholine is the neurotransmitter which plays important role in muscle contraction so the toxin allow the continuous release of the neurotransmitter which cause contraction of smooth muscle in airways and other muscle in the body and cause breathing difficulties and muscle spasms.

One millivolt of electricity, when thrown into the EKG machine, will deflect the stylus 10mm.
<h3>What does an EKG machine do?</h3>
To check for various cardiac diseases, an electrocardiogram (ECG or EKG) measures the electrical signal from the heart. Electrodes are positioned on the chest to capture the electrical impulses that drive the heartbeat. The signals are displayed as waves on a computer monitor or printer that is connected. EKG provides details about your heart's rhythm and pace, as well as whether your heart has enlarged owing to hypertension or has signs of a past heart attack (myocardial infarction).
The EKG is written down on regular paper that is moving at a speed of 25 mm per second. The paper is cut into huge squares that are each 5 mm wide, or 0.2 s, in size. On the EKG, a wandering baseline artifact appears as a sluggish, undulating baseline. It may be brought on by the patient's breathing or other movements.
