Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color chage, formation of a precipitate, formation of a gas, odor change, temperature change.
When looking at a Neuromuscular Junction (NMJ), we know that neurotransmitters (NT) are released from the presynaptic cell and they then bind to the receptors that are located on the postsynaptic cell - this causes the effect of the NT being released.
So we are told that NT are still being released, however they are not having an effect. This would mean that they are probably being blocked by something - in this case, it seems that the neurotoxin is the culprit in the blocking of these receptors.
Therefore, if the NT cannot bind to the receptors on the postsynaptic cell, they are not going to have any effect, no matter how much NT is being released.
So the answer in this case is: The neurotoxin is most likely C) Blocking the receptors on the postsynaptic cell.
Answer:
d
Explanation:
<em>The correct answer would be increasing heart rate to compensate for low cardiac output.</em>
The negative feedback loop is the mechanism that is utilized in the maintenance of homeostasis. They work by opposing the processes that bring about a deviation away from setpoints, that is, the normal range of operation of physiological processes in the body.
<u>For example, when the heart rate goes below the setpoint, the negative feedback loop swings into action through the sensor, the control center, and the effector to return the heart rate to the normal operating range.</u>
Correct option: d
effect is from the modification of land surfaces. Waste heat generated by energy usage is a secondary contributor.
Answer:
False
Explanation:
Oxidation process occurring in liver rids bloodstream of not 32% of alcohol present.
Once the alcohol enters the body, 5 percent of it is excreted in the form of the urine and another 5 percent is eliminated from the body by exhaling and the rest of the alcohol is converted to acetic acid by oxidation.
Thus,
Oxidation process occurring in liver rids bloodstream of 90% of alcohol present.
