Answer:
Negative feedback.
Explanation:
Body's homeostasis is maintained by two feedback mechanism known as positive feedback and negative feedback. Most processes in our body is controlled by the negative feedback mechanism.
The negative feedback mechanism in which the final product of the reaction decreases the further secretion of that product. In case of the body temperature rise, brain canter decreases the body temperature is controlled by negative feedback. The high level of the substance decreases its further secretion in case of maintenance of body temperature.
Thus, the correct answer is option (c).
Answer:
14.8% of H2O2
Explanation:
Based on the redox reaction of H2O2/MnO4- is:
2MnO4- + 5H2O2 + 6H+ ⇄ 2Mn2+ + 5O2 + 8H2O
<em>2 moles of KMnO4 react with 5 moles of H2O2</em>
<em />
To solve this question we need to find the moles of KMnO4 until reach the endpoint. Using the balanced reaction, we can find the moles of H2O2 that must be converted to grams using its molar mass -Molar mass H2O2: 34.015g/mol-:
<em>Moles KMnO4:</em>
0.0297L * (1.4686eq/L) = 0.04362eq MnO4- * (1mol / 5eq) = 0.008723 moles MnO4-
<em>Moles H2O2:</em>
0.008723 moles MnO4- * (5mol H2O2 / 2mol MnO4-) = 0.02181 moles H2O2
<em>Mass H2O2:</em>
0.02181 moles H2O2 * (34.015g/mol) = 0.7418g H2O2
<em>%:</em>
0.7418g H2O2 / 5.0mL * 100
<h3>14.8% of H2O2</h3>
Agoraphobia is the fear of being out in the open. People with Agoraphobia are scared of leaving home, crowded places and places that escape would be difficult.
Answer: B). Managing the air way.
Explanation:
In the case of the facial trauma, the ventilation and breathing becomes labored for the victim. Hence stabilization of breathing is necessary to provide life to the victim. The air passage should be manage that is if patient is not able to respire through nose mouth opening should be manage to save life.
In the given condition the face has been affected by the collision thus air way should be managed.
Answer:
The kidneys regulate circulatory volume by controlling sodium and water balance, thus maintaining extracellular fluid volume (ECFV) homeostasis. Simply put, an increase in sodium and water consumption leads to an increase in ECFV, which in turn increases blood volume
