Answer:
The muscle's insertion
Explanation:
The moveable end of the muscle that attaches to the bone being pulled is called the muscle's insertion, and the end of the muscle attaches to a fixed (stabilized) bone is called the origin.
Answer: D. Contractility of the heart muscle refers to the force of contraction that this muscle can exert.
Explanation:
The myocardial contractility is ability of the heart muscles to contract. This is achieved by the forces which develop between the contracting muscles caused by the filaments of actin and myosin.
The degree of binding of the muscle filaments dependents upon the calcium ion concentration. These actions are controlled in vivo by the sympathetic nervous system. It is driven by the release of the catecholamine, which is a process which determines the calcium ion concentration inside the cytosol of the muscles of the heart.
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>
The urine volume would enhance if ADH was not added to the collecting duct. This is because the ADH works on the collecting ducts where the increase permeability for water is improved, so less water is perspired into the urine, so urine evolves more concentrated.
<h3>What happens to urine volume when ADH advances?</h3>
- ADH improves the permeability to water of the distal serpentine tubule and collecting duct, which is normally impervious to water. This effect causes heightened water reabsorption and retention and reduces the volume of urine produced comparable to its ion content.
- In SIADH, the body is unable to subdue the secretion of ADH, conducting to insufficient water excretion and reduced urine output. Normally, when water is ingested, serum tonicity and osmolality reduction, and ADH are quelled, resulting in an output of dilute (less concentrated) urine.
- A hormone that allows blood vessels narrow and helps the kidneys control the portion of water and salt in the body. This enables the control of blood pressure and the quantity of urine that is made. Antidiuretic hormone is made by a portion of the brain called the hypothalamus and is perspired into the blood by the pituitary gland.

Answer:
expectations
Explanation:
Kamea has always had a bad back. Lately she has been experiencing a great deal of pain in her lower back. Her experience of pain is in part the result of her EXPECTATIONS about pain.
