Answer: Option B. "False"
Explanation:
Nephron can be defined as the functional unit of the kidney.
Descending limb and ascending limb are the combinly called loop of nephron or henle and are the part of renal tubule in the nephron.
Descending limbs and ascending limbs have different permeabilities to water and salt that causes high osmolarity in the Medulla.
The thin descending limb is having high permeability to water as they have low permeability to ions and urea while the thick ascending limb has impermeablity to water as there is active reabsorption of ions.
Hence, the correct option is B.
Answer:
The correct answer will be:
1. Acetylcholine binds to receptors on the motor end plate
2. Chemically-regulated ion channels open, causing depolarization
3 End plate potentials trigger action potential(s).
4. Transverse tubules convey potentials into the interior of the cell
5. Ca++ is released from the sarcoplasmic reticulum
6. Ca++ binds to troponin, pulling on tropomyosin
7. Binding sites on actin are uncovered, allowing myosin to bind and carry out power strokes
8. Force increases.
9. Ca++ is pumped (re-sequestered) into the sarcoplasmic reticulum
10. Force decreases.
Explanation:
The muscle contraction is a highly controlled mechanism which begins at the neuromuscular junction with the release of the acetylcholine neurotransmitter. This neurotransmitter causes the depolarization of the membrane by binding to the receptors of the motor end plate which generates an action potential. This action potential is transmitted via T-tubules from sarcolemma to the sarcoplasmic reticulum.
The sarcoplasmic reticulum releases calcium ions which binds to the troponin protein. This troponin removes the protein tropomyosin from the actin causing the rotation of the tropomyosin exposing the binding sites for myosin. The myosin binds to the actin using energy from the ATP which pulls the actin causing contraction. Another ATP binds the myosin head which weakens the bond between myosin and actin which releases the myosin which decreases the force between them decreases and the muscles relax.
Answer:
But while a stethoscope and other at-home devices make this possible, hearing the faint sound of a baby's heartbeat isn't always possible. One of the best ways to hear the heartbeat is during a prenatal appointment when your OB-GYN uses an ultrasound or fetal Doppler
The nurse is to administer a potassium supplement to the client and does not check the potassium level prior to administering the medication and later finds that the potassium level was at a critical high which means that the nonmaleficence principle was violated which is denoted as option B.
<h3>What is Nonmaleficence? </h3>
This refers to the duty of a professional such as healthcare workers in ensuring that there is no harm done to the client or patient.
In this scenario, negligence caused the nurse to administer a medication which had a critically high amount of potassium which is harmful to the body.
This is therefore the reason why nonmaleficence was chosen as the correct choice.
