Answer:
addition to the external medium.
Genearlly, potassium is an intracellualr ion, therefore there is higher concentration of potasium ions with its positive charges inside than outside.In addition potassium ion has many leaking potassium channels in the cell membrane,which permit K+ to escape down the gradient to the extracellular medium.
Therefore when KCl is added to the external medium of a resting neuron, the concentration of external K+ increase than intracellular medium, preventing K+ from diffusing out to the external medium, retaining their positive charges, therefore favouring depolarization of the neuron.This decreases the RMP, leading to depolarization.
If the KCl is reduced, less k+ are available outside compare to the inner medium.Therefore electrochemical gradients is sets up for leaking of K+out of the intracellular layers, caring the positive charges along, leaving the inside more negative (together with the negative charges of the anions of the intracellular layer). This is reversal of charges.And it increases the RMP.
Explanation:
The answer is Convergence of images behind the Retina
Convex lens converges light to a principal focus. The thickness of the lens determines the focal length (distance between the center of the lens and the principal focal point). Therefore, by evaluating the thickness of the convex lens, farsightedness, (an eye defect of convergence of images behind the retina) can be corrected by enabling images in the eye to form behind the retina.
Answer;
ATP
ATP is the essential molecule for the detachment.
Explanation;
-Muscles use actin and myosin molecules to convert the energy of ATP into force.
-During the power stroke, the phosphate generated in the previous contraction cycle is released which results in the myosin head pivoting toward the center of the sarcomere, after which the attached ADP and phosphate group are released.
-A new molecule of ATP attaches to the myosin head, causing the cross-bridge to detach.
-The myosin head hydrolyzes ATP to ADP and phosphate, which returns the myosin to the cocked position.
