Competition is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource (such as food, water, and territory) used by both can be a factor.
True.
Albumin proteins bind some of the calcium, and changes in pH can affect the true reading of serum calcium.

Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Strands of hair originate in an epidermal penetration of the dermis called the hair follicle. The hair shaft is the part of the hair not anchored to the follicle, and much of this is exposed at the skin’s surface. The rest of the hair, which is anchored in the follicle, lies below the surface of the skin and is referred to as the hair root. The hair root ends deep in the dermis at the hair bulb, and includes a layer of mitotically active basal cells called the hair matrix. The hair bulb surrounds the hair papilla, which is made of connective tissue and contains blood capillaries and nerve endings from the dermis.
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.
