According to the dichotomous key, in what way(s) is the house sparrow similar to the cobra? A) Both are autotrophic and live on
vitfil [10]

The correct answer is the option (D) Both are not a mammal, are multicellular, and are heterotrophic.

Keys in biology are used to identify the different species based on the easily identifiable features of the organism. A dichotomous key consists of a series of questions on features like habitat, mode of nutrition, class to which they belong and other features, with each question having two answers describing the characteristic features of an organism. The series of questions begin with a broader characteristic feature becoming narrow gradually and helping in the identification of the organism.

Both the house sparrow and a cobra cannot synthesize their own food and depend on other organisms for food. Hence they are heterotrophic. They are multicellular in nature. A cobra belongs to the class Repltiles and a house sparrow belongs to the class Aves. Thus, a house sparrow and a cobra are similar to each other in being multicellular, heterotrophic and not belonging to the class mammals.

Suppose you are recording a neuron’s resting membrane potential. If you added more KCl to the external medium, what would happen
Talja [164]

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.
