During action potential, positively charged ________ ions move inside the cell.
Tems11 [23]

During action potential, positively charged  sodium ions move inside the cell.

So option D is correct one.

The sodium ion moves inside the cell during a action potential. The stage of action potential is called depolarization . This open voltage gated sodium channel.

Action potentials ( those electrical impulse that send signals around body )  is nothing but more than temporary shift ( from negative to positive ) in the neuron's membrane potential caused by ions suddenly flowing in and out of the neuron.

It consists of phases:

  • Depolarization
  • overshoot
  • repolarization

An active potential propagates along the cell membrane of an axon until  it reaches the terminal button.

A student has a piece of aluminum metal what is the most reasonable assumption a student can make about the metal
Gala2k [10]

Answer:

<h2>- It could be stretched into a thin wire.</h2>

Explanation:

As per the question, the most rational claim that the student can make about the aluminum metal is that 'it could be stretched into a thin wire' without breaking which shows its ductility. It is one of the most significant characteristics of a metal. Metals can conduct electricity in any state and not only when melted. Thus, option A is wrong. Options C and D are incorrect as metals neither have the same shape always nor do they break on hitting with a hammer. Therefore, <u>option E</u> is the correct answer.

Can someone help please I will give Brainlyiest
kotykmax [81]

Answer:

See Explanation

Explanation:

moles of NH₃ = 11.9g/17.03 g/mol = 0.699 mole

moles of CN₂OH₄ = 1/2(0.699) mole =0.349 mole

Theoretical yield of CN₂OH₄ = (0.349 mole)(60 g/mole) = 20.963 grams

%Yield = Actual Yield/Theoretical Yield x 100%

= 18.5g/20.963g x 100% = 88.25%
