AlladinOne [14]2 years ago
6 0

The true statement about ligand gated sodium ion channels in neurons are open in response to chemical messenger and hyperpolarize the membrane.

<h3>What are ligand gated sodium ion channels?</h3>

Ligand gated sodium ion channels are the channels present in the neurons.  Ion moves through this channel inside the cell or outside the cell.

Thus, the correct option is a) Open in response to chemical messenger and depolarize the membrane.

In general it is best to conceptualize vectors as arrows in space, and then to make calculations with them using their component
JulijaS [17]

Answer:

The calculated vectors are:

\vec{A}-\vec{B}=(3,-5,-4)

\vec{B}-\vec{C}=(-5,4,0)

-\vec{A}+\vec{B}-\vec{C}=(-6,4,3)

3\vec{A}-2\vec{C}=(-3,-2,-11)

Explanation:

To operate with vectors, you sum or rest component to component. To multiply scalars with vectors, you distribute the scalar with each component of the vector. These are the following rules you must apply in these cases:

\vec{V}+\vec{W}=(V_1,V_2,V_3)+(W_1,W_2,W_3)=(V_1+W_1,V_2+W_2,V_3+W_3) (1)

\vec{V}-\vec{W}=(V_1,V_2,V_3)-(W_1,W_2,W_3)=(V_1-W_1,V_2-W_2,V_3-W_3) (2)

\alpha\cdot\vec{V}=\alpha\cdot(V_1,V_2,V_3)=(\alpha\cdot V_1,\alpha\cdot V_2,\alpha\cdot V_3) (3)

The operations in these cases are:

\vec{A}-\vec{B}=(1,0, -3)-(-2,5,1)=(3,-5,-4)

\vec{B}-\vec{C}=(-2,5,1)-(3,1,1)=(-5,4,0)

-\vec{A}+\vec{B}-\vec{C}=-(1,0, -3)+(-2,5,1)-(3,1,1)=(-6,4,3)

3\vec{A}-2\vec{C}=3(1,0, -3)-2(3,1,1)=(3,0, -9)-(6,2,2)=(-3,-2,-11)

If the current flowing through a circuit of constant resistance is doubled, the power dissipated by that circuit will
Anastasy [175]
Assuming that the voltage is constant, and the resistance was doubled, since I=V/R, the current through the circuit will be halved. As P=IV, with the same voltage and halved current, the power dissipated by the circuit will be halved
