Suppose that the resistance between the walls of a biological cell is 7.0 × 109 Ω. (a) What is the current when the potential di
DIA [1.3K]

Answer:

Explanation:

Using Ohm's law

V ( voltage) = I (current A) × Resistance R in ohms

R = 7.0 × 10⁹Ω

V = 80 mV = 80 / 1000 = 0.08 V

0.08 V = I × 7.0 × 10⁹Ω

a) I = 0.08 V / 7.0 × 10⁹Ω = 1.142857 × 10 ⁻¹¹ A

b) quantity of charge = I × t = 1.142857 × 10 ⁻¹¹ A × 0.85 s = 9.7142857 × 10⁻¹² C

number of Na⁺ ions ( q = +e) = 9.7142857 × 10⁻¹² C / 1.6 × 10⁻¹⁹ C = 60714285.714 Na⁺ ions

Assignment Summary For this assignment, you will model the structures of the cell and describe their functions. You will do this
iren [92.7K]

The model of the structures of the cell and and their functions is given in the image attached.

<h3>What are the cell structure and their functions?</h3>

Some explanation on structure of cells is given below:

The nucleus:

This is known to be the  key or major organelle that tends to sustain or hold the genetic information that is needed  for reproduction and cell growth as well as development.

Note that  all cell is known to be made up of one nucleus and also a kind of membrane-bound organelles that can be seen in the cytoplasm.

Mitochondria:

This is known to be a double membrane-bound organelle that is known to function by acting as the site for the energy transactions and it is made for the survival of all cell.

Therefore, The model of the structures of the cell and and their functions is given in the image attached.

leva [86]

Answer:

Isotonic

Explanation:

A solution that has same concentration os solutes inside and outside is called isotonic solution.As no concentration gradient is developed to induce the diffusion of large amount of water across the cell membrane rather water molecules freely diffuse in and outside the cell.So there is no gain and loss of water by the cell due to which the cell neither shrinks not swell
