Answer: W = 6.4x10⁻²¹J

Explanation: <u>Work</u> is the energy transferred to or from an object due to the application of a force along a displacement.

The ion Na is gaining energy to move from a lower potential to a higher one.

For this to happen, the work done is calculated as

W=q.\Delta V

in which

W is work in Joules (J)

q is charge in Coulomb (C)

\Delta V is potential difference in Volts (V)

The ion Na has one positive charge. In coulombs, the charge is

q = 1.6x10⁻¹⁹C

The potential difference in Volts is

\Delta V = 40x10⁻³ or 4x10⁻²V

Calculating

W=q.\Delta V

W = 1.6x10⁻¹⁹. 4x10⁻²

W = 6.4 x 10⁻²¹ J

The work done to move an ion of sodium from the exterior to the interior is 6.4 x 10⁻²¹ J.

nirvana33 [79]

The term that would best define the fish added to the pond is introduced species.

<h3>What is introduction of a species?</h3>

Adaptation to the conditions of the place in which it was inserted, the absence of predators and degradation are the main factors that lead an exotic species to become invasive, competing with native species for resources and causing a great impact on the community.

In this case, the introduced species are exotic species which has arrived there by human activity, may even be harmful to the entire ecosystem because they can break the delicate equilibrium of the ecosystem.
