Which of the following provides the best analogy for an electron in an atomic orbital?

a. a cow grazing in a pasture
b. a bird resting on a tree branch
c. an ant crawling on the surface of a leaf
d. a bee hovering around a bee hive

The correct answer is D. A bee hovering around a beehive

Explanation:

Electrons are negatively charged, and they orbit the nucleus of atoms, where protons (positively charged) and neutrons (neutrally charged) are. Besides this, the difference in electric charge makes electrons to constantly orbit the nucleus, although these can still change their orbital (zone in which the electron orbits).

In this context, the best analogy for an electron is a bee hovering around a beehive because as electrons bees constantly orbit the beehive that represents the nucleus. Also, they can change their orbit or movement but will still orbit the beehive, and there is an attractive force between the bee and the beehive as it occurs between the electron and the nucleus.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
