A fathom is a unit of length, usually reserved for measuring the depth of water. A fathom is exactly 6.00 ft in length. Take the

iragen [17]

Answer:

216480000 fathoms

Explanation:

1 fathom = 6 feet

$1\ feet=\frac{1}{6}\ fathom$

Distance from Earth to the Moon = 246000 miles

Converting to feet

1 mile = 5280 feet

246000 miles = 1298880000 feet

Convert to fathom

$1\ feet=\frac{1}{6}\ fathom\\\Rightarrow 1298880000\ feet=\frac{1298880000}{6}=216480000\ fathom$

So, the distance between Earth and Moon is 216480000 fathoms

How do plant and animal cells function differently

e-lub [12.9K]

Although, the overall function of the cell is the same, there are some important differences between animal and plant cells. The first difference is that plant cells have an organelle called chloroplast. Chloroplasts contain a pigment called chlorophyll (which gives the plant its green color).

Centrosomes and lysosomes are found in animal cells, but do not exist within plant cells.The lysosomes are the animal cell's "garbage disposal", while in plant cells the same function takes place in vacuoles.Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.

Hydrogen/hydronium ion concentration

Valentin [98]

Answer:

Pure water is considered to neutral and the hydronium ion concentration is 1.0 x 10-7 mol/L which is equal to the hydroxide ion concentration. So the pH is the -log of the [hydronium ion].
