<span>Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0 and 100%.</span>
Answer:
The sun is located at one of the two foci in the shape of Earth's orbital path
Explanation:
The answer to fill up the blank is foci.
Using hydrogen in his experiments Bohr showed that an electron spins around the atom nuclei at a specific/discrete radii (orbital levels). Electrons at every orbital level spin at a discrete angular momentum and energy. When the electron moves one orbital level down, it releases a photon of energy specific to the jump (that is, of a particular spectrum that is unique to the atom). When the electron goes up an orbital level, energy (of a specific spectrum) is absorbed. This emission and absorption spectrum varies across atoms and is calculated as (delta)E = hf where;
E = energy
h = Planck's constant
f = frequency
Antibiotics are usually what can help. Depends what kind of infection you get and how severe it is.
When DNA ligase has compelted its job catalyzing the formation of a phosphodiester bond to bring together the backbone of two separate DNA strands and bind them together, the result is that two separate strands of DNA become one.
