During a spring tide, what is arrangement of the moon, the sun and the earth?.
Solnce55 [7]

Explanation:

Spring tides generally occur twice a month—during new and full moons, when the Earth, Sun, and Moon line up in a row. In this arrangement, the gravities of the Sun and Moon work together and have the strongest pull on Earth. This produces the largest difference between high and low tide.

Spring Tides

During full moon or new moon phases, the gravitational forces of the Sun and Moon are maximized, producing very large ranges of tidal highs and lows called spring tides

Gel electrophoresis is a technique used to separate nucleic acids by their _______.
ss7ja [257]
<h2>Answer: size</h2>

Gel electrophoresis is called to the  technique used by scientists for analytical purposes, in life sciences laboratories to separate macromolecules (DNA, RNA, and proteins from various sources).

The process consists of separating the molecules according to their <u>size</u> and <u>electric charge</u>. This is done with a gel (a gelatinous substance extracted from seaweed, called <em>agarose</em>) of controllable porosity placed in an ionic buffer environment. This is how the gel acts as a molecular sieve that separates larger molecules from the smaller ones, because each molecule has different size and charge and will move through the gel at different speeds.

That is, the smaller molecules move more quickly through the gel while the larger ones are left behind.
