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.
Answer:
The Core, Radiation Zone, Convection Zone, Photosphere, Chromosphere, and the Corona.
Explanation:
Answer:
If the force of gravity increases or gravitational force increases the weight of the Object D. Increases.
Fg = W = m•g
Fg = force of gravity
W = weight
m = mass of object
g = acceleration due to gravity.
g
When saturated air is cooled, it simply reaches its dew point. Dew point is simply the temperature at which dew begins to form.
Dew point of saturated air is already pre-determined by how much water vapor the air contains. A state of saturation exists when the air is holding the maximum amount of water vapor possible at the existing temperature and pressure. The higher the dew point, the higher the moisture content of the air. Cooling does not change the dew point of saturated air, rather its the level of saturation.
So if the air has more moisture, dew will form at a higher temperature and vice versa, but dew point is NEVER EVER GREATER than the air temperature.
Yes
Explanation:
Blowing a room-temperature air over an ice block will heat it because of convection.
Convection is one of the heat transfer modes that occurs in fluids.
- In convection, a hot and lighter fluid replaces a denser and cold fluid.
- It involves the actual motion of the particles of the medium.
- In this analogy, the blowing room-temperature is hot and lighter.
- It will replace the air close to the ice block body that is cold and denser
- As the hot air comes near the ice block, it loses some of its heat and warms the cold ice.
- In turn, the air becomes colder and moves away.
- This is simple convection in action.
