Answer: true 
Explanation: In gel electrophoresis, the smaller the size/molecular weight of DNA the faster it moves across the gel and vise versa. This is as a result of the pore size of the gel which is usually prepared 1g of agarose in 100ml of distilled water. So a DNA fragment with 1000 base pairs will "struggle" its movement across the gel pore making it mive less faster and further. Movement and molecular weight of DNA are inversely proportional.
 
        
             
        
        
        
<span>the glucose-sodium cotransporter in animals, Na+ moves back into the cell down its electrochemical gradient, providing the energy for glucose to move into the cell against its concentration gradient.  
</span>It makes sense css <span> glucose is cotransported with Na+ ions</span>
<span>In cotransport, the energy required to move one solute against its concentration or electrochemical gradient is provided by an ion moving into the cell down its electrochemical gradient. </span>

Answer:Rhythm 
Explanation:
This is because rhythms are repetitive, cyclical patterns of behavior generally. For example waking, eating are examples of rhythm for a baby.
