Briefly explain how an antibiotic-resistance gene and the lacz gene can be used to determine which cells contain a particular pl
viktelen [127]

Bacteria that have taken up the plasmid with antibiotic resistance gene will grow in a medium laced with the particular antibiotic of interest. More so, the bacteria that take up plasmid with the lac Z gene, when grown in a medium of lactose only, will propagate. These experiments are used with selective media that only allows the bacteria with a particular characteristic to grow.

How is osmosis different from diffusion
kupik [55]
Diffusion is a spontaneous process in which molecules move with their concentration gradient. For example, if you place food coloring in water, the food coloring will slowly diffuse through the water until the entire solution has been balanced.

Osmosis is specifically the movement of <em>water</em> through a semipermeable membrane - meaning a membrane that can let some substances in but keep others out - and, similar to diffusion, it moves with its concentration gradient. For example, if you place a glucose solution sealed in plastic in water, water will move into the plastic to even out the concentration of glucose in the entire solution because glucose is too large to diffuse freely.

Hope this helped!
