When someone is lactose intolerant, it means its intestine cannot absorb lactose, which will stay in the lumen and be consumed by intestinal bacteria and produced gases, that's why intolerant lactose people have flatulence and abdominal pain while eating food with lactose in it.
Let's go back to the question, before being consumed, lactose in the lumen intestine will attract water from the enterocytes to its side by oncotic pressure.
Do not confound oncotic pressure (which concerns macromolecules like sugar or proteins) and osmotic pressure (which concern micromolecules like small ions (sodium potassium and chloride...)).
Answer:
pfu/ml
Explanation:
Given -
Bacteriophage dilution ml
Volume of bacteria and plate with top agar ml
Number of plaques pfu
Dilution (d)
Final concentration of phage stock is equal to
Where pfu is the count of plaques
d is the dilution and v is the volume
Substituting the given values, we get -
pfu/ml
An animal cell will only have a cell membrane, a plant cell will have a cell membrane and a cell wall
