Starch cannot diffuse across the membrane because starch molecules are too large to fit through the pores in the dialysis tubing, whereas iodine is a smaller molecule and therefore can diffuse across.
Answer:
Antibiotic resistance occurs when bacteria do some variation in their genome that allows bacteria to eliminate the effect of antibacterial drugs. Irregular or excessive antibiotics use is the main cause of generating antibiotic resistance bacteria.
So antibiotics should be taken only on the prescription of doctors and a complete course of antibiotics should be done to eliminate all the bacteria so that no bacteria is left to generate antibiotic-resistant bacteria.
Antibiotics should be avoided in viral infection as antibiotic does not kill viruses as it is only beneficial in bacterial infection.
If a solid object is cut in half, the mass and volume are both divided by two, but the density remains the same.
<h3>What is an intensive property?</h3>
Intensive property is a property that does not depend on the quantity of a substance while an extensive property depends on the quantity.
Mass and volume is an example of extensive physical property while density is an example of intensive property.
This suggests that if a solid object is cut in half, the mass and volume are both divided by two, but the density remains the same.
