Question

a tea strainerpermitting the passage of tea solution, but blocking the passage of tea leaves is

isotonic permeability

selective permeability

active transport

or phagocytosis

plesase explain answer

Answer 1

Answer-

According to the given question-

tea strainer is defined as a strainer which is placed on a pot or on tea cup to prevent the passage of tea leaves and allow passage of water.

Tea stainer are Selectively permeable because they allow passage of molecules ot ions and also inhibit the passage of other substance which are larger than their size. So Tea stainer filter as well as allow molecular transport so they are called selective permeable.

Isotonic permeability means movement of molecule s kept in same concentration of solution and separated by a membrane which is permeable for the solute.

Active transport require energy such as ATP for the transport of molecules across the membrane and with the help of carrier proteins.

Phagocytosis- is the ingestion process by some cells such as macrophages or by the organism ingest the substance inside it.

so the correct answer for the question a tea strainer permitting the passage of tea solution, but blocking the passage of tea leaves is (B) selective permeability
