Answer:Because plasma membrane structure contain Llipids and protein.
Explanation:
Lipid make it differential permiable while protein make it selectively permiable , Protein act as carrier (permiase) Also Act as receptor and provide receptor site , control the concentration of substance and many other function.
Answer:
A. More hydrogen ions inside the membrane than outside it
Explanation:
During electron transfer from water molecule to PS II and then through electron transport chain to the PS I pumps the hydrogen ions inside the thylakoid lumen. ATP synthesis is driven by energy of proton concentration gradient that moves the hydrogen ions (protons) from lumen of thylakoid membrane towards the stroma. Hence, ATP synthesis requires presence of more hydrogen ions inside the membrane.

Cell biologists photograph cells in mitosis, then cut out the chromosomes from the photographs and group them together in pairs to form a karyotype.
No because there are different types of cells and they have different processes.
