Tell two things that happen to put h+ ions in the thylakoid space during the light dependent reactions

Electron transfer and presence of thylakoid membrane proteins

Explanation:

The high energy electrons from chlorophyll pass through a chain of proteins called electron transport chain in the thylakoid membrane. These high energy electrons helps H+ ions to come from outside to inside membrane of thylakoid against the concentration gradient which is also contributing factor to build the concentration of H+ inside thylakoid membrane which is used to transfer phosphate to ADP during light depend reactions.

thymine. in rna, thymine is replace by uracil

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.
