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.

Ok i will answer in previous question.
Answer:d. Digitizer
Explanation:
A digitizer is a device that is used along with the stylus. A digitizer is used to convert the hand drawn images into a format which can be used by the computer.
The images are drawn on the flat surface along with the stylus that appears on the screen of the computer monitor. This device is used as glass cover over the screen of the monitor.

Answer:
A per mineralized piece of wood is known as the "petrified wood."
Explanation:
The petrified wood are available in few parts of the world with variety of colors, which happens as a result of presence trace elements inside the mineral by which the petrified wood is made.It is also believed that they are the remaining of the fossils of terrestrial vegetation. It is made from tree or some tree like plants which have been undergone mineralization process. These woods are much heavier than the normal one.
