Answer:
a. the pH within the thylakoid is less than that of the stroma
Explanation:
The pH of thylakoid membrane is 8 at normal conditions but it became highly acidic like 4 during photosynthesis. The electron transport chain utilize the energy released by excited electrons to pump the H+ ions to lumen of thylakoid membrane from stroma during light reaction of photosynthesis. The H+ ions are present in both the stroma and thylakoid membranes. These high potential H+ ions are utilized by ATP synthase complex for the production of ATP.
We know that more the H+ ions lesser will be the pH and lumen have the high concentration of H+ ions. While the pH of stroma is normally kept acidic by plants to create a concentration and potential difference of H+ ions for the production of ATP. That why the lumen have lower pH than stroma of chloroplast.
Answer:
The individual is a male. Explanation: In mammals, sex is determined by a pair of sexual chromosomes.
It is called data which is a collection of results
Answer;
-Matrix
Explanation;
Matrix is used to maintain artificial wall around the tooth preparation.
Cavity preparation is the mechanical alteration of a tooth to receive a restorative material which will return the tooth and area to proper form, function and esthetics.
-Objectives of cavity Preparation: remove all defects and give the necessary protection to the pulp, locate the margins of the restoration as conservatively, form the cavity so that under the forces of mastication the tooth or the restoration will not be displaced and also Allow for the esthetic and functional placement of a restorative material.
