Answer and Explanation:
Hydrogen ions in the thylakoid space form an electrochemical gradient because of the difference in the concentration of protons (H+) and the difference in the charge across the membrane that they create. This potential energy is stored as chemical energy in ATP through chemiosmosis. The hydrogen ions are allowed to pass through the thylakoid membrane through an embedded protein complex called ATP synthase. Energy from the electron fuels membrane pumps that actively move hydrogen ions against their concentration gradient from the stroma into the thylakoid space. The photon causes an electron in the chlorophyll to become excited.

The falciform ligament separates the<u> a. right and left lobes of the liver.</u>
Explanation:
- The falciform ligament is a ligament that attaches the liver to the front body wall, and separates the liver into the left medial lobe and left lateral lobe.
- The falciform ligament is a broad and thin peritoneal ligament. It is sickle shaped and a remnant of the ventral mesentery of the fetus.
- The falciform ligament droops down from the hilum of the liver.
- It contains between its layers a small but variable amount of fat and its free edge contains the obliterated umbilical vein and if present, the falciform artery and paraumbilical veins.
- The falciform ligament divides the left and right subphrenic compartments but may still allow passage of fluid from one to the other.
- The falciform ligament stretches obliquely from the front to the back of the abdomen, with one surface in contact with the peritoneum behind the right rectus abdominis muscle and the diaphragm, and the other in contact with the left lobe of the liver.
Answer:
Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve
