Answer:
C. Electrons are released into the electron transport system.
Explanation:
Photosynthesis has both light dependent processes and light-independent processes. In the light-dependent reactions, photosystem II is the first protein complex. Photosystem II is present in the thylakoid membrane of plants.
<em>When the photons or light energy hits photosystem II, the free electron excites and released into the electron transport system (series of proteins). </em>The electron then passes through electron transport system and the energy from the electron fuels the hydrogen ions to move against their concentration gradient. Once the energy is utilized, the electron is accepted by photosystem I.
Hence, the correct option is C.
The first evidence of modern human traits, including increasing brain size and dependence on material culture shows up in Homo habilis. Even though they are species<span> of genus </span>Homo, they are not similar to people nowadays at all. <span>In </span>palaeoanthropology, these species were the first ones who left Africa and started to move and spread along Eurasia, which is one the main facts and characteristics of Homo habilis.
