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.
Answer:
Hydrogen bonds make water molecules spread out when they freeze. This makes ice less dense than water and allows ice to float. If ice did not float then oceans and lakes would freeze from the bottom up, killing marine life by trapping organisms in the ice. When ice floats, it insulates the water below, keeping it at around 4 degrees C or 40F, which does not freeze and allows fish to survive the winter.
Explanation:
They both eat zooplankton I think
The answer is B.
neutral: OH- = H+
acid: H+ > OH-
base OH- > H+
