Sequence for the movement of electrons during the light dependent reaction
Explanation:
1.These reactions occur within specialised membrane discs within the chloroplast called thylakoids and involve three steps: Excitation of photosystems by light energy. Production of ATP via an electron transport chain. Reduction of NADP+ and the photolysis of water.
2.The cyclic light-dependent reactions occur only when the sole photosystem being used is photosystem I. Photosystem I excites electrons which then cycle from the transport protein, ferredoxin (Fd), to the cytochrome complex, b6f, to another transport protein, plastocyanin (Pc), and back to photosystem
3.Light-dependent reaction. In photosynthesis, the light-dependent reaction uses light energy from the sun to split water (photolysis). ... Water, when broken, makes oxygen, hydrogen, and electrons. These electrons move through structures in chloroplasts and by chemiosmosis, make ATP
4.The two products of the light-dependent reactions of photosystem are ATP and NADPH. The movement of high energy electrons releases the free energy that is needed to produce these molecules. The ATP and NADPH are used in the light-independent reactions to make sugar.
Answer: A. is a measure of energy
Explanation:
Heat is one of the easiest forms of energy that man can detect in your environment because we have the sensation of cold, hot, sweat, drink liquids when we feel hot, see the engine of a car heat up, take a bath of water heated by an electric shower or a boiler, etc.
Heat transfer occurs until the moment bodies reach the same temperature (thermal equilibrium). Heat is the energy transferred between a system and its surroundings because of the differences in temperatures.
Sound waves<span> coming from farther above, where it is warmer, will experience a refraction. The change in speed from the warmer </span>air<span> to the cooler </span>air<span> causes a bending effect, as the </span>sound travels<span> downward.</span>
In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.
Answer: Option C.
Tundra
Explanation:
Tundra is a biome that has low Precipitation. Precipitation is a form of water that fall from the atmosphere to the Earth surface. Which could be inform of snow, sleet e.t.c.
Tundra is the coldest of all types of biomes. It has low temperature, little precipitation,low nutrients. It is located near the north Pole of the Earth. It is characterized by permafrost, permanent frozen layer on its surface.
