Answer:
Dopamine, like caffeine, increases the heart rate of Daphnia in a dose-dependent manner. Dopamine's effects on Daphnia's heart has not been reported previously. ... Caffeine showed a similar effect on Daphnia's heart rate at a 10-times lower concentration than dopamine (28.5% increase at 0.08 mg/ml, Figure 2).
Explanation:
Answer:
They use it in photosynthesis
Explanation:
When animals practice cellular respiration, the biproducts, such as CO2, are released into the environment. When a plant practices CR, the biproducts are immediately used as key reactants in photosynthesis.
Answer:
D) The hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. In the Calvin cycle, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
Explanation:
Photosynthesis is the process by which plants produce carbohydrates (sugars) from carbon dioxide in the atmosphere and water using the energy of sunlight. The process of photosynthesis occurs in two stages: (i) the light-dependent stage and (ii) the light-independent stage.
Light reactions: In this stage, the hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. Also, the energy storage molecule ATP and the reduced electron carrier NADPH are produced.
Light-independent reaction or Calvin cycle: in this stage, carbon atoms from CO₂ are incorporated into ribulose-5-phosphate and used to produce glyceraldehyde-3-phosphate, a three-carbon sugar using the energy of ATP and NADPH from the light reactions. Essentially, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
Colder climates give the people longer noses so the air has a good time to warm up before going into the lungs. places with more light or sun had more pigmented skin to protect from the rays and getting burned
Pretty sure it’s the human genome project
