Answer:This protein uses the energy released from hydrolysis of ATP (adenosine triphosphate) to pump three sodium ions out of and two potassium ions into the cell. ... Transport that directly uses ATP for energy is considered primary active transpor
Explanation:
Answer:
Light reactions and Calvin Cycle
Explanation:
The products of the light reaction become the products of the Calvin cycle (which is the dark stage) of photosynthesis. The light reaction is called so because it harnesses the energy of the sunlight photons to split water molecules into H+ and O- . The CO2 is then reduced to glucose using the H+ in the Calvin cycle without the need for sunlight - hence referred to as the dark reaction. The light reaction occurs in the grana while the dark reaction occurs in the stroma.
<span>The correct answer to the question, 'which of the following scenarios is representative of how agricultural practice can affect the environment' is A. Option A is chosen because it is the only option that refer to another environment which is different from that of the farm. When fertilizers are washed to nearby ponds as a result of erosion, it causes a lot of negative changes in the pond. For instance, the chemicals in the fertilizer can be poisonous to some of the smaller organisms in the pond, this will result in the death of these organisms. Fertilizer run off can also cause excessive growth of plants such as algae in the pond. This may block out the light necessary for the survival of the organisms in the ponds and may also reduce the amount of oxygen available to the organisms living in the pond.</span>
C. Oxygen and nutrients taken in by the respiratory system are transported to the circulatory system for transport around the entire body.
Also, B and D cannot be correct, as carbon dioxide is not wanted in the body (it's a waste product of respiration of the body cells)
