Carbohydrates are your body’s main source of energy. The amount of carbs a man should consume daily depends on his age and activity level. The Institute of Medicine suggests adults to eat at least 130 grams of carbs a day. But If you’re a competitive athlete like Shana, you need additional amount.
<span>A study made by The Academy of Nutrition and Dietetics recommends a 2.3 to 4.5 grams of carbohydrates per pound of body weight each day, to athletes depending on the intensity of training. Therefore, Shana who weighs 135 lbs, needs approximately 310.5 grams carbohydrates daily for her physical workouts. </span>
Answer:
Chlorophyll "a"
Explanation:
The reaction centers of the photosystem have chlorophyll "a" molecules. The chlorophyll "a" that functions as a reaction center for the photosystem II has absorption maxima at 680 nm and therefore, it is called P680. The reaction center of photosystem I also have chlorophyll "a" molecules that have the absorption peak at 700 nm. The chlorophyll "a" molecules serving as reaction centers transfer the photoexcited electrons to a primary acceptor during the light-dependent phase of photosynthesis.
Higher phosphates is typically associated with a large amount of organic material in a water supply. A large amount of organic material implies rapid growth, so higher phosphates is the only feasible choice.
