Answer is (c). Excess nitrogen dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode.
The fertilisers contain urea which is a Nitrogen based compound. The use of fertilisers in farms leads to the water run offs carrying the excess amount of it to the nearby water bodies. The algae in the water bodies require Nitrogen to synthesise the proteins needed for their growth. The increase in the dissolved Nitrogen in the water bodies due to the run off boosts the growth of algae by fulfilling their requirements.

Answer;
-Sugar
Starch and glycogen molecules are a means for a plant or animal cell to store sugar in order to help maintain homeostasis.
Explanation;
-Sugars are the major sources of energy for organisms, both plants and animals through the process of cellular respiration.
-In plants simple sugars which are the products of photosynthesis are stored in the form of starch, which act as food reserve and is used when necessary.
-In animals glucose is stored in the liver in the form of glycogen. When the sugar levels are high, glucose is converted to glycogen for storage, and when glucose levels are low or when the body has exhausted the available glucose, glycogen is broken down to glucose.
Its B: which is sugar
The answer is Gravity. To ensure the one-way flow of blood the veins contain a network of valves which arteries do not have. The reason is for the veins to counteract the force of gravity on flow of blood. For example, to increase the pressure of the blood back to the heart the veins must counteract the force of the gravity.
Answer: A) gravity
