The amount of nitrogen in the bay increases with a consequent increase in the population of algae(algae blooms).
In water bodies, there are small plants that are called phytoplankton and algae. These organisms depend on dissolved nutrients to survive in water. These dissolve nutrients some times enter into water bodies through surface run off.
When runoff from farms, suburban lawns, and wastewater treatment plants a watershed gets into a local bay, the amount of nitrogen in the bay increases with a consequent increase in the population of algae(algae blooms).

I'm not really sure, but I think the answer is A. Photosystems are the protein structures in plant chloroplasts that absorb light energy.
The right option is a. contour interval
The difference in elevation between the highest and lowest contour lines on a topographical map is called contour interval.
A contour interval is the vertical distance between the two contour lines (highest and lowest) in a topographical map. The contour interval is usually stated explicitly on the right-hand lower part in every map. 20 feet for a 1:24,000 map scale is the frequently used contour interval and different contour intervals is available for different maps.
Answer:
Central pattern generators
Explanation:
A central pattern generator (CPG) is a neuronal circuit consisting of neurons localized in the spinal cord capable of producing rhythmic outputs. CPGs are able to produce rhythmic movements even when the spinal cord is separated from the brain and sensory organs. CPGs are the main components of motor functions including, among others, breathing, flying, chewing, walking, swimming, etc. These neural circuits have been discovered in almost all vertebrates studied to date.
