reduction in biodiversity by eliminating spawning and nursery grounds of aquatic life
Explanation:
Estuaries are transition zones localized between rivers and marine ecotones. These regions are influenced by marine factors such as waves, tides, and saline water, while rivers provide freshwater and sedimentary material. The mixture between seawater and freshwater is generally highly nutritive, thereby estuaries often represent high-production systems where fishes and shellfishes spawn and grow. However, many estuaries have suffered the negative effects of human activities, including deforestation, drainage, overfishing, nutrient pollution, etc.
white is recessive since 2 fs were needed to get white so if half the children are white then the second parent has to have the recessive gene f and since the other half kids are purple then they need the G gene which is purple and is the dominant gene
