The correct answer is a nutrient runoff.
Nutrient runoff is a major reason for eutrophication of surface waters, in which extra amount of nutrients, generally phosphorus or nitrogen, instigate growth of algae. Sources of nutrient pollution involve surface runoff from pastures and farm fields, emissions from combustion, and discharges from septic tanks.
Answer:
Saturated fats contain only single carbon bonds in the carbon chain
Explanation:
Differentiation in plants refers to the processes by which distinct cell types arise from precursor cells and become different from each other. Plants have about a dozen basic cell types that are required for everyday functioning and survival. Additional cell types are required for sexual reproduction. While the basic diversity of plant cell types is low compared to animals, these cells are strikingly different. For example, some cells such as parenchyma cells retain the potential to respond to environmental and/or hormonal signals throughout their life and, under the right conditions, can be transformed into another cell type (transdifferentiation). Other cells such as the water-conducting vessel elements undergo cell death as part of their differentiation pathway and thus can never transdifferentiate to another cell type

The study of a living being is called biology. There are two types of species that are living and these rare plants and animals.
The correct answer is described as follows
<h3>What is taxonomy?</h3>
- The classification of the species and arranging them into different hierarchy levels is called taxonomy.
The criteria for the classification is changed over periods of time and still changing as we are developing in modern science.
The first classification has used the habitat to classify the species. After that various scientists came they start to classify the species in a different manner.
The other classification is based on the cell wall and cell organization.
After that, the final classification is based on the 5 different criteria out of which the criteria are:-
- cell level
- cell organisation
- mode of nutrient
- mode of reproduction
- tissue level
Hence, the answer is mentioned as described.
