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.
DNA replication goes in the 5' to 3' direction because DNA polymerase acts on the 3'-OH of the existing strand for adding free nucleotides. DNA replication can take place both the directions chemically. ... But these nucleotide triphosphates hydrolyze spontaneously under aqeuous conditions.
Continuous conduction takes place in unmyelinated axon.
Explanation:
Based on the presence and absence of myelin sheath, the neurons had been classified as myelinated and non-myelinated neurons respectively.
In myelinated neurons the transmission of impulse takes place only at the non myelinated region called nodes of Ranvier. Due to this, the conduction in Myelinated neuron is saltatory.
The conduction in non-myelinated neuron takes place throughout the length of axon and it is continuous.
Saltatory conduction is faster than continuous conduction.
Amylase is an enzyme that helps to break down starch into simpler sugars. Amylase functions within the mouth or the small intestine. However, amylase is produced in either the salivary glands, pancreas, or small intestine. Amylase is one of the many different kinds of enzymes that are found within the body.
