Answer:
Agricultural activities that cause NPS pollution include poorly located or managed animal feeding operations; overgrazing; plowing too often or at the wrong time; and improper, excessive, or poorly timed application of pesticides, irrigation water, and fertilizer. Industrial farming practices, such as monocropping and intensive tillage, have also compromised soil health over time. ... Excessive fertilizer use can also cause a buildup of salts in soil, heavy metal contamination and accumulation of nitrate (which is a source of water pollution and also harmful to humans
Explanation:
However agriculture is both cause and victim of water pollution. It is a cause through its discharge of pollutants and sediment to surface and/or groundwater, through net loss of soil by poor agricultural practices, and through salinization and waterlogging of irrigated land.
Answer:
We can mold metals into different shapes because they are _malleable__.
Explanation:
Malleable (ability to be hammered into thin sheets)
Answer:
Photorespiration
Explanation:
RuBisCo is the enzyme that catalyzes the first reaction of the Calvin cycle which in turn is a rate-limiting step. Photorespiration is the process during which the enzyme RuBP carboxylase/oxygenase (RuBisCo) catalyzes the reaction between oxygen and ribulose 1,5-bisphosphate to form 3-phosphoglycerate and 2-phosphoglycolate.
These two products are useless for the metabolism of cells. Photorespiration occurs since the RuBisCo enzyme has an affinity for both CO2 and oxygen. When CO2 is not available, as it occurs when plants close stomata during hot dry days to prevent water loss, photorespiration takes place. Therefore, stomatal closing in C3 plants to prevent water loss promotes photorespiration.
The function of acetylcholinesterase in the synaptic left is to bind Ach receptors on the post-synaptic membrane and relays signal from the nerve. Acetylcholinesterase is an enzyme that catalyzes the breakdown of acetylcholine. Some other cholines functions as neurotransmitters. ACHE gene is found in the chemical synapses and neuromuscular junctions of cholinergic. Acetylcholinesterase belongs to carboxylesterase group of enzymes. During the time of neurotransmission Ach which is released from presynaptic neuron to synaptic cleft. Acetylcholinesterase is also found in red blood cells membranes whereby different forms constitute the Y blood group antigens.
