Hey mate, here is your answer
Three ways by which nitrates are transferred from the land to water are :-
Δ The roots of the legumes undergoes symbiotic association for the intake of nitrogen. They form nitrates. So these plants help in transferring solid nitrate to water nitrate
Δ Animal wastes has nitrates. So these nitrates along with rain water can go to rivers
Δ The lightening strikes contain nitrogen which is converted by plants during nitrogen cycle into nitrates which then eventually goes into water
EFFECT ON HUMAN HEALTH
The nitrates are good when eaten. They help in proper functioning of body parts. But its also harmful if its contain is too much. Nitrate and Methemoglobinemia. Methemoglobinemia, or blue-baby syndrome, is a condition caused by the inability of the blood to deliver enough oxygen to the body. It is the most well-known effect of exposure to elevated levels of nitrate in drinking water.
EFFECT ON ENVIRONMENT
Nitrate in water is too dangerous for animals in aquatic. They can die if they start consuming nitrates
Answer:
The action potential rate will be doubled
Explanation:
The logarithm of a number for a given base is the power to which the base must be raised to give the number. Logarithm of a number can be in different bases. The base of common logarithm is the base 10.
For example, logarithm of 1000 to base 10 is 3 because 10 raised to power 3 equals 1000
Log₁₀1000 = 3 since 10³ = 1000
Therefore, if there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons and the stimulus intensity increases by 100, the action potential rate will increase thus:
Log₁₀100 = 2
Therefore, the action potential rate will be doubled
Answer: cell wall
Explanation: a cell wall is a complex protective structure which gives shape and protection to a plant cell.
Among the functions of a cell wall is maintaining the structural integrity of a cell and providing strength. Because a cell wall has semi-permeable outer layer, it filters molecules that pass in and out of the cell hence, acting as a defense structure against a variety of external factors. It has pores and receptors that regulate various functions of the cell.
Radiant and kinetic is the answer.
Hope this is not too late..
Please ask a school question next time please.
