Explanation:
Nitrogen is an essential element for plant growth and development; however, due to environmental pollution, high nitrate concentrations accumulate in the edible parts of these leafy vegetables, particularly if excessive nitrogen fertilizer has been applied. Consuming these crops can harm human health; thus, developing a suitable strategy for the agricultural application of nitrogen fertilizer is important. Organic, inorganic, and liquid fertilizers were utilized in this study to investigate their effect on nitrate concentrations and lettuce growth. The results of this pot experiment show that the total nitrogen concentration in soil and the nitrate concentration in lettuce increased as the amount of nitrogen fertilizer increased. If the recommended amount of inorganic fertilizer (200 kg·N·ha−1) is used as a standard of comparison, lettuce augmented with organic fertilizers (200 kg·N·ha−1) have significantly longer and wider leaves, higher shoot, and lower concentrations of nitrate.
Nitrogen is a critical element for plant growth and development; however, due to environmental pollution, high nitrate concentrations get in the edible regions of these leafy vegetables, particularly if excessive nitrogen fertilizer has been involved.
What are nitrate-containing fertilizer?The main nitrate fertilizers exist as ammonium, sodium, potassium, and calcium salts. Nitrate exists highly reachable and can efficiently travel with water from the soil if there stands excessive rainfall and can get groundwater.
Nitrates in the soil exist as a primary source of nitrogen which is important for plant growth. Under normal conditions, nitrates are transformed to protein in the plant at about identical rates as they exist absorbed into the root system.

a) What is the role of neutrons in an atom?
b) How do we determine how many neutrons are in an atom?
Answer:
numer 1:Neutrons are required for the stability of nuclei, with the exception of the single-proton hydrogen nucleus. Neutrons are produced copiously in nuclear fission and fusion. They are a primary contributor to the nucleosynthesis of chemical elements within stars through fission, fusion, and neutron capture processes.
number 2:The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).let me know if i helped
what is the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom?
Answer:
9.13 x 10^-8 m
Explanation:
The maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.
What is wavelength?
Wavelength is defined as the distance between identical points in the adjacent cycle of a waveform signal propagated in space or along the wires.
Wavelength is calculated as wave speed and frequency.
Wavelength = speed/frequency
SI unit of wavelength is meter.
A ground state atom is an atom in which total energy of the electron can not be lowered by transferring one or more electrons to different orbitals.
Thus, the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.

Write Cadmium nitride formula using criss cross method
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here calcium is having an oxidation state of +2 called as Ca^{2+}Ca2+ cation and NO_3^{-}NO3− is a polyatomic anion with oxidation state of -1.. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral Ca(NO_3)_2Ca(NO3)2

32: 6.45062
33: 12.50400
34: 210.42700
35: 63.88200 cm
36: -970.8772
Explanation:
4.550 x 300.4 = 1366.82
2.45002 + 4.0006 = 6.45062
26.004 - 13.5 = 12.50400
2.667 + (5.6 x 37.1) = 210.42700
2.34 x 4.55 x 6.0 = 63.88200
4.60 x 5.16 x 1.05 + 6.2 - 1002 = -970.8772

how are the light reactions and the calvin cycle connected?
Answer:
The light reactions provide the Calvin cycle with oxygen for carbon fixation, and the Calvin cycle provides the light reactions with sugars to produce ATP. The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the Calvin cycle provides water and electrons to the light reactions.
Explanation:
The energy that drives the Calvin cycle comes from ATP and NADPH produced by the light reactions, that is, the energy capture reactions in the first stage of photosynthesis.
The Calvin cycle is a process that results from photosynthesis made by plants, through which Carbon dioxide is absorbed and transformed into organic material or biomass.
In the light phase, light energy is stored in organic molecules that provide energy to carry out the process (ATP) and have the ability to donate electrons (reducing power) to another molecule such as NADPH.These molecules formed in the light reactions participate in the reactions that make up this cycle during which carbon dioxide (CO2) taken from the atmosphere is fixed, incorporating it into the body in the form of glucose thanks to the action of the enzyme RuBisCo.Therefore, we can conclude that the molecules constituted in the light reactions (ATP and NADPH) participate in the reduction of carbon dioxide (CO2) through the series of reactions of the Calvin Cycle.
