Outline three examples of cycles of inorganic nutrients. For each, outline the uses of the nutrients in living organisms, its me
Serggg [28]

The three examples of cycles of inorganic nutrients are Nitrogen, carbon and sulphur cycle.

Nitrogen is required to make amino acids and DNA in organisms. Carbon is the main component of glucose through which organism make energy, about 18 per-cent of the human body comprises carbon. Sulphur is an important constituent of some proteins, amino acids and enzyme cofactors.

Explanation:

The biogeochemical cycles like the nitrogen cycle are responsible for converting nitrogen into many chemical forms as nitrates, nitrites, ammonia. This process involves degrade decomposing animal and plant matter and naturally cleaning the environment also nitrites and nitrates become biofertilizers. The plants take nitrogen through their roots and in turn primary consumer in food chain ie. organisms consume the plant and eventually releases nitrogen as a waste material, dead and decaying body to the soil and cycle goes on.

In the carbon cycle the carbon is exchanged from the atmosphere to the organisms and then again to the environment. Plants perform photosynthesis by using carbon dioxide, primary consumer eats it and gets nutrition to perform cellular respiration, in turn, gets energy which gets dissipated and stored as biomass eventually in the course consumer die and replenish the soil with carbon. The Carbon emitted will keep cycling through air, water and soil.

The sulphur cycle involves the movement of sulphur between rocks, water and living beings and plants. Plants ( producers) absorb sulphur dissolved in water and animal consume these plants to replenish their sulphur requirement. And when organism die, sulphur enter the cycle again.

There will be a transfer of these inorganic nutrients to the trophic level in food chain.

Describe the relationship between the wavelength and frequency of electromagnetic waves
larisa [96]

Answer:

Frequency is inversely proportional to wavelength.

Explanation:

frequency is the number of oscillations in a unit of time.

Wavelength is the length between one oscillation and the next oscillation.

take two springs and 4 pins. (springs should have loops or hooks at terminals to attach to pins.)

Now get two pins and pin them at a certain distance apart.

take the first spring and attach its two terminals to the pins.

Repeat the above procedure, but double (increase the distance x2) the distance between two pins.

Now you have to measure how many coils are there within 5cm of the two springs.

you'll observe that the second spring has half the coils of the first spring within 5cm.

In here no. of coils is the frequency

5cm length is time.

distance between coil is the wavelength.

If the PP of a test Protocol was 32 then the BP would have to be..
Harlamova29_29 [7]

Answer:

The correct answer would be - 120/88 or 112/80

Explanation:

Pulse pressure or PP is the difference between the top or higher number (systolic) and the bottom number (diastolic) blood pressure. Pulse pressure can find out by the systolic minus the diastolic of Blood pressure.

For example, if an individual's resting BP is 120/80 millimeters of mercury (mm Hg), the normal PP is 40 which is considered a healthy pulse pressure. So, as per the normal BP 120/80, if the pp was 32 than the bp would be 120/88 or 112/80.
