How does photosynthesis and cellular respiration depend on each other

Monica [59]

Photosynthesis is the process where plants create energy. It requires water, carbon dioxide and sunlight. The end result is glucose, which the plants consume, and oxygen. Cellular respiration requires oxygen and glucose. The end result is carbon dioxide, ATP, and water.

Calculate the wavelength, in nanometers, of the spectral line produced when an electron in a hydrogen atom undergoes the transit

Lapatulllka [165]

Answer: The wavelength of spectral line is 656 nm

Explanation:

To calculate the wavelength of light, we use Rydberg's Equation:

$\frac{1}{\lambda}=R_H\left(\frac{1}{n_f^2}-\frac{1}{n_i^2} \right )$

Where,

$\lambda$ = Wavelength of radiation

$R_H$ = Rydberg's Constant = $1.097\times 10^7m^{-1}$

$n_f$ = Final energy level = 2

$n_i$ = Initial energy level = 3

Putting the values in above equation, we get:

$\frac{1}{\lambda }=1.097\times 10^7m^{-1}\left(\frac{1}{2^2}-\frac{1}{3^2} \right )\\\\\lambda =\frac{1}{1.524\times 10^6m^{-1}}=6.56\times 10^{-7}m$

Converting this into nanometers, we use the conversion factor:

$1m=10^9nm$

So, $6.56\times 10^{-7}m\times (\frac{10^9nm}{1m})=656nm$

Hence, the wavelength of spectral line is 656 nm

How does the arrangement of particles determine the physical properties of different states of matter?

Usimov [2.4K]

Answer:

See explanation

Explanation:

Matter may exist in three phases; solid, liquid and gas. The state in which matter exists depends on the extent of intermolecular forces operating in the substance.

In solid particles, the molecules that compose the solid are close together because the molecules of a solid do not move from place to place but they continue to vibrate about their fixed position.

For liquids, the molecules that compose a liquid are in random motion but are less energetic than molecules of a gas.

In gases, the molecules are not held together at all. The molecules of a gas have the highest degree of freedom. They move from one point another at a high velocity.

Hence, the order of increasing degree of movement of the particles in different states of matter = solids<liquids< gases.

Solids have well arranged particles, the molecules of a liquid are a little more disorderly than liquid particles while gas particles are the most disorderly of all the states of matter.

Which organ serves as the primary site of amino acid metabolism (i.e. oxidation, transamination, deamination, gluconeogenesis, e

GarryVolchara [31]

Answer:

The liver

Explanation:

The liver -

In human beings the location of liver is just in the upper right portion of the abdomen , exactly below the diaphragm .

Liver is present in specifically vertebrates , and is responsible for various metabolism , like producing hormones , decomposition of the red blood cells , regulating the storage of glycogen and the synthesis of proteins .

Liver is the main site for the process of gluconeogenesis , amino acid catabolism .

Liver is the very organ , that has full urea cycle .

Hence , from the given information of the question ,

The correct term is the liver .
