Answer:

A scientific experiment refers to a detailed and organized array of steps that are needed to reject or validate the framed hypothesis. The steps, which are incorporated in a scientific experiment are:  

1. Identification of independent variable: The independent variable is the one that can be manipulated or changed in an experiment, that is, the effect of which can be witnessed on a dependent variable.  

2. Address any confounding variable: It is the one that comes from the outside, the changes resulting due to this variable impart an effect over the independent and dependent variables. This variable can bring change in the outcome of the experiment.  

3. Form a non-falsifiable hypothesis: A non-falsifiable hypothesis refers to the one that can be proved true on the basis of the implementation of suitable methodology and research design.

The process of photosynthesis can be represented by the chemical formula
lakkis [162]

Answer:

Photosynthesis is defined as the process by which plants make their own food in the presence of sunlight by utilizing water and carbon dioxide and produces energy.

The whole of process of photosynthesis can be represented by the following chemical formula:

6CO2 + 6H2O + sunlight energy = C6H12O6 + 6O2

CO2 - carbon dioxide

H2O - Water

C6H12O6 - Glucose

O2 - Oxygen

During photosynthesis glucose is formed from water and carbon dioxide and produces energy which is further converted into pyruvate that releases adenosine triphosphate (ATP) through cellular respiration. Oxygen is also formed.

The process takes place in two sequential stages  Light dependent reactions and  light-independent reactions.

If the diameter of an atom is 1 × 10-8 cm, what is the approximate diameter of its nucleus
kotegsom [21]
Here we have to find the diameter of nucleus as the diameter of atom is given.
Diameter of atom is 1 x 10⁻⁸ cm
Radius of atom = diameter/2
so, radius of atom = 1 x 10⁻⁸ cm/2 = 5 x 10⁻⁹ cm
To find diameter of nucleus, first we have to find the radius of nucleus by using this formula,
R = rA⁽¹/³⁾     where <span>R = radius of nucleus, r = radius of atom and A is a nucleon number, which is different for every atom
so, R=(5x10</span>⁻⁹)A⁽¹/³⁾  
here atom is not mentioned, so we don't know the value of A
and Dimeter (D) = 2R, R = D/2
 D/2 = (5x10⁻⁹)A⁽¹/³⁾
Diameter of nucleus (D) = 2((5x10⁻⁹)A⁽¹/³⁾)
