How is mass defect determined?

Biology

<span>Mass defect is the difference between predicted and actual experimentally determined mass. The predicted mass of a sample is found by adding the mass of the neutrons and protons (to be accurate, electrons as well) within that sample, and we know what the individual masses of these particles are so multiplication isn't a problem. This mass is usually higher than what is measured experimentally because some of this mass turns to binding energy with the relationship e is roughly equal to m(c)^2.

If you are asking how we possibly add the masses of all those atoms of the Helium and Hydrogen we experiment with, we do it using the formula (number of atoms * number of protons per atom) + (number of atoms * number of neutrons per atom) + (number of atoms * number of electrons per atom). The number of atoms is found using the total mass of the sample alongside some experimental data.</span><span>

Pea plant clones are given different amounts of water for a three-week period. First pea plant receives 400ml. Second pea plant
borishaifa [10]

Answer: The independent variable is the different amount of water. The correct option is A.

Explanation:

A variable can represent age, a person, or an entity that can be measured. In statistics, it is simply defined as an attribute of an object to be investigated. There are different types of variables these includes:

--> Dependent variable and

--> Independent variable.

Dependent variables are simply the variables that are affected by the changes that occurs in the experiment. From the experiment they should include:

--> the height of the plant,

--> the size of the plant,

--> the number of leaves

---> if the plant survived or not (dead).

Independent variable are the variables that are changed in the experiment. A good example from the pea plant experiment is WATER. It is the aspect that is used to alter the dependent variable which is the height of the pea plant. I hope this helps, thanks!
