Answer:
I think is the second one
Answer:
Theory
Explanation:
A proved hypothesis usually becomes known as a theory.
Let's take an example. Remember the experiment for the Newton's law of universal gravitation. In an experiment like this, we should have a reference point, a hypothesis. The thought process would be, for example, to intuitively propose that the force of gravity depends on the masses of the two objects and the distance between them.
As a second step, sufficiently high number of experiments should be performed to prove this relationship with different masses and different distances to see how force correlates with the given variables.
Having noticed that the two masses are directly proportional to force and that force is inversely proportional to the square of a distance between the two objects, a proportionality constant is also found, so then we have an equation which would help us solve for the force of gravity between any two objects knowing their masses and the distance between them.
Overtime, after this hypothesis is proved analyzing substantial data, it becomes an accepted theory that can be used and applied.
In the blosum-62 substitution matrix, a large positive score corresponds to substitution that occurs frequently.
BLOSUM-62 is used to account for the type of substitution when comparing sequences. To identify the problem the first approach is examining the substitutions that have actually taken place in evolutionary related proteins.
From an examination of appropriately aligned sequences, substitution matrices have been deduced. A substitution matrix describes a scoring system for the replacement of any amino acid with each of the other 19 amino acids.
In these matrices, a large positive score corresponds to a substitution that only occurs relatively frequently, whereas a large negative score corresponds to a substitution that only occurs rarely. A commonly used matrix, the BLOSUM-62 stands for Blocks of amino acid substitution matrix.
Each column in the matrix represents one of the 20 amino acids, whereas the position of the single letter codes within each column specify the score for the corresponding substitution.

Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The chapter on atoms, molecules, and ions introduced the basic idea of nuclear structure, that the nucleus of an atom is composed of protons and, with the exception of
