Scientists can reduce uncertainty by performing repeated hypothesis testing trough experiments or observations that exhibit the same predictive outcomes.
<h3>What is hypothesis testing?</h3>
The expression 'hypothesis testing' makes reference to experimental and also observational methods used to test (either confirm or reject) a scientific hypothesis.
Hypothesis testing helps to reduce the level of uncertainty because the same results in different outcomes represent an excellent a measure of reliability by means of the scientific method.
In conclusion, scientists can reduce uncertainty by performing repeated hypothesis testing trough experiments or observations that exhibit the same predictive outcomes.

Answer:
nitrogenous bases (adenine, guanine, thymine, uracil, cytosine) which are part of the nucleotides
Explanation:
The genetic code is the set of rules within genetic material that carries information about products that have to be synthesized (usually proteins).
During the process of translation (protein synthesis) code in mRNA (formed during the transcription of DNA) is read thanks to ribosome and tRNA. Transfer RNA (tRNA) molecules carry amino acids (for protein formation) and read the mRNA three nucleotides at a time and that happens within the ribosome. Those nucleotide triplets on mRNA are called codons and they specify which amino acid will be added next during protein synthesis.
The genetic code is expressed in a simple table with 64 entries.
The action that will directly affect the gravitational force between two objects is increasing the pressure on the objects (option B).
<h3>What is gravitational force?</h3>
Gravitational force is a very long-range, but relatively weak fundamental force of attraction that acts between all particles that have mass; believed to be mediated by gravitons.
Gravitational force can also be referred to as the force due to gravity of a planet.
The gravitational force between two objects can be affected by the following factors:
- Increase in pressure
- Increase in temperature
- Increase in speed of objects
Therefore, the action that will directly affect the gravitational force between two objects is increasing the pressure on the objects.
