Experimenting. Experimenting is used in all three main branches of science, physics, chemistry, and biology, and is used in all the sub-branches of science, like marine biology, to make discoveries. Without experimenting, all we know about science would be random guesses.
Carl Woese distinguished between the members of the archaea and the bacteria using studies of their ribosomal RNA.
What is ribosomal RNA?
Ribosomal RNA (rRNA), a particle in cells that are sent out to the cytoplasm and is a part of the protein-creating organelle known as a ribosome, supports the change of courier RNA (mRNA) into protein. Moreover, ribosomal ribonucleic corrosive is a type of non-coding RNA that fills in as the primary structure block of ribosomes, which are essential for all cells. Protein combination is done by rRNA, a ribozyme, in ribosomes. In spite of never being converted into proteins, it makes up around 80% of cell RNA.

Answer:
Addition used for 'either or' events , Multiplication used for 'and' events
Explanation:
Addition is used when Probability is of 'one event <u>or</u> other event'
Multiplication is used when Probability is of 'one event & other event'
Ex : Probability of A winning = 0.4
Probability of B winning = 0.3
Probability (A or B winning) = 0.4 + 0.3 = 0.7
Probability (A & B winning) = 0.4 x 0.3 = 0.12
Answer:
<em>6</em><em> </em><em>minutes</em>
EXPLANATION:
The brain can survive for up to about six minutes after the heart stops. The reason to learn cardiopulmonary resuscitation (CPR) is that if CPR is started within six minutes of cardiac arrest, the brain may survive the lack of oxygen. After about six minutes without CPR, however, the brain begins to die.
