Answer:
The correct option is : B. Acids and bases will neutralize each other.
Explanation:
Acid is a proton donor and electron-pair acceptor. Whereas, a base is a hydroxide ion donor and electron-pair donor.
The addition of an acid or a base can affect the pH of a solution. Acids lower the pH of a solution, whereas bases increase the pH of a solution.
The pH of an acidic solution < 7 and pH of a basic solution > 7.
When equal amounts of acid and base is mixed together, the solution gets neutralized. This is known as Neutralization reaction. The pH of such a solution is neutral (pH= 7).
<span>Phylogenetic tree is a tree that shows the evolutionary relationships between several species or other entities that are believed to have a common ancestry. A phylogenetic tree is a form of a cladogram.
In addition, a phylogenetic tree serves to determine the minimum number of divisions necessary to obtain a specific cell or tissue. From here, you can study, for example, the mutations generated throughout the process.</span>
The answer is B (speed up chemical reactions).
B. The bases in DNA in the nucleus. The way our nitrogenous bases are arranged in DNA (A, T, C, and G) code for traits.
Role of Rosalind Franklin
Rosalind Franklin used X-ray diffractometry techniques to determine carbon structures, including graphite. Then she devotes herself to the structure of DNA. Thanks to X-ray diffractometry, which she applies to DNA, Rosalind Franklin manages to determine its structure by distinguishing, thanks to its photos, the two propellers, named A and B.
Rosalind Franklin was a victim of the Matilda Effect:
The Matilda Effect is the phenomenon that women scientists do not benefit much from the fallout of their discoveries when they do not see the Nobel simply escape them. Among them, Rosalind Franklin, the discoverer of DNA.
The photo taken by Rosalind Franklin, at the origin of his deductions, became essential for the research conducted by James Dewey Watson and Francis Crick on the helical structure of DNA.
James Watson and Francis Crick publish their model in Nature in April 1953, thanking Wilkins and Franklin.
