A conservative replacement (also called a conservative mutation or a conservative substitution or a homologous replacement) is an amino acid replacement in a protein that changes a given amino acid to a different amino acid with similar biochemical properties (e.g. charge, hydrophobicity and size).
Catastrophism was largely replaced by uniformitarianism and neocatastrophism; Cryptoexplosion craters, now discarded in favour of impact craters and ordinary volcanism. Flood geology replaced by modern geology and stratigraphy; Neptunism replaced by plutonism and volcanism; Granitization, a discredited alternative to a magmatic origin of granites
Amino acid replacement is a change from one amino acid to a different amino acid in a protein due to point mutation in the corresponding DNA sequence. It is caused by nonsynonymous missense mutation which changes the codon sequence to code other amino acid instead of the original.

A research design that involves multiple measures of the same variable taken on the same or matched subjects either under different conditions or over two or more time periods. [ 1 ] Paired t-test , Wilcoxon signed-rank test
In AP Research students design, plan and conduct a year-long research-based investigation on a personally-chosen subject. The assessment culminates with a 5,000-word academic thesis paper, as well as a public presentation. Students must obtain a final score of 3 or higher to be able to receive AP certification. [1] As of the 2017–18 school ...
The dreaded “Research Project” is a standard hurdle for most AP Programs. Rightfully so, being that many college courses require such publications to validate your existence. This new approach to constructing a scientific document, is far more authentic and interesting.
This course is designed for students who wish to pursue an interest in the life sciences. The College Board recommends successful completion of high school biology and high school chemistry [2] before commencing AP Biology, although the actual prerequisites vary from school to school and from state to state.
