Nicholas is a college student who must present a summary of a recent chemical discovery to his class. What pair of sources would
alina1380 [7]

Answer:

Option D,  a research paper published in an academic journal and an approved PhD dissertation

Explanation:

Nicholas must present her discovery with back up of strong literature review. This literature review must include papers published in good journals and only approved research dissertation.  

An internet blog, news article and college level textbook are not considered as an approved study. These are not reviewed or approved by any peer group or associations.  

Good papers of any good journals are reviewed and examined thoroughly by the peers and thus they can be used as a backup of any study.  

Hence, option D is correct

Which statement is the correct contrast to the mistaken idea of spontaneous generation?
kramer

All organisms reproduce either sexually or asexually is the correct contrast to the mistaken idea of spontaneous generation

C . all the organisms reproduce either sexually or asexually

The essential character is offspring is while mother supply is the only solid substrates. The reproduction also takes place by either the egg of the mother or the sperm of the father and began to grow when it is stimulated. Spontaneous generation is defined as the living creature that could arise from nonliving matter.

Cells assemble carbohydrates through dehydration synthesis which means a(n) what molecule is removed when the monomers are bonde
mr_godi [17]
The process for connecting two monomers together is called dehydration synthesis. Dehydration means “removal of water” and synthesis means “to join together”. So in this process, two monomers are covalently bonded by the removal of a water molecule. Each organic monomer has a hydroxyl group on one side and a hydrogen on the other. When two monomers line up side by side, they will have these two functional groups facing one another. The H and the OH will break off of their respective monomers and bond forming a water molecule. This is the dehydration part of the process. Each monomer now has a carbon atom that needs to covalently bond with something, so they bind to each other forming a polymer. That is the synthesis part of the process.

How could different nucleotide sequences result in the same amino acid<br> sequences?
vladimir1956 [14]

Answer:

There is more than one codon that can specify most amino acids, therefore you never know which one was used for a particular protein, unless you can look at the DNA or RNA sequence.
