Sir Charles Sherrington’s observation has provided evidence for the existence of synaptic gaps in which this is the minute space provided in between of the target cell and the cell membrane of the axon terminal. This could be seen from his observation where the impulses took unexpectedly long time to travel a neural pathway.

The nitrogenous bases guanine and adenine are A. purines. B. a phosphate group. C. pyrimidines. D. a sugar group.
AleksAgata [21]

Answer:

The nitrogenous bases guanine and adenine are A. purines.

Explanation:

Adenine and guanine are purines, whereas the other two bases in DNA (thymine and cytosine) are pyrimidines.  The main difference between purines and pyrimidines is the number of rings that the base has: purines have two rings while pyrimidines only have one ring.  

In addition, phosphate group and sugar group cannot be the answer to this question because these two elements in addition to a nitrogenous base makes up a nucleotide.

Hope this helps!

Identify two general ways chemical mutagens can alter dna.
gavmur [86]
1) compound mutagens can go about as base analogs 
Analogs are perceived by DNA polymerase and consolidated into DNA set up of nucleotides and after that reason change by base-matching in a way that varies from the undifferentiated from nucleotide. For instance, 5-BrdU can be consolidated inverse An amid replication and after that combine as a C amid the following round of replication, making a TA CG change. 
2) substance mutagens can synthetically adjust base. 
Compound adjustment of bases changes their base-blending properties to such an extent that an altered purine will base-match with the wrong pyrimidine and the other way around. For instance, EMS is an alkylating operator that proselytes guanine to O6-methylguanine, which base-sets with T to make a GC to AT progress
