Answer:
This composition of nucleotide given in the question do not obey the chargaff"s rule.
Explanation:
According to chargaff"s rule the total number of purine bases will be same to the total number of pyrimidine bases that is
Adenine+Guanine=Thymine+Cytosine
But here the above quation is not maintained because according to the question A+G=49%
and T+C = 51%.
Such DNA is replicated by rolling circle model.
Answer:
C

Explanation:
The all or none response means that if a muscle contracts, it will contract completely. Thus implying the all or none law which states:
The potential of a response of a muscle fiber or nerve cell is independent of the potential of the stimulus. If a stimulus is more than a certain critical value it will trigger muscle fiber or a nerve. Most importantly resulting in either an all-or-none response thus reducing possibility of any information loss.
Answer:
The evolution of the species might occur due to the change in the environmental conditions and the mutation in the organisms. The organism that can adapt in the environment will survive better.
The lizard species is present in the Ethiopian biogeographical region but now its two living species is in Neotropical biogeographic region and three species is in Australian biogeographic region. This might possible due to the fact that Neotropical and Australian lineages might have the common ancestor that were earlier originated in the Ethiopian region. The continental drift might have occur that breaks the Ethiopian biogeographical region and the species are present in the different island.
