Nucleic acids / aka nucleotides
Answer:
e. None of the above
Explanation:
For me as a Researcher, the reason could be increased Concentration of your DNA sample which you are using as your template. Try to decrease the concentration of DNA (up to 100 ng per reaction is enough and can increase up to 200 ng). so the reason for getting non specific bands is increase concentration of DNA which results in non specific amplification and also degradation of DNA in the reaction which you can see in your gel electrophoresis results.
i always corrected my results using the same technique that is lowering the concentration of DNA between 100 and 200 ng per single reaction of PCR.
Answer:
The correct option is B.
Explanation:
Lichens is regarded as a mutual relationship between a mycobiont and photobiont, the relationship is targeted at enhancing their survival in extreme environments. The mycobiont is a fungal while the photobiont is usually a green alga or a mycobacterium. Each of the organism has their specific tasks; the mycobiont provides suitable habitat for the photobiont while the photobiont provide energy for the whole system.
The 4th one. Maintaining body temperature and cooling down
What types of factors should be investigated?
D. Both abiotic and biotic factors in their ecosystem
Abiotic factors are non-living parts of an environment, while Biotic factors are the living parts of an environment. That being said, you should investigate both when the population of jellyfish show a sharp decline, in order to find out the cause in the decline of jellyfish.
