Answer:1.c 2.d 3. d
Explanation:
The DNA hyperchromic effect can be defined as the absorbance of radiation or light by the nitrogen bases of DNA. This phenomena is effective when the DNA is in single stranded condition. For observing the hyperchormic effect the DNA is required to be denatured at high temperature or by increasing the level of pH.
The two strands of the DNA when get separated the absorbance of the DNA solution also increases. This results due to reduction in the base-base interaction and hence, increases the absorbance of light like UV by the bases.
-20 is the answer it’s pretty simple
Sun is the main source of light for the plants to function photosynthesis
I do not know how to work the problem out at the given time. However, If you are answering a multiple choice answer test, this is the answer.
