<span>When sunlight excites electrons in chlorophyll the energy of the electrons increases. After the electrons gain energy they are taken by carrier molecules from chlorophyll to other molecules.</span>
Answer: When the DNA collected on the crime scene is being analysed in the forensic lab, the results will be inconclusive, because error in DNA transcription, particularly in mRNA encoding leads to inheritable phenotype change by reprogramming the transcriptional network, without changing the DNA. Transcription errors are brief with no long-term consequences. Due to mRNA being short-lived and the erroneous proteins are degraded. A decrease in transcription accuracy triggers cellular identity change.
Explanation: This is called epimutation, a heritable modification that results in the change of gene expression, but not the DNA sequence. Epimutation is not associated with DNA mutation, but is associated with the loss or gain of DNA methylation or other heritable changes of the chromatin.
Answer:
The polar bear is an animal which is prevalent in the arctic region of the world which is characterized by very cold icy climate.
They adapt to these climatic conditions by maintaining a body temperature of 37°C through its thick fur and tough skin. It also has an insulating fat layer (adipose tissues) which is very thick.
This insulation helps in keeping the animal very warm in extreme temperatures.
Explanation:
From the allergy of the sun. Because of a condition called Polymorphous light eruption that causes a spottyvree rash.
Answer:
The positive effect of the application of a GPS over a compass is that one can get success in getting to his or her desired location. A GPS can inform about the exact location, and when it is combined with a map, it makes the person reach straight to where he or she desires to go
