It’s blurry but imma assume the last one
Carbon dioxide emissions lead to the increase of the planet's temperature, contributing to the greenhouse effect. That is so because it causes damage in the ozone layer, a barrier from the sun rays. Once there is a damage, through it the sun has a deeper contact with humans causing diseases. Once the temperature raises, all the cycles suffer with its influence (water cycle of evaporation, rain, etc), The CO2 concentration in the air causes pollution and respiratory diseases and affect the plants photosyntesys and so on.
Answer:
E) a natural mutagen.
Explanation:
Aflatoxin is a toxin byproduct produced by the fungi especially Aspergillus molds which grows attached to the roots of various crops like the peanuts, wheat and many others.
The aflatoxin is considered a carcinogen and a mutagen as it causes certain changes in the structure of DNA. The aflatoxin mainly affects the liver and causes a mutation in the genes of the liver and since the aflatoxin is produced naturally by the molds, therefore, is considered a natural mutagen.
Thus, option-E is correct.
Answer:
Regulated gene expression is crucial to the proper growth & survival of an organism and cannot be over-emphasized. Without it, the genetic code of a chromosome is the equivalent of a computer data file without the appropriate application to run it.
