The mushroom Amanita phalloides contains a peptide called alpha-amantin. When ingested, this toxin kills cells, especially liver cells, by blocking the function of RNA polymerase. The most immediate effect of this toxin is to prevent and the production of .
a) translation, mRNA
b) transcription, mRNA
c) transcription, protein
d) replication, DNA
e) translation, protein

b) transcription, mRNA

Explanation:

Transcription is a process in which mRNA is produced from DNA. RNA polymerase is the enzyme that is required to make mRNA in the transcription process.

So as a peptide called alpha-amanitin kills cells by blocking the functioning of RNA polymerase therefore mRNA will not be produced because the transcription process can not proceed without RNA polymerase. So as mRNA will not produce, no protein will be produced to support the cell's functioning. So the cell will die.

Therefore the toxin will prevent transcription and the production of mRNA.

answer; i believe the correct answer is (sporophyte);

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
