Rosa drew a flow chart of the carbon cycle.

ioda

Answer:

X: Producers undergo photosynthesis;

Y: Decomposers return carbon to the soil and release waste

Explanation:

Producers, for example, a clover, will take the CO2 in the atmosphere and use it in photosynthesis to turn it into nutrients, then the consumers, for example, a deer, will eat the producer to gain nutrients. After the consumer dies, the decomposer, for example, fungus, will eat away at the consumer, releasing CO2 into the atmosphere. Then the cycle keeps going.

Indicate the direction in which RNA polymerase moves as it transcribes this gene. Indicate the direction in which RNA polymerase

anastassius [24]

Answer:

RNA polymerase moves along the template strand in a 3'-to-5' direction.

Explanation:

RNA polymerase is an enzyme involved in the synthesis of an RNA molecule from a DNA molecule. The process of synthesis of an RNA molecule is known as transcription which takes place in the nucleus of eukaryotes.

The DNA strand which is transcribed into the RNA molecule is known as template DNA and run from the 3'to 5' end.

The RNA polymerase enzyme binds to the promoter region which initiates the reaction. The RNA polymerase enzyme forms the RNA molecule in 5'to 3' direction by adding new nucleotide at 3'end, therefore, it has to move on the template strand with 3' to 5' direction.

Thus, the selected option is correct,
