The statements that correspond to cellular respiration are:
2) CO2 diffuses passively out of the cell.
6) O2 is pumped in and forces CO2 out
Cellular respiration in animals produces carbon dioxide as waste products. Cellular respiration is presented like this:
oxygen + glucose → energy + carbon dioxide + water
Answer:
B -the absence of the inducer, but not in its presence
Explanation:
In positive repressible regulalor mechanisms transcription of the structural gene(s) occurs in the absence of the inducer because proteins are normally bound to the pertinent DNA segment. when an inhibitor is bound by the inducer, it is prevented from binding the DNA. which will the stops the activation and transcription of the structural genes.
Example of positive repressible regulator is Activator .
Regulating the rate of transcription is a mechanism of gene regulation leading to the productionn of more than one protein product from a single gene.
This would be a relation ship of either mutualism or symbiosis
