Explanation:
Compare and contrast two mechanisms for transcriptional termination in bacteria.
(rho)p-dependent termination: requires rut (rho utilization site), rho protein binds, moves towards 3' end, DNA encodes GC rich for stem loop, RNApoly pauses, rho protein catches up and separates RNA-DNA hybrid
(rho)p-independent termination: Uracil-rich sequence causes RNApoly to pause, stabilized by NusA near open complex RNA exit, UA bonds to weak to hold, DNA-RNA hybrid dissociates AKA intrinsic termination

The gravitational force would increase, as the mass is increasing.
Answer:
D. mass feeder
Explanation:
A) suspension feeder
B) fluid feeder
C) deposit feeder
D) mass feeder
<em>Suspension feeder requires capturing of food that are suspended in water through the use of specialized organs.</em>
<em>Fluid feeding involves feeding on liquid (such as blood) emanating from other organisms.</em>
<em>Deposit feeding involves feeding on sediments</em>
<em>Mass feeding involves ingestion of scraps of different food materials.</em>
Hence, the correct option is D.
