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

What statement correctly describes the relationship among endocrine glands, target cells, water-soluble hormones, and lipid-solu
9966 [12]

Water-soluble and lipid-soluble hormones that bind to target cells are secreted by endocrine glands.

The interaction between endocrine glands, target cells, water-soluble hormones, and lipid-soluble hormones is accurately described by the aforementioned sentence.

<h3>What functions and how does the endocrine system operate?</h3>

The level of hormones in your blood is regularly monitored by your endocrine system. In order to transmit the message, hormones send their messages by locking into the cells they intend to reach.

When your hormone levels increase, the pituitary gland signals other glands to stop manufacturing and releasing hormones. The pituitary gland has the ability to tell other glands to manufacture and release additional hormone when levels fall below a certain threshold.

Homeostasis is a process that functions similarly to your home's thermostat. Almost every physiological process is impacted by hormones, including:

  • Metabolism
  • Growth & development.
  • Emotions & mood.
  • Fertility & sexual function.
  • Sleep.
  • Blood pressure.

Choose all the pieces of individual evidence.
faust18 [17]
Criminal evidence is any physical or verbal evidence presented in court to prove a specific crime. Evidence can take different forms and can be used by the accused to prove innocence. Admissible evidence, moreover, is the use of testimony (oral or written such as affidavit), exhibits (physical objects), documentary material or demonstrative evidence ( in the form of representation of an object including photos, x-rays, videotapes, movies, sound recordings, diagrams, forensic animation, maps, drawings, graphs, animation, simulations or models). All are presented before a judge or jury to prove a point or element in a case. In the choices above, six of them can qualify as individual evidence except numbers 3. Number 8, however, is questionable since it has incomplete description as to where and how is the paint was chipped.
