The reticular formation . A) sets the rate of respiratory movements
B) contains nuclei and centers that regulate vital autonomic nervous system functions
C) relays somatic information to the ventral posterior nuclei of the thalamus
D) regulates heart rate and force of contraction, and distribution of blood flow
E) relays information from the spinal cord, the red nuclei, other midbrain centers, and the cerebral cortex to the vermis of the cerebellum

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)

The illustration shown is an ovum, a female sex cell. a mutation in this cell may be passed to the woman’s offspring during a) birth. b) mitosis. c) dna replication. d) sexual reproduction

What does the positioning of transcription factors determine?
