Predict the effect of increased levels of carbon dioxide on the rate and depth of respiration:

Normal blood is at least 50% saturated with oxygen.

This white blood cell produces antibodies that attach to microorganisms:

This white blood cell becomes a macrophage and is most effective with chronic bacterial infections:

This white blood cell destroys parasitic worms by releasing toxic chemicals onto its membrane:

White blood cells are capable of leaving the blood stream and following chemical trails to destroy microorganisms in our tissues.

Deoxygenated blood enters the lungs in the R and L Pulmonary arteries and leaves as oxygenated blood in the R and L Pulmonary veins.

Keep.  Suppose the nitrogenous base sequences below are DNA.  Simulate transcription by creating a mRNA sequence complementary to the lower of the DNA sequences.  Do not transcribe the promoter.   5ʹ  A T A T A T A T || C G T G T G T A A C A C T G A T G C T G A C G T G T   3ʹ   3ʹ  T A T A T A T A || G C A C A C A T T G T G A C T A C G A C T G C A C A  5ʹ   Blah  

White blood cells are capable of leaving the blood stream and following chemical trails to destroy microorganisms in our tissues.

Keep this one or the one above.  Assume the letters below represents a segment of nitrogenous bases on DNA.  Suppose this segment will function as a location where a primer will be placed. 3′  A  G  T  C  T  G  A  G  T  C  A  T  G  5′ In the space provided, write the base sequence of the primer.
