The Pulse point with the greatest
amplitude is the Common carotid artery and the pulse point with least amplitude
is dorsalis pedis artery. Pulse is the pressures that alternate surges
(expansion and recoil) in an artery that happens with each contraction and relaxation
of the left ventricle.  So when the dorsalis
pedis had this low amplitude the BP decreases and smooths out when the movement
of the blood go farther from the due to elasticity of arteries. Then there is
an elevation of blood pressure when you exercise because the greatest amount of
cardio output and peripheral resistance. 
 
        
             
        
        
        
The correct answer is Mollusks, Echinoderms, Chordates, and Annelids.
This is basically how evolution works, at a certain point in the past,
there was a transitional organism that eventually developed into
roundworms and the other part of his species that was exposed to other
things evolved into other transitional organisms who evolved eventually
into these 4 groups.
        
                    
             
        
        
        
Answer: alternative D.
Explanation: For the DNA to have the double strand structure, it is necessary to copy the sequence of the existing DNA strand in a complementary sequence of nucleotides, forming hydrogen bonds between them. The mRNA also uses this strategy when reading the DNA strand during the transcription, in order for the translation to begin. 
 
        
             
        
        
        
Your answer is B.
It's called an occluded front where the cold air meets the warm air underneath it. Hot air rises over cold air. :) Hope this helps you.
