Specialized tissue on the wall between the atria. Electrical impulses pass from the pacemaker (SA node) through the _______ and the atrioventricular bundle (bundle of His) toward the ventricles.atrium (pl. atria)One of two upper chambers of the heart.capillary<span>Smallest blood vessel. Materials pass to and from the bloodstream through the thin walls. They have walls that are only one endothelial cell in thickness. This delicate, microscopic vessel carries nutrient-rich, oxygenated blood from the arteries and arterioles to the body cells. There, the nutrients are burned in the presence of oxygen (catabolism) to release energy.
At the same time, waste products such as carbon dioxide and water pass out of the cells and into these blood vessels. Waste-filled blood then flows back to the heart in small venues, which combine to form larger vessels called veins.</span>carbon dioxideGas (waste) released by body cells, transported via veins to the heart, and then to the lungs for exhalation.coronary arteriesBlood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle.deoxygenated bloodBlood that is oxygen-poor.diastole<span>Relaxation phase of the heartbeat.</span>

In order, they would be 2, 4, 3, 1, 5.
Answer:
yes
Explanation:
because the only thing that is changing is the number of cells, mitosis causes cells to split and multiply forming organisms
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the chart referred to in the question. However, what appears to be the case is that the three nitrogenous bases represent codons (and the missing chart is the codon chart). The mutation that has the potential to cause more damage will be the one that would change the amino acid formed from the codon change.
A. CAU to CAC: The codons CAU and CAC both form the amino acid histidine and thus is not expected to cause a major damage.
B. UGU to UGC: The codons UGU and UGC both form the amino acid cysteine and thus is not expected to cause a major damage.
C. UCU to UUU: <u>Codon UCU forms the amino acid serine while the codon UUU forms the amino acid phenylalanine</u>. Thus, this eventual change in the amino acid formed has the potential to cause a major damage and thus option C is the correct option.
NOTE that a codon is a sequence of three DNA/RNA nucleotides that corresponds to a single amino acid.
