Answer:
1. Head, neck, upper limb, thorax - super vena cava - top of the right atrium.
2. Lower limb - inferior vena cava - bottom of the right atrium.
Explanation:
The Heart pumps the oxygen-rich blood to the different parts of the body to Otake oxygen and nutrients to these organs and then takes the oxygen-poor blood returns from the body to the heart.
The two major vessels that return oxygen-poor blood to the heart are 1. superior vena cava (SVC) that drainages Head, neck, upper limb, thorax and terminate at top of the right atrium, and 2. inferior vena cava (IVC), Lower limb and terminate at bottom of the right atrium.
1. Head, neck, upper limb, thorax - super vena cava - top of the right atrium.
2. Lower limb - inferior vena cava - bottom of the right atrium.
Answer:
DNA polymerase
Explanation:
DNA polymerase enzyme catalyses the reaction of adding nucleotide to growing complementary daughter strand of DNA in the direction of 5' → 3' during elongation in the process of replication. This process requires energy which is taken from nucleotides with three phosphate groups in their backbone similar to ATP (adenine triphosphate)
DNA Replication is when DNA multiplies and make exact copies of itself as part of gene transfer.
Here are the 3 parts of the cell theory:
1. Cells are the basic building blocks of any living things.
2. Any living thing is composed of more than 2 cells.
3. New cella arise from the old
