Answer:
All the arteries except pulmonary artery carry pure blood..it is so because blood flows with a high pressure and speed And because Arteries are situated deeper under the skin have thick-walled with Narrow lumen(cavity) and pulmonary artery carries deoxygenated blood i.e without oxygen..
Explanation:
lumen means Empty space within an object(solid)

The first step to DNA replication is to unzip the double matrix which also means that they will break the double matrix.
Coordination is the working together of various organs of the body of an organism in a proper manner to produce appropriate reaction to a stimulus.
Control is the power of restraining and regulation by which something can be started, slowed down or stopped
Based on the genotype of AB blood, the a and b genes are codominant.
Since both A and B antigens are equally prevalent on red blood cells, the A and B genes are related in a codominant manner.
<h3>What is gene?</h3>
- A gene is a fundamental building block of heredity and a DNA sequence of nucleotides that codes for the production of a gene product, either RNA or protein.
- DNA is initially transcribed into RNA during gene expression.
- The RNA may execute a specific function directly or may serve as an intermediary template for a protein.
<h3>What is codominance?</h3>
- In terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person.
- Animals that exhibit codominance include roan cattle and speckled chickens, which have alleles that express both red and white hair as well as both black and white feathers.
- Plants also exhibit codominance.
