A closed circulatory system is present in organisms with a circulating body fluid that is distinct from the fluid that directly surrounds the body's cells.
<h3>What is the circulatory system?</h3>
The circulatory system is an organs system that works to carry out blood cells to all cells in the body.
The circulatory system is fundamental for transporting oxygen and nutrients to all cells of the body.
A closed circulatory system is a special organ system where the blood cells are not circulating in body cavities.

This process is called DNA Replication. Replication is essential/needed with DNA and when the cell divides into two parts, the two daughter cells have to have the same genetic information. Replication is needed for this genetic information to be copied.

Answer:
A biochip or DNA chip or DNA microarray is a slide that contains the different fragments of DNA . The DNA microarray technique is used to study the expression level of various genes simultaneously. For this the researcher:
A. Attach the fragments of DNA about 500 to 5,000 bp that are produced by the controlled growth of the nucleotides by providing the narrow beam of light and synthesised by the PCR technique on to the slide in the form of dots or spots.
B. In dots, the reporter oligos or probes are attached which are used to hybridize the cDNA to the microarray. The cDNA is labeled with the fluorescent molecules called fluorophore.
C. After hybridization, the probe-target hybridization is detected by placing the washed array in the confocal fluorescence microscope which observes the pixel and helps calculate the fluorescence intensity.
The answer is Starch. Hope this helped!
