Answer:
The correct answer would be option B.
Sinoatrial node is also known as heart's pacemaker as it controls the heart rate.
It consists of cluster of cells in upper region of the right atrium. These cells generate electrical signals which are passed onto atrioventricular node.
It is the cluster of cells which is located at the centre of the heart.
It passes and slows down the electric signals to the ventricles.

The smallest unit among the options is mm(Millimeters). Thus, option a) is the answer.
The smallest unit among the options is "a) mm," which stands for millimeter. It's a metric unit of length that is one-thousandth of a meter (1/1000). Millimeters are commonly used for precise measurements, especially in fields like engineering, science, and manufacturing, where accuracy is crucial.
Centimeters (cm) are larger than millimeters, with one centimeter being equal to 10 millimeters. Meters (m) are even larger, being the base unit of length in the metric system. Kilometers (km) are the largest unit among the options, equivalent to 1000 meters.
In summary, when comparing the given options, millimeters are the smallest unit of length, followed by centimeters, meters, and then kilometers, with each subsequent unit being larger by factors of 10.
The correct option is : a) mm.

Sister chromatids line up at the equator of the cell during the metaphase stage of cell division. This arrangement is essential to ensure each new cell receives an exact copy of each chromosome. The next stage, anaphase, involves the separation of these chromatids.
The sister chromatids line up at the equator of the cell during the metaphase stage of cell division, whether it is mitosis or meiosis. The stage where sister chromatids align in the middle of the cell is integral to the process as it ensures that each new cell will receive one copy of each chromosome. In the next phase, anaphase, these chromatids are separated and drawn to opposite ends of the cell. Thus, the correct answer to your question is (a) metaphase.
