Where is the centrome located on the chromosome and what it is role ? 1.) It is not exactly at center, and it attaches to spindle fibers during cell division.
2.) It is exactly at the center, and it attaches to spindle fibers during cell division.
3. It is exactly at the center and it is responsible for making the q-ark longer than the p-arm.
4.) It is not exactly at the center, and it always the p-arm longer than the q-arm.

then that particular organisms become extinct.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
