Aneuploidy can result in the final daughter cell if the spindle fibers fail to pull a chromosome toward the pole as in case of non-disjunction.
Explanation:
Aneuploidy is a condition which arises when one or more chromosome is missing in the final daughter cells.
Non-disjunction refers to the failure of chromosomal or chromatid segregation or separation during cell division. This results in erroneous meiosis or mitosis leading to the formation of final daughter cells or gametes with an extra or missing chromosome. This condition is aneuploidy.
Failure of separation or segregation of:
- Homologous chromosomes occur in Anaphase I, affects four daughter cells.
- Sister chromatids during Anaphase II, affects two daughter cells
This failure of separation leads to aneuploidy chromosomal abnormalities like monosomy, trisomy, etc which can cause diseases like Down’s syndrome, Turner’s syndrome etc.

The correct answer is this one: "A.When actin filaments are pulled toward the center of the sarcomere, the fiber shortens." The statement that accurately describes the way in which a muscle moves is when actin filaments are pulled toward the center of the sarcomere, the <span>fiber shortens</span>
Transports salt into the ocean.
Basically, a droplet of water falls, freezes, and is blown back up over and over and over again without hitting the ground. Each time it keeps accumulating more water droplets that keep freezing to the growing hail stone. That's how all hail is formed. When the hail stone is too big for the winds to keep blowing it back up again, it falls. The stronger the updrafts, the bigger the hail will get before falling to the ground. That's why it takes a pretty powerful storm to make a big hail stone -- the winds have to be strong enough to blow an almost baseball-sized piece of ice back upward again for it to keep growing.
