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.
D) Increase in temperature.
When we are too hot, blood vessels supplying blood to the skin can swell or dilate (vasodilation). This allows more warm blood to flow near the surface of the skin, where the heat can be lost to the air.
Answer:
The correct answer is - All of the above
Explanation:
Food is produced at every part of the earth as it may be found even in the parts that are darkest at night or at the part of ocean. Communication between mates can be done by signals that may sent to show interest in mating, Camouflage is the way to escape or hide by use of the light that may momentarily distract predators as it can camouflage the underbelly of the fish by lighting it up the same color of as the sea surface to make it invisible.
