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.

1.) What gives water all its properties? 2.) What type of bond joins H2O to another H2O and forms cohesion? 3.) What property of
Yuri [45]

Answer:

1. polarity

2. hydrogen bonding

3. High heat capacity

4. Adhesion

5. polarity

6. surface tension

7. high heat vaporization

8. hydrogen bonds form a rigid and stable network

9. Water is a polar substance and fat is a nonpolar substance.

10. Cohesion

Explanation:

Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.

The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.

High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.

When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does  not interact with fat because like dissolves like.

In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.
