Answer: Cohesion
Explanation:
The cohesive attraction or cohesive forces is the action or property of like molecules which stick together.
It can be intrinsic forces that can be caused by the structure and shape of water. This allows the water molecules to stick to each other.
Due to this phenomenon of water it has a spherical shape and it flows in a liner motion.
Hence, the force that is present between two water molecules is cohesion.
Errors can occur when the chromosomes segregate into the gametes during meiosis resulting in egg or sperm with too many or too few chromosomes. As a result, fertilised eggs and the ensuing embryos may have trisomy (an extra chromosome of a particular pair) in each cell or monosomy (one chromosome fewer in each cell).
<span>The Human Genome Project had a very negative effect due to development
in technology and academic rivalry. With knowledge came bitter rivalry and with
technology came the tendency to become God. These angles greatly created
negative impact about this project. The experts tried to create human clones,
tissue engineering etc. The scientists
tried to analyze a person and get rid of any future disease that might attack
them. Some people feel this is good while others feel that it is like
distorting the natural process. </span>
