To form a platelet plug, platelets are attracted to the damaged vessel, and then platelet ADHESION. It is fundamental during vascular injury.
<h3>What are platelets and platelet adhesion?</h3>
Platelets are specific types of blood cells that act in order to help blood clot.
Platelet adhesion is a fundamental cellular mechanism that occurs due to situations of vascular injury.
During this process (platelet adhesion) platelets bind via cell membrane receptors to both cell and extracellular matrix.

Answer:
With nuclear fission, a large atomic nucleus (such as a uranium nucleus) breaks apart into smaller nuclei, and energy is released. With nuclear fusion, small atomic nuclei (such as hydrogen) join to become larger nuclei, and energy is released. Fusion of hydrogen releases much more energy than any other type of either fusion or fission. Note that the dividing line between heavy nuclei and light nuclei is the iron nucleus, which is at the perfect point of nuclear stability, so that neither fusion nor fission of iron nuclei would release any energy.
A warm spell during the Ice Age gave early humans a route out of Africa 20,000 years earlier than thought, say scientists who've uncovered a prehistoric tool kit in Arabia. ... Seas in the region would still have been at relatively low, Ice Age levels, making for shorter crossings.

Independent assortment
Explanation;
According to the law of independent assortment; During meiosis homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other.
This process results to the formation of gametes that have a unique combination of chromosomes.
