Peace Negotiations

Answer AND Explanation:
<u>FACTORS THAT CAUSE GENETIC VARIATIONS</u>
- Crossing over. At the chiasmata during prophase I of meiosis, breakage may occur and exchange of genetic information may take place. New gene combinations which result in variations.
- Independent assortment. The arrangement of homologous chromosomes at the equator of the spindle during metaphase of the first meiotic division is random. These homologous chromosomes segregate into different daughter cells which contain different genetic combinations which brings about variation
- Fertilisation permits parental genes to be brought together in different combinations. This is the cause of variations in members of the same family.
- Mutation is the spontaneous change in the genetic makeup of an organism. These changes may be inherited by the offspring therefore beginning variation.
En 1990 se inauguró definitivamente el Proyecto Genoma Humano calculándose quince años de trabajo. Sus objetivos principales en una primera etapa eran la elaboración de mapas genéticos y físicos de gran resolución, mientras se ponían a punto nuevas técnicas de secuenciación, para poder abordar todo el genoma.

Answer:
Even though they are the same temperature, the metal will feel colder than the wood because of the thermal conductivity of the metal, compared to the wood. Metal is a good conductor of heat, hence it sends away the heat. On the other hand, wood is a poor conductor of heat, hence releases the heat too slowly.
