x-rays,sunlight,toxic chemicals
The temperature heats the rock and breaks it (erodes).
Aneuploidy mutation causes a change in the number of chromosomes. Aneuploidy occurs during cell division when the chromosomes do not separate properly resulting in a change in the number of chromosomes.
This is the theory because all femle ova have female chromosomes.. Sperm have male and female chromosomes. If the sperm containing female chromosomes then nothing changes during fertilization. If male chromosomes, then changes take place to cause the cells to produce a male. There is scientific theory that this may be a cause of homosexuality in that the changes do not occur as expected. But this is only theory. --- They don't necessariy start as female, but they do have female organs. It is the presence of chemicals (due to Y chromosome) that forms the male organs from the female organs later on.
The Earth's tilt and orbit cause seasonal temperature changes.
possibley, not too sure. Sickle cell is usually passed down though
When a segment of a chromosome breaks away and joins a non-homologous chromosome, it is called a translocation. This can lead to gene disruptions and potentially cause genetic disorders.
Temperature, rainfall, sunlight, humidity, pressure, etc
Chromosomal disorders are caused by abnormalities in the chromosomes.
Factors that can cause a shift in equilibrium include changes in concentration of reactants or products, changes in temperature, changes in pressure (for gases), and the addition of a catalyst. When these factors are altered, the equilibrium position will shift in order to minimize the effect of the change and restore equilibrium.
factors that cause weathering are erosion and water
when you dont take care of your hair it breaks off. if you don't wash it regularly it will break off
If it had more chromosomes it will cause to down's syndrome
