It is also known as Trisomy X or Poly X syndrome. This occurs when there is a presence of an additional X chromosome and it is a syndrome caused by abnormal formation of an egg/sperm cell or during embryonic formation.
Females with this condition are usually than average but there is no much evident unusual physical features.
Males with an additional X chromosome are said to have Klinefelter's syndrome with the XXY genotype.
Explanation:
Males with an additional X chromosome are said to have Klinefelter's syndrome with the XXY genotype. They appear to be quite tall and lean, and could have learning disabilities and problems with reproduction, but they are developed differently.
Klinefelter syndrome usually takes place when reproductive cells (eggs and sperm) are produced as a natural event. An error throughout the cell division termed nondisjunction results in an unusual set of chromosomes in a fertility cell.
Rhythm - it is considered to be the principle of alternation of elements. it means to reuse certain elements in the design. it deals with unity, consistency.
Rhythm can be divided into three main type
- Regular
- Flowing
- Progressive
Repetition is considered to be sense of cohesiveness between the elements in a design. it enhances the hierarchy within the design
Influence of Earth's physical factor on population density is explained below:
<u>Explanation:
</u>
Earth's physical factors influence the population density in such a way that it becomes the key determinant for people to choose where they should reside.
earth has both extremes of surviving in a particular area of non-survival areas were humans cannot survive.
People most probably choose the areas of survival based on their basic needs the support their survival (for example source of food, water resource, climate conditions, availability of life-supporting resources, etc)
When population increases in an area the birth rate also increases with a greater number of young people and age structure becomes a pyramid representation with young people existing more than old ones.
