The process called menstruation.
Answer:
The presence of an additional chromosome
Explanation:
Look at "pair" 21. See how there are THREE chromosomes instead of TWO? Normally, there would only be two chromosomes in each pair but this karyotype shows a trisomy (see def. below) of the 21st pair. This was caused by a nondisjunction mutation of the 21st pair. The is also the karyotype of a person with Down's Syndrome.
Definition of Trisomy:
A condition of the presence of three chromosomes in a pair instead of two. This normally causes developmental irregularity.
Answer:
mitosis
Explanation:
The cellular process that enables the cells to grow and develop into tissue is mitosis.
Mitosis involves the division of the vegetative cells of the body and is important for the growth and development of organisms as well as in the healing of wounds or the replacement of damaged cells/tissues.
<em>Hence, in treating burns and other types of skin injuries, the cells of the skin are stimulated to divide rapidly by </em><em>mitosis</em><em> so as to replace the damaged cells due to the injury. By doing so, the injured area heals.</em>
