It would mix faster in the hot water because it moves free and more faster with a bunch of water vapor coming off of it
Answer:. Nondisjunction during meiosis I in either the male and female gamete
The failure of homologous chromosome to separate at mitosis, or failure of sister chromatids to separate at Anaphase of meiosis I or ii is called non-disjunction.
In this cell division anomaly the unsegregated chromosomes are separated into cells as single chromosomes, therefore extra copies are therefore inherited.This result is one of the cell having an extra copies of chromosomes than others( chromosomes 21.
If this extra chromosome copies is segregated into a sperm or egg, the resulting zygote cells will have extra copy as chromosome 21, and hence Down syndrome.
→It is more common in Meiosis 1 than ii,because of longer duration of the first stage of division than meiosis ii,given rooms to errors.
→Most common in women(with age increase) than men because of exchange of telomeres in them,which worsen with age. Their Meiotic mechanism which weaken with age, and more prone to errors compare to men,
Explanation:
Explanation:
The tropical rainforest is made up of a dense network of trees, shrubs and vegetation.
This zone on earth is the most biodiverse on the earth surface. It receives the highest insolation of all places on earth and so radiant energy here is very high.
- Due to this, the net productivity is very high.
- This implies that a wide range of food is available to support the diverse organisms.
- Also, the wet and dry seasons provides a very conducive weather for most organisms to survive.
Tundra and deserts have low precipitation and the conditions are very harsh.
Phylogentic Trees are also called Evolutionary Trees. They're also a part of a group called Taxa.
