Answer: metaphase
Explanation:
The failure of sister chromatids to separate during meiosis II occurs in metaphase stage. This is called as nondisjunction, this will affect the normal distribution of chromosomal material to the daughter cells. This will result in a problem called aneuploidy. There are abnormal number of chromosome per cell.
The sequential events in the Arctic ecosystem feedback loop are: Global temperature increases → permafrost thickness decreases → methane increases → global temperature increases. It is harmful to the Earth.
The Arctic ecosystem is a feedback loop because the warmer the temperatures, the less sea ice (permafrost) is observed.
The Arctic ecosystem feedback loop is a dangerous phenomenon because it accelerates global warming.
Permafrost refers to ice ground that remains completely frozen (0°C) for at least two (2) or more years straight.

Because the small area of that desert provides the provisions the organism needs. They adapt to their climate, so as long as the desert keeps its supply, the organism will stay
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
