Answer:
<h2>Two normal cells, n and n;</h2><h2>One cell lacks chromosomes : n-n</h2><h2>One cell contain extra set of chromosomes: n+n=2n</h2>
Explanation:
If all of the chromosomes experience non-dis-junction in meiosis II, means that sister chromatids failed to separate during meiosis II then
a. half the cells are normal containing n number of chromosomes (n).
b. One cell lacks whole set of chromosomes
c. and one cell with two copies of the chromosomes (n+n).
I know that fish and marine animals are affected by this I'm not sure why its difficult to manage tho
Answer: D(nucleoid region)
Explanation:
In the diagram below the irregular shaped, supercoiled region, without a membrane, labelled D, surrounded by the cytoplasm of the cell is the nucleiod region that contains the main DNA in bacterial.
The nucleoid region in the prokaryotic cell contains the main DNA material. The nucleoid which means nucleus-like contains the main genetic material in prokaryotic cell, some satellite DNA are found in plasmid is other parts of the cell. Unlike the nucleus of eukaryotic cells the nucleiod lacks a cell membrane. The nucleiod has an irregular shape, and has a circular chromosome.
The sun moving is what causes the different seasons on earth
<span>Plants are the key to removing carbon dioxide from the atmosphere, and plants need water to survive. Plants take up water from precipitation and ground water sources. They use this in the process of photosynthesis, where carbon dioxide and sunlight are used to make oxygen and sugar.
