Answer and Explanation:

Nondisjunction occurs when homologous chromosomes fail to segregate during anaphase I or sister chromatids fail to segregate during anaphase II. The result is an addition or loss of one or more chromosomes. Nondisjunction is associated with disorders like Down's syndrome due to an extra chromosome, Klinefelter's syndrome or Turner's syndrome. These phenomenon where one has three members of homologous chromosome is called trisomy.

Answer:

Prokaryotes lack membrane-bound organelle like mitochondria and chloroplast which is used by eukaryotes to synthesize ATP but ATP synthesis also takes place in prokaryotes. The electron transport chain and ATP synthetase of prokaryotic cells are embedded in the cell's plasma membrane of the prokaryotes.

The ATP synthesis in prokaryotes is similar to eukaryotes. NADH releases electrons to the electron carriers that are embedded in the plasma membrane which causes the translocation of H+ ions to the cell membrane outer face against the concentration gradient.

Then these electrons pass through the ATP synthetase which generates ATP for prokaryotic cell. So cell membrane is the physical place where ETC and ATP synthetase are present.

Numbers 1-5, if you know the answer to any of them, even just one, that would help:)
trapecia [35]

1.  Respiratory brings oxygen and nutrients to the cells, while the circulatory

moves gases in and out of the blood. These work together because they have to exchange carbon dioxide and oxygen with each other.

2.   The main parts and functions of the respiratory system are, the nose, pharynx, larynx, trachea, bronchi, and the lungs. As I said in the first answer, The respiratory brings oxygen and nutrients to the cells.

3. The main parts and functions of the circulatory system is the heart, lungs, arteries, veins, coronary, and portal vessels. The circulatory system moves gases in and out of the blood.

4.  There are two main parts in your lungs, the pharynx, and the larynx. So, when you swallow food, the epiglottes blocks the entrance to these two main parts. Simply..if you could breath while doing this..I think you could die.

5. They are connected to capillaries that distribute blood to and from all the cells.
