Answer:
The correct answer will be-pachytene, prophase I,
Explanation:
Tetrad is the structure formed during the meiotic type of cell division which produces four daughter cells.
The tetrad structure is seen under the microscope during the pachytene substage of prophase I.
The tetrad structure is formed when four sister chromatids are aligned together in a cell before the crossing over event or recombination has to take place. The tetrad formation allows the crossing over to take place in pachytene.
Thus, pachytene, prophase I is the correct answer.
I'm not sure about the first one; it might be D, but the second ome
No Because There Are A Lot Of Different Elements That Make Up Just One Cell And You Have Millions Of Them That Make Up You And Different Ones For Different Functions In Your Body. So I Wouldn't Call Them Simple At All
Answer:
Cell respiration begins with Glycolysis
.
Explanation:
Glycolysis is the first and initial step in the cellular respiration. Cellular respiration is the anaerobic process, which takes place in cytosol of the cells. Two molecule of pyruvate(CH3COCOO-) are formed from 1 molecule of glucose(C6H12O6)through glycolysis. The NADH and ATP are high energy molecules formed when the free energy are released. It is the process which takes place through a series of ten enzyme catalysed reactions. 10 enzymes are required to break down the sugar molecule. It occurs in cytoplasm.
