Answer:
1. Meiosis I
2. Tetrad
3. Tetrad
Explanation:
Crossing over refers to an event taking place in the cells undergoing meiosis cell division during which the exchange of material takes place. The process of crossing over takes place during pachytene of prophase I in meiosis I.
Crossing over takes place when the structure formed by the pairing of the four chromatids of the chromosomes called tetrad is formed. The formation of tetrad allows the exchange of genetic sequences, therefore, result in recombination.
The process of crossing over does not take place in the mitosis as the tetrad is not formed in the mitosis.
Thus, Meiosis I, Tetrad and tetrad are correct.

Answer:
A cell will shrink when the concentration of electrolytes is greater inside the cell than outside the cell.
Explanation:
<em>When the concentration of electrolyte is greater inside the cell than its outside, water molecules move from the outside electrolyte into the cell leading to its expansion and turgidity. If the water movement continues, the cell may burst and release its contents in a process known as lysis.</em>
Hence, that a cell will shrink when the concentration of electrolytes is greater inside the cell than outside of the cell is false.
