A and C are the same and thus both wrong. B. The higher the temperature, the more molecules start moving, the more space inbetween them and thus the larger.
Answer:
Crossing over
Explanation:
The onset of meiosis is characterized by shortening and thickening of genetic materials to form visible threads. Thereafter, homologous chromosomes pair up to a 4-chromosome structure known as tetrad.
