Answer:
Crossing over
Explanation:
Crossing over is the process during which two chromatids of two homologous chromosomes exchange part of their genetic segments. It occurs during the pachytene stage of prophase I of meiosis I.
Linked genes are mostly inherited together and do not exhibit independent assortment. However, when linked genes are present far apart from each other on the same chromosome, crossing over can occur between them to produce recombinant chromatids. Therefore, crossing over can break the linkage and produce recombinant progeny as it occurs during the independent assortment of unlinked genes.
B. Positive feedback, it decreases body temperature.
Answer:
The electron transport chain is the third and final step of cellular respiration. At the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen which the cell has consumed and reacts with it to form water. Therefore, water is created as a byproduct of the metabolism reaction.

The DNA is condensed before replication in the form of chromosomes and then the chromosomes are divided.
