The exchange of genetic material between non-sister chromatids that may result in new gene combinations on the chromosomes is called the random assortment. It involves formation of random combinations of chromosomes in meiosis and of genes on different pairs of homologous chromosomes by the passage according to the laws of probability of one of each diploid pair of homologous chromosomes into each gamete independently to each other pair.
If blood typing is not available in an emergency situation, O-Negative blood is universally accepted by all blood types because it is absent of any antibodies. Therefore, if O-Neg blood is on hand in emergency situations, it can be given to anyone.
Answer:
Excessive nutrients from fertilizer run off.
Explanation:
Scientists have suspected that phytoplankton blooms might be connected to agricultural run-off. They got some evidence from a recent study by comparing the timing of irrigation along the west coast of Mexico and phytoplankton blooms in Mexico’s Sea of Cortez. During the comparison, they had found a close correlation. Phytoplankton blooms occurred in the Sea of Cortez shortly after the irrigation. This happened because of carried fertilizers after irrigation and other agricultural run-offs into the sea.
The bloom detected in the Gulf of Mexico on December 13 might be similarly linked to agricultural run-off.
Because it needs to be able to be proven and it avoids being incorrect.
