c or a,
a is not right
c is correct because they need each other to live
hope that helped :)
One egg is split into two inside the body. Then two different eggs make two different people.
Answer:
Crossing over increases the genetic variation
Errors in crossover formation result in chromosomal rearrangements (duplications and deletions) and may also cause chromosome nondisjunction
Explanation:
Crossing over, also known as recombination, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during meiosis. Crossing over increases the genetic variation of the resulting gametes, allowing different genetic combinations to be passed from parents to offspring. Unequal crossing over is a type of error associated with chromosomal duplication and/or deletion events. Unequal crossing over occurs when homologous sequences are not paired precisely. Moreover, errors in crossing over may also cause chromosome nondisjunction, thereby leading to aneuploidies.

Answer:
too much nitrogen in surface runoff can cause algae to overgrow
Nitrogen fertilizers used in large-scale agriculture could leave a legacy of pollution that would persist for decades in soil and groundwater, scientists in France and Canada warned, which published a study in the National Academy of Sciences magazine, " PNAS ". According to these scientists, the excess of these fertilizers in the environment has been linked to contaminated drinking water and can cause the rapid growth of algae that compromise aquatic ecosystems and coastal marine life.
