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:
Answer is letter D) these fungi would be known as decomposers
The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells.
Answer:
Explanation:
A paradigm shift is a major change in the concepts and practices of how something works or is accomplished.
A paradigm shift very often happens when new technology is introduced that radically alters the production process of a good or service.
Although the idea of paradigms has been around for quite some time, the concept was explored by physicist and philosopher Thomas Kahn Kuhn.

Think about a severe weather situation you have experienced near your home or have witnessed on the news.
The question is asking you to tell about any severe weather that you have seen, heard, or you've experienced about and just tell them about it.
