<u>Answer</u>:
"It increases the mutation rate" is an advantage of sexual reproduction
<u>Explanation</u>:
The basic thing of evolution is fundamental, as it helps in generation of genetic variation on which the selection can act. Sexual reproduction leads to genetic diversity, and this genetic diversity leads to increase the mutation rate. Genetic diversity occurs because of two various cells which are combining together and biological assortment which happens at the time of cell division. Neutral genetic diversity in the population leads to high mutation rate.

Answer:
3) Condensación del agua en la naturaleza
El vapor de agua sólo se condensará en otra superficie cuando ésta sea más fría que la temperatura del vapor de agua, o cuando el equilibrio de vapor de agua en el aire, es decir, la humedad de saturación, se haya excedido.
Explanation:
Answer:
metaphase
Explanation:
The easiest stage of mitosis to identify under the microscope is the metaphase stage.
<em>The stage is characterized by the alignment of chromosomes at the center (the equator) of the cell forming what is known as the 'metaphase plate'. The metaphase plate can easily be seen at a glance under a focused microscope. Other stages of mitosis are continuous and will take a bit of effort to pinpoint a particular stage from the transition stage. </em>
