Cross over is the first way genes are shuffled to give rise to genetic diversity. Cross over takes place in sexual reproduction. The normal way that cross over occurs is chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other.
If they break the pieces at the same locus in the sequence of base pairs, the result is an exchange of genes called genetic recombination and it ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity occurs.

Answer:
<h2><em><u>Base</u></em><em><u> </u></em><em><u>isolated</u></em><em><u> </u></em><em><u>system</u></em></h2>
Explanation:
<u>Fixed based system:- </u>
A fixed-base building (built directly on the ground) will move with an earthquake’s motion and can sustain extensive damage as a result.
<u>Base isolated system:-</u>
A base isolation system is a method of seismic protection where the structure (superstructure) is separated from the base (foundation or substructure).
<em><u>Hence</u></em><em><u>,</u></em>

Answer:
Reducir las actividades humanas.
Explicación:
Reducir el uso de combustibles fósiles, el uso de vehículos que funcionen con electricidad y plantar más plantas y árboles son las acciones que propondría para ayudar a que la biosfera y sus ciclos no se vean afectados. La biosfera se ve muy afectada debido a las actividades humanas, por lo que para conservar la biosfera y mantener su ciclo, tenemos que reducir las actividades humanas que causan más daños a la biosfera.
