The term 'synapsis' is associated with which process?

The term 'synapsis' is associated with crossing over process.

Explanation:

An exchange or reciprocal segmental switch between chromatids of a homologous pair of chromosomes that results in a gene recombination, is understood as a crossing over. Synapsis is the fusion of two homologous chromosomes occurring while meiosis.

Synapsis enables the alignment of homologous pairs and probable chromosomal fusion between them previous to their division. The synapsis happens during meiosis prophase I. Crossing over takes place during prophase I of meiosis until tetrads are paired in metaphase I along the equator. Even sister chromatids survive by meiosis II, and homologous chromosomes were transferred to separate cells. Notice that the point of convergence is to raising genetic variability.

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers
