Answer:
2)chiasmata hold chromosomes together.
Explanation:
Chiasma (pl. Chiasmata): it is the point of contact, the physical union between two non-sister chromatids that belong to homologous chromosomes. In a given chiasma, an exchange of genetic material can occur between both chromatids.
1) is FALSE becasue recombination occurs between chromatids of homologous chromosomes, NOT between sister chromatids.
3) is FALSE because more than one recombination event can occur in a given pair of homologous chromosomes.
4) is FALSE becasue synaptonemal complex keeps homologous chromosomes together, NOT sister chromatids. Additionally, recombination occurs in prophase 1, long before anaphase 2.
I hope you can read everything well. I didn’t write the full word, just the beginning but it should hopefully make sense.
Answer: Deep ocean currents are density-driven and differ from surface currents in scale, speed, and energy. Water density is affected by the temperature, salinity (saltiness), and depth of the water. The colder and saltier the ocean water, the denser it is.
