Answer:Recombination occurs through
crossing over and independent assortment. The correct option is B
Explanation:
-Genetic recombination is the process by which two different DNA are disintegrated and recombined to form new pairs of alleles. The process of recombination also involves the breakage and rejoining of parental chromosome. It occurs during meiosis ( that is formation of sperm and egg cells) and it gives them the correct number if chromosomes). Recombination occurs in meiosis through:
- CROSSING OVER: this is when paired chromosome press together and break, each may swap a portion of its genetic material.
- INDEPENDENT ASSORTMENT: which is the chromosome invented from either the father or mother can sort into any gamete and this produces a tremendous genetic variation. I hope this helps, thanks!
To clearly view the morphology of the prokaryotes, one needs a microscope with higher resolution i.e magnification of ×100. Use of oil for this purpose is important because it reduces the refraction of light as it travels from air to glass. this process increases the resolution of the microscope making it possible to view morphology of bacteria.

Answer: These are the rocks that form at erupting volcanoes and oozing fissures. The magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere.
