Answer:
Continuous variations are formed due to chance segregation of genes during gamete formation, crossing over and chance combination during fertilization. They can increase adaptability of the race but cannot form new species.
Photosynthesis and chemosynthesis
Release digestive enzymes and absorb digested organic material.
Really hope this helps
Answer:
Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome
