Explanation:
crossing over is a process that happens between human organs chromosome in order to increase general diversity. during crossing over part of one chromosome is exchange with another. the result is a hybrid chromosome with a unique pattern of genetic material. gametes gain the ability to be genetically different from their neighbouring gametes after crossing over occurs. this a loss for genetic diversity which will help cell participate in survival of the fittest and the evolution.
The answer is (C) Replication
Though occasional errors could occur in cells during replication; the cells have error checking and proofing mechanisms that reduce the rate of error to one to several million replications in higher eukaryotes.
After all, one mismatch error during replication would not result in major effects. The others choices, however, have higher rates of causing genetic abnormalities.
Mercury has the smallest orbit and neptune has the largest. so neptune would take a longer amount of time to orbit the sun.
The answer is H. He is mechanically digesting his food.
a chemical reaction plants use to create food
