Answer:
Crossing over ensures that organisms of the same parents have differences in genetic content making them unique in one way or the other.
Explanation:
This question is describing the process of crossing over, which occurs only during prophase I of meiosis. During the process of crossing over, alleles of a gene are exchanged between non-sister chromatids of homologous chromosomes (mother and father chromosomes).
Hence, a unique GAMETE that has been genetically recombined will be formed. When these gametes are fertilized (egg) or fertilizes (sperm), organisms that are genetically different from their parents are produced. This ensures genetic variation, which is a difference in the genetic content of organisms.
Usually the average growth cycle of eyebrows is 5 to 7 weeks, but it can be shorter or longer depending on various factors such as, your age, metabolism, and weight.
Your blood would not be oxygenated so cells and tissues and muscles wouldn't receive any oxygen
