Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.
The blanks are weathering so that's your answer
Answer:
I-3, II-2, III-2 are all definitely carriers
It is possible find the genotype of individual II-1 because the he inherited his father's y which does not carry the trait (because only x chromosomes have the trait) and his mother's x chromosome, but the mother is not a carrier.
10. before replication begins, the strands of DNA are separated and used as templates for the new strands. the replication process creates 2 identical double helixes, each has 1 new strand and 1 old one.
11. without dna replication, damaged cells could not be replaced/repaired and cells need dna, cells would become mutated without dna replication.
12. mutations are rare because dna polymerase proofreads the strands but if the process occurred incorrectly and was not corrected by the polymerase, the cell would become mutated and could be really harmful.
hope this helped!
