Answer:
basically every living thing breathes oxygen O2 and exhales carbon dioxide CO2
Explanation:
So orcas use O2 and produce then CO2.
Lipids macromolecules are the main part of cell membrane
Answer:
c. Thymine dimer
Explanation:
Thymine dimer
Thymine dimer ( also called the DNA damage ) that is repaired by the nucleotide excision repair which involves the breakage of the phosphodiester bond on the side of the damage , and results in the excision of an oligolnueotide of 10-12 nucleotides in length .
But the base excision repair involves the removal of the damaged base , removal of short polynuceotide and resynthesis of this area with DNA polymerase .
2 daughter cells, 12 chromosomes each
mitosis maintains diploid number, only meiosis becomes haploid (half number of chromosomes)
