<u />
Explanation:
Within a community, certain novel traits are fixed because they impart beneficial adaptations on an individual in their ecosystem (like mate attraction). Such modifications enable such individuals to live longer than their peers, and breed over time to produce more offspring who also exhibit these traits.
Natural selection takes place and is determined by the fitness of an individual
, it contributes to evolutionary change as individuals with certain traits reproduce, the traits become fixed and prevalent within the population.
Answer: option B) Statement is false
Explanation:
Living things are NOT composed only of organic elements. Organic elements refers to compounds of Carbon, whereas living things such as Vertebrates (man, shark, lion etc) possess bones, teeth with INORGANIC components like phosphorus, magnesium, calcium.

Yes they can to create new tissues
They both contain a Nucleus, the part of the cell designed to dictate the cells operations.
You did not included your list of selections. Some general properties ascribed to DNA are storage and expression of information and variables through mutations. Replication, Transcription, Translation and Mutagenesis are the major functions of DNA in a cell. DNA nucleotides contain deoxyribose. DNA is double-stranded in the conservative mode, the original double Helix remains a complete unit and the new DNA double Helix is produced as a single unit. In the double=stranded DNA, Hydrogen bonds hold one complimentary strand to the other.
Hope this helps, I love Science.
