plastic items take up to 1000 years to decompose in landfills. But plastic bags we use in our everyday life take 10-20 years to decompose, while plastic bottles take 450 years.
I hope this helps
Answer: Nucleic acids
Explanation:
Nucleic acids are biologically occuring polynucleotides in which the nuclotides residues are linked in a specific sequence by phosphodiester bonds.
The two types of nucleic acids are DNA which is double stranded and serves as the usual carrier of genetic information while RNA which is single stranded serves a carriers of genetic information in some viruses only.
Answer:
1. The benefits include safer and more efficient nuclear power plants. The kind of energy that is produced is clean with no greenhouse gases and the cost of operating a nuclear power plant is inexpensive. 2.In terms of the disadvantages of uranium, it can have deleterious health effects and can lead to death because of its radioactivity. Radioactive waste is also an additional issue, if it is not disposed of at a safe place and not stored properly, it can leak radiation. Such emissions can last for centuries.
3. It produces no greenhouse gases or other waste and Tides are easily predictable. 4. High tidal power plant construction costs, Negative influence on marine
Explanation:
Answer:
it is a cell.
Explanation:
the cell is the structural and functional unit of all living organisms
Answer:
The variation might occur in the population that leads to the evolution of the species. This variation may occur due to natural selection, mutation or recombination.
The variation might change the genotype and allelic frequency of the population and might also change the phenotype of the individual in the population. The breeding adults of the left mouthed in 1981, 1987 and 1990 shows variation and was equally opposite phenotype which is more common in the population.
