Answer:
Just one round without DNA repair
Explanation:
When an error occurs before or during replication, in a normal system, there is always proofreading and correction. If the error is not corrected during replication, it can then be corrected by the DNA damage repair system. But if not also corrected, the error becomes fixed and subsequent replication will produce this error
The decomposers are of two kinds, aerobic decomposers and anaerobic decomposers. The aerobic decomposers need the oxygen from the air to break down the dead and decaying matter into simple salts, sugars and hydrocarbon gases. The anaerobic decomposers do not require oxygen for the break down of dead and decaying matter. They break down the matter into various forms of hydrocarbons, sulphides and nitrogenous compounds.
When a dead and decaying matter gets buried deep within the Earth where there is an absence of the decomposers, it takes the form of crude oil, coal, peat, asphalt, and natural gas. The matter gets compressed by the weight of the rocks above and changes its form.
After phosphates and nitrates enter a water system, the steps of eutrophication include the rapid growth of algae, death of underwater plant species, depletion of oxygen in the water, and the death of fishes and invertebrates. The correct option would be B.
Eutrophication refers to the excessive enrichment of water bodies by nutrients such as phosphates and nitrates thereby facilitating the rapid growth of some aquatic species with negative effects.
Once a water body becomes excessively enriched with phosphates and nitrates, the following is a sequence of events that follows:
- Algal bloom: the nutrients facilitate the rapid growth of algae
- The bloom of algal species results in the death of underwater plants as a result of inadequate light.
- The death of the underwater plants and the accompanying microbial activities in decomposing them cause oxygen levels in the water to drop.
- Reduction in oxygen level causes fishes and other water invertebrates to die due to hypoxia
Therefore, the correct steps of eutrophication according to the illustration is IV, II, I, and III.
