Answer:
Cell copies its genetic material during the S-phase of the interphase during cell cycle.
Explanation:
- Cell cycle is broadly divided into two phases ; the interphase and the M-phase.
- M-phase is the dividing phase during which the karyokinesis and cytokinesis takes place.
- Interphase is the phase during which the cell prepares itself for division.
- It is further divided into G1, S and G2 phase.
- During G1 phase the cell prepares for DNA replication and the replication complexes assemble.
- The next phase is S-phase during which the DNA replicates itself and the genetic material in the cell doubles.
- The Next phase is G2 phase during which the DNA is scanned by DNA tepair complexes and errors in the replicated DNA are edited and repaired.
- At the end of G2 phase the cell prepares to enter M-phase.
Answer:
Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae
Explanation:
Hypoxia can result from lung damage due to a trauma. It can also happen if they person has bronchitis or pneumonia.
Glycolysis, a process in which the body breaks down glucose via enzymes, giving energy to the body
Answer:
The correct answer is: False.
Explanation:
- A Fishery collapse can be defined as the condition in which the composition of different species of fishes forming a food chain or a food web and located in a marine or aquatic community undergoes a drastic alteration.
- The alternation can be caused due to environmental or anthropological factors.
- A fishery collapse usually affects the larger fish population like sharks and tuna as their commercial and economic demand is higher.
- Excessive fishing cause the population of the large fishes to decline without affecting the small fish population.
- This is because the small fishes do not have high economic or commercial demand, hence they have very less probability of being angled or captured.
