<span>Our biosphere is the global sum of all ecosystems. It can also be called the zone of life on Earth, a closed (apart from solar and cosmic radiation) and self-regulating system. Geology studies the Earth, and has tendrils in all ecosystems, thus the connection to the biosphere.</span>
Answer:
4.) He did that simply
Explanation:
I'm just guessing it's 1 because the other answers don't seem reasonable
Only urchins were removed, which resulted in an increase in limpet population and decrease in seaweed cover.
- Sea urchins and limpets both consume seaweed, making them competitors for it. The limpet population grows as a result of the urchin removal, having a greater impact on the amount of seaweed present.
- The biodiversity of these settings can be wiped out if seaweed builds up in bodies of water. This issue arises when there is an overabundance of algae, which, in search of additional food, proliferate aggressively and cause pollution.
- Additionally, life might end where there is pollution. Hedgehogs and limpets can play a significant role in this situation because they feed on seaweed, which helps to control the problem of its excessive profusion.
- A lot of research has been done to determine the value of these two species in preventing pollution brought on by the growth of seaweed.
- When the sea urchins and limpets were removed in the study mentioned in the question above, seaweed cover rose significantly more than when only the sea urchins were removed.
- This most likely occurred because the limpet population expanded and the amount of seaweed was reduced when only the hedgehogs were eliminated.

Explanation:
Hi there!
Cell cycle has 2 phases (i.e M-phase and Inter-phase). Interphase is considered to be the longest phase. Interphase also has G1-phase, S-phase and G2-phase. In cell cycle while moving from M-phase it has two option either to go in G1-phase or G0 phase. It it goes to G0-phase it doesn't go under cell division but if it goes to G1-phase it starts to prepare materials required to replicate or copy DNA. After preparing all the material it goes in S-phase and copies DNA. It doesn't go to G2-phase until it copies DNA perfectly. Then it goes to G2-phase. In this phase it prepares material for replication of other cell organelles.
Therefore, DNA is copied in S-phase.
Hope it helps!
