As the question is incomplete and there are no statements available based on which the question can be answered. But based on the knowledge it can be answered.
Answer:
Most of the corals contains photosynthetic algae which are known as zooxanthllae which lives in the tissues of the corals. Algae and corals have mutualistic relationship.
The corals provide algae space to live and algae provides coral food such as glucose and glycerols to them which are considered as products of photosynthesis.
If the producers are hampered by the catastrophic event then the main source of the food will be hampered. There will be less or no food source for the corals which covers a large area in the marine ecosystem.
There are chances that there will be more load on the other photosynthetic organism in water as there will be more population dependent on them for food.
Hence, if there is a loss of habitat for these protist other levels of food chain will be affected due to inter connection.
Answer: Option 4.
The fresh water is hypotonic and the salt solution is Hypertonic.
Explanation:
Hypotonic solution is a solution that have little dissolved solutes i.e low osmotic pressure compare to other solution. When a cell is put in hypotonic solution, it take in water and the cell swell up and it does not burst due to it's cell wall thereby becoming turgid or hard.
Hypertonic solution is the solution where the concentration of solute is higher outside the cell than inside the cell. Example is saline water.when a cell is placed in Hypertonic solution it will shrinks because it losses water.
Answer:
They regulate the cell cycle by phosphorylating other proteins
Explanation:
they are serine-threonine kinases, they play an important role in the phosphorylation of other proteins. Cyclin-CDK complexes phosphorylate substrates appropriate for a particular cell cycle phase and without that, the cycle cannot continue.
