Answer: It is important to control the variables so the evidence from the experiment are as accurate as possible.
Answer: nitrogen base on the tRNA
Explanation:
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.
The tributaries carry small amounts of salt into the lake
<u>Explanation</u>:
The Greatest salt lake is one of the most saline inland water body in the world.The water carried to this lake by the tributaries is very less as compared to the amount of the salt present in the lake. Rest part of the salt remains in the lake as such.
When the water from the lake gets evaporated, it leaves behind the salt. When time passes by, or years of inflow and evaporation salts they gets deposited layer over layer. The amount of salt added leads to formation of new minerals on the sea floor.
