Answer:
I think the correct answer is D
Hairpin like structures are formed in both DNA and RNA but are common in RNA than in DNA. This is because DNA can be double stranded or single stranded while RNA is generally single stranded structure that can be double stranded only when it forms a hair pin like structure.
The features of hairpin structure in RNA are as follows:
1. This structure is a building block of many secondary structures of RNA.
2. The termination sequence during transcription also forms a hairpin loop like structure.
3. tRNA also forms a hairpin loop like structure and helps in the process of translation.

Answer:
One change to Earth's surface can result in changes to other Earth systems.
All of the spheres on the Earth are interconnected, and they constantly interact with each other. When there's a change in one of the spheres then the other ones have changed as well. This is the case with the hydrosphere and the atmosphere. The atmosphere is becoming hotter in the past few decades, and this is contributing to the increased temperature of the hydrosphere (in this case, the sea surface). With the increasing temperatures of the sea surface, the cyclone activity becomes bigger and stronger, and this contributes to lots of natural disasters. So we can easily see the interaction and changes in this case between the spheres;
* atmosphere gets hotter - temperature of the sea surface rises - bigger cyclone activity.
The answer is A. Putting the aquarium in the dark means that
the aquatic plants will not be able to photosynthesize. The process of photosynthesis produces oxygen
as a by-product. The oxygen is used by the fishes in respiration and release
carbon dioxide. The carbon dioxide is used by the aquatic plants in photosynthesis.
