Answer:
Each is a mini-ecosystems and a representation of much larger ecosystems found on earth. The mini ecosystem is the terrarium
Explanation:
A terrarium is the accumulation of small plants that are being grown in the transparent, or sealed container. It is a closed environment type and are mostly used to know how the ecosystem works within itself. Inside that small container, we can observe various natural processes like photosynthesis, respiration, as well as water cycle. Some small plants cannot adapt well in the home environment, so they can be grown in the terrarium. If they are properly planted and taken care of they can grow with minimum care. By this we can grow indoor plants with less care.
Answer: B. Melting temperatures of primer should be between 55-80 degree Celsius.
Explanation:
Bacause the melting temperature controls the binding of the primers to your template DNA. At melting temperature 50% of the primer molecules are bound to their corresponding target sequence. If the difference in melting temperature between the two primers is too high, it might be difficult to find experimental conditions where both primers can bind to their target.
They must preform photosynthesis so they can acquire energy and nutrition.
