Abiotic
An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system. <span>

Plants
Microorganisms
Macroorganisms
Think of it like this. Horses do a LOT of galloping, which is hard on the feet! Hooves are a physical ADAPTATION, so that the horses won't experience pain on their journeys. They're hard, so that the horses don't feel the ground nearly as much. Now, mountain goats travel over rough terrain, with sharp rocks and steep inclines. Again, it's really easy for them to get hurt strutting around the mountains, so they evolved hard hooves to protect their feet.
Answer:
Eight (8) different artificial mRNA 3 nucleotide codons possibly made.
Explanation:
According to above scenario, when we add polynucleotide phosphorylase into the solution of adenosine triphosphate and guanosine triphosphate there will be 8 different artificial mRNA containing 3 base sequence (codons) possibly be made while if code involves two base sequence there will be possibly 4 different codons.
Answer:
There will be three spots that will light up.
Explanation:
There is a research paper published which demonstrated the trisomy of 21 chromosome. They found out that there are total three spots that light up in Trisomy 21 (down's syndrome's fetus). I have attached picture from research paper and provided the reference below.

Answer:
This is abut the water cycle I believe.
Explanation:
I don't know for sure but it looks like it is.
