Answer:
Black fur is more fit to survive in the environment than other colors of fur.
Explanation:
"Fitness", in terms of natural selection, is an organism's likelihood to survive in a given environment. Assuming that the increase in black fur is significant (Not attributable to pure chance), we can safely assume this is because Black Fur provides a competitive advantage in said environment over other colors of fur. There may be black terrain that allows them to blend into the environment and ovoid predators, or maybe it keeps them warmer if it is located in a cold region, thereby reducing the amount of resources they need to spend to stay warm.
When a Ribosome in the cytoplasm attaches to a mRNA molecule (I’m in 9th grade and we did this last semester so I’m pretty sure it’s right) :)
The correct answer is A.
Both DNA and RNA are types of nucleic acids. DNA stands for deoxyribonucleic acid , while RNA stands for ribonucleic acid.
Both DNA and RNA carry genetic information. However, DNA is chiefly responsible for storing and transferring genetic information whereas RNA acts as a messenger between DNA and ribosomes during the process of protein synthesis and directly codes for amino acids.
DNA is double stranded while RNA is single stranded.
DNA has thymine in its structure but RNA does not. Instead in place of thymine it has uracil.
