Natural selection is an evolutionary mechanism by which (B.) advantageous traits become more common in a population.
You should always keep calm and try to think positive never put your self down never ever
The SST or sea surface temperature refers to the temperature of the water close to the surface of the ocean. Sea surface temperature influences the behavior of the atmosphere of the Earth, so their initialization into the atmospheric model is essential. While SST plays a vital role for tropical cyclogenesis, it is also essential in predicting the formation of sea breezes and sea fog.
The changes in SST reflects the overall trend of warming of the climatic system, and in turn, affects the climate and weather patterns globally. If the SST is too warm, the humidity upsurges and the greenhouse effect enhances.
Exoskeleton!!!! Tell me if it helps!!!
Most of the marine animals have a stream lined body, which means, they have a sharp and pointed at the front. The pointed front of the organism allow to cut the resistance of the water. In case, the body is not pointed at the front and it is blunt, the water current and flow would resist the movement of the organism further. So, for the locomotion purpose, it is important to have a streamlined body. Further smooth and hair less body also decrease the resistance during the movement in the water.
