Answer:
Weather refers to short-term atmospheric fluctuations, whereas climate explains the weather in a certain place over a long period of time.
Explanation:
Globally, weather conditions are measured at hundreds of locations every day of the year by observers and automated stations. Some remarks are made every hour, others perhaps once a day. In the long run, these weather observations allow us to quantify average long-term conditions, giving an insight into the climate of the region.
Systemic weather records have been recorded for over 140 years in various places in the United States. We can recognize patterns and trends with these long-term records. And it's our mission to collect, monitor, and arrange these data, as the official repository of the Nation for environmental data, for scientists, decision-makers, and you online.
Answer:
C) Rodents with black fur color will decrease in frequency as they are more visible to the predator against the light sand background.
Explanation:
As we know that the area that the rodents were released has a light color and a rodent predator, we can conclude that the black-colored rodents will be the ones that will be most captured by the predator and will decrease its frequency. This will happen because the brown and tan rodents are more similar to the color of the place and therefore will be able to stay camouflaged, making it difficult for the predator to see them, this does not happen with the black rodent that will be easily seen and captured.
