<span>The correct answer is d. the idea that T. rex held its tail aloft was supported by the studies of many scientists. This is how science works, things are discovered by having members of the scientific community do experiments and come to the same conclusion. Many of them confirmed this theory and a concensus was established.</span>
This is parasitism because one organism (mosquito) is benefitting (by acquiring nutrition) and the other organism (human) is harmed (by the red itchy bump).
The Miller-Urey experiment showed that simple molecules could have arisen abiotically. This chemical experiment included conditions similar to those present on the early Earth, and tested the origin of life under those conditions.
Water (H2O), methane (CH4), ammonia (NH3) and hydrogen (H2) were the chemicals used to produce the results of the experiment, the factors needed for simple life to arise. Given similar conditions on other planets, it's possible that life could arise there as well.
Hey there,
Your question states: <span>What types of local winds would you experience if you were standing in a valley at night?
</span><span>The type of local winds would you experience if you were standing in a valley at night would be like a </span>

. Based on my research, when attending the valley of any sort, you would not really see like 10 MPH winds, there winds are not powerful at all. They are little breeze that feel good. That it why your answer is Breeze :)
