➷ Waves are commonly caused by wind. However, tides are caused by the gravitational attraction of the sun and moon on the oceans.

Answer : The correct option is, U
Explanation :
As we know that there are four states of matter which are solid, liquid, gas and plasma.
Solid state : In this state, the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are fixed and vibrate in place but they can not move from one place to another.
For example : Copper
Liquid state : In this state, the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another.
For example : water
Gaseous state : In this state, the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another and spread out.
For example : Helium gas
Plasma state : In this state, the stars, atoms lose their electrons at very high temperature. The mixture of electrons and nuclei that result is the plasma state of matter.
For example : Sun
In the given incomplete table,
T = solid state
W = example : copper
U = gaseous state
X = example : water
V = plasma state
Hence, the gas would be placed in 'U' box.
Most scientists agree, it is unlikely that the lionfish's invasion of U.S. waters can be reversed. Any large-scale attempts to remove the existing lionfish from U.S. Atlantic waters appear impractical and would be very costly, because of the large geographic range and depths that the fish now occupies. Lionfish are now found along the entire southeast U.S. coastline at depths between 1 and 1,000 ft, making their complete removal all but impossible. Scientists do believe, however, that lionfish can be controlled in some locations, such as some Caribbean islands and marine protected areas. The lionfish invasion highlights the complexity of managing introduced species in the marine environment. Lionfish now join the ranks of other aquatic invasive species that have taken up permanent residence in U.S. waters, such as European green crabs, snakeheads, and zebra mussels.
1.Track the lionfish population. Although more sightings in recent years suggest that more lionfish are present, that may not be the case. It could simply be that more public awareness has led to more reports. A monitoring program is needed to determine if the number of lionfish is actually growing
2. Conduct more research. Scientists' ability to predict the lionfish's future abundance, and its effects on the ecosystem is greatly hindered by a lack of knowledge. Research is needed to determine the lionfish's ability to survive, reproduce, and grow in the Atlantic Ocean.
3.Educate the Public. People need to know that it can be harmful to release aquarium fishes into bodies of water. In the United States and throughout the Caribbean, people should be alerted to the presence of lionfish and encouraged to report sightings. At the same time, people should be cautioned against handling lionfish and made aware of the health risks from their stings.
4.Notify physicians and other health care providers about venomous fish in U.S. waters. One study of reported lionfish stings, mostly involving aquarists, noted no fatalities. Most stings result in uncomplicated wounds with severe local pain that responds well to soaking treatment. A greater risk appears to be secondary infection resulting from the wound. In addition to medical personnel and health-care providers, boat operators and lifeguards also need to be advised about lionfish stings.
5.Make regulations to control the introduction non-native marine species. Bermuda's approach, which is to enforce a strict ban on the importation of live fish, is proving an especially effective way to reduce the risk of aquarium releases. But scientists caution that the issue is more complex than simply limiting imports of non-native species. Some believe that such efforts will fail unless we learn more about how these species disperse once they are introduced into non-native waters. Although the lionfish invasion is probably here to stay, this dramatic event may prompt the development of effective strategies to reduce the ill effects of other marine invaders.
I love lionfish and marine life so this was simple for me! I hope I helped! :)
